The Orion 90mm achro OTA on sale again...
      #3402387 - 10/21/09 03:02 PM

This time it's $104.95 instead of 99.95. Still a ridiculous deal if you ask me.

I saw that. Ordered it Monday, it shipped Tuesday, arrived today (Thursday). I have to say it was very well packed with enough bubble wrap to start a small packaging business. The OTA was also wrapped in tissue paper, which was a nice touch. The focuser seems to be plenty smooth, and the small finder is straight through but correct image, so it may be a keeper. Also came with a 45 degree erect image diagaonal, which I'll probably never use, and two Orion Sirius Plossl eyepieces, 25 and 10mm.
But I didn't order the rain that came with it, so no idea yet how it performs.

I showed this scope - and importantly, the price - to my wife, and she asked, "Do you want it?" (Duh.) So she said, "Alright, that'll be your Christmas gift."

It's on order now.

- Celestron C8+, Orion 90mm f/10, Orion ST-80, 5" f/8 Dob, 127mm f/9.4 refractor, 114mm f/8 on DS GoTo, 60mm Sears 6333-A, 127mm f4.4 refractor lens (current project), 12" f/5 mirror (future project)
- Orion Vista 10x50s (5 deg), Sears #6207 7x35 (7 deg), Jason #138 Statesman 7x35 (11.5 deg)

Yes, I'm addicted to telescopes and binoculars. I am getting help. Every time I look at the heavens, it helps.

I just recently had the opportunity to look through this scope and was VERY impressed! This is a real sleeper and and would be an outstanding first telescope. I was very pleasantly surprised to see such great images through this inexpensive OTA. Good contrast, sharpness, very little or no false color depending on the intended target. No coma, nice rings on star test, some color on out-focus but no issues when focused.

If you're looking at giving someone a very good, first refractor - this one is it! Orion just needs to change out the 45 degree diagonal for a 90 degree star diagonal.

That's a fact!
Nice that Preston has actually viewed through one and gave it a thumbs up. That means much in my book.

Thanks Doug!

As to SO be expected, I wanted to take it out for a second light, mount it on my ASGT mount and give it the "full tour" but it has been raining ever since!

I have the Meade version of this scope and I'm constantly amazed how good a starter scope can be. I bought it just for terrestrial use and camping and it turns out to be my favorite quick-looker.

I've had mine for a week now. It was raining when it got here and it's still raining - ARRGGGHHH!
I did manage to get a peek at the moon and Jupiter through some brief sucker holes with the 25mm Sirius from under a carport. All I can say is the moon was very sharp and there was no CA visible. Jupiter was also sharp and clear with both bands clearly visible. Still would like to see what it can do at higher powers and on Epsilon Lyrae, but judging by the forecast, it might happen by Christmas.

It's looking now like there could be some clear skies over the next week or so. I usually don't think of early November as a good time for astronomy, though this year we might luck out (provided stubborn inversional valley fog doesn't become too much of a problem). Actually we've gotten quite a few November ridges in recent years, but most of them have been accompanied by fog inversions and moderately cold temperatures (40s) in the valleys.

Glad to hear that you're enjoying your scope, John. My original plan was to save up and get one of these as a Christmas gift to self. However now I've been flirting with the idea of selling the Mak and going for an Orion 80ED instead. The ED's short focal length would be a big help when trying to find things. But who knows? If I can't get a Mak buyer within the next 3 or 4 weeks then I might just go ahead and order this one instead.

This achro gets excellent reviews; it's making me wonder if it's really not that far behind the ED80 in performance...?

Looks like it's not on sale any more. Here's the link to the scope:

http://www.telescope.com/control/product/~category_id=refractors/~pcategory=telescopes/~product_id=09190

It was at $104.95 as of Tuesday night, since that's when I ordered mine. Not on sale now, it seems. I'm glad I didn't wait!

Even so, it really is a great deal even at $129.

These 90s are extremely capable. Back in August I followed the disappearance of Saturn's rings up until 3 days before crossing. I saw the Wesley event before knowing what it was. If you concentrate you'll be amazed what you can see on Jupiter. They are perfectly set up for Orthos.

I finally got some clear skies tonight, so I had a chance to see what this scope can do - and to be honest, I really didn't expect a whole lot from it.
The seeing was nice and steady for a change, so I spent over an hour on Jupiter. I started with a 30mm Tak and kept working my way up in magnification as the scope cooled. The best view was with an 8mm TV Plossl (114x), so I stayed with it for about 30 minutes. I could easily pick out irregularities in the NEB, but couldn't quite resolve them into festoons. The southern belt wasn't quite as dark, but I could still seem some irregularity in it. There was a thin belt just visible above the NEB, and some shading near the south pole also. Overall the view was sharp and well defined with the 8mm.
I put the 3-6mm TV zoom in and could get a decent image at 6 and 5mm (152x and 182x), but that was the limit. I could glimpse some detail at 4mm (228x) and at 3mm (303x) the belts were just about gone - but all four moons were still reasonably sharp! The focuser is decent, and the scope snaps right into focus, but if I had been working with a two-speed focuser, I probably could have coaxed some detail out of Jupiter at the 3mm setting.
I turned the scope to Epsilon Lyrae with the 8mm in it and was surprised to see both components cleanly split with dark sky between them. I switched to the 10mm Sirius Plossl (91x) that came with the scope and still had a clean split, so I moved up to a 15mm TV Plossl (61x) and could barely get some separation, but when the seeing was steady, they were cleanly split.
I took a quick look at Vega and for the first time I noticed a bit of CA, but it certainly wasn't a rainbow of colors. There was some green and yellow in and out of focus, but the rings were nice and concentric.
I swung over to Albireo to see what the colors would look like - very blue and very gold with both the 8 and 10mm Plossls. Polaris is always worth a look, and is a good test for a small scope because of the contrast in magnitudes between the two stars. I had no problem at all picking up the faint companion even with a 20mm Plossl.
I found I really didn't need any kind of red dot finder on this scope. I just sighted along the tube and then used the 6 x 26 correct image finder to center the object.
Regardless of whether the price is $104.00 or $129.00, this is a heck of a scope. I think Preston made the comment that this would make a good Christmas scope for someone. It's many levels above the worthless dime store scopes that are usually sold at this time of the year, and it really is possible to do some decent work with it.
Now, if I could convince myself it's worth adding a $150 GSO two-speed focuser to a hundred dollar scope ................

None of this surprises me. I had one of these scopes in the 90's and used it extensively alongside an 8" dob. I'm not really sure why I ended up selling the thing.

Anyway, I've been looking for something a little more "grab~n~go" than my 120mm f/8 on a Williams optics EZ mount and I remembered that the 90mm f/10 OTA on the aluminum alt-azimuth mount was very quick and easy to set-up. (Note - not saying the 120 f/8 on EZ mount is not highly portable - but sometimes I want to be able to grab everything I need in one hand and go.)

I also wanted something that my kids can more easily use when they want to join me while I'm observing.

So I've been browsing different sites and found that SkyWatcher was having a sale $170 for the 90mm/f10 scope, altazimuth mount, 2EP, red dot finder, and star diagonal.
I've been pondering whether or not to get it for a week.

Last night I happened to notice that the sale was ending 10/31 (last night). So I filled out the order, went through the checkout and was sitting there staring at the submit button and the final $197 charge it added to with discounted shipping costs. Money is tight, so I only buy something if I have enough in my "play-pal" account -- but even then I feel a twang of guilt every time I buy a piece of astro equipment.

Just then my youngest daughter -who was having a friend over - came in and asked me for the 2nd time if she could have the laptop. Since she was the child in particular I was thinking of when I began thinking of buying a smaller scope to have, I took her timing coming in as a sign I should hit the submit button.

So the order has been placed.

I had the Orion version in the 90's. I imagine the skywatcher version should be the same optics. I will let you guys know how it performs. The mount that comes with this scope is the same alt-azimuth that came with the one I bought in the 90's. I liked it -- lightweight, slow motion controls, sturdy. I don't remember there being any vibration issues.

Anyway, If the optics perform as well as I remember then I would rank this scope/mount combo as one of the top values on the market considering the quality and what is provided.
Especially as a scope for beginners and kids. Even without the sale prices and shipping discount the whole package would have been $227 at regular cost.

Had a chance two nights ago to spend some time with the Orion 90 observing the moon. Tested the scope with a Hyperion 8-24 Zoom and a 9mm University H.D. Abbe Othroscopic.

Great Views and no CA issues for such an inexpensive scope. Had a great time checking out mountain ranges, crater walls, rilles, microcraters, all of the Apollo landing sites and the marbling effect of interplanetary dust fluxes on the lunar surface.

While I doubt that I will get such great views. And will take your review with a grain of salt. I am nontheless waiting inpatiently for my scope to arrive. Hurry up UPS dude... Hurry up already!

Just got my Orion 90mm achro delivered at my door. Initial impression is that for $95 it is a very good deal. There are some minor cosmetic paint issues (the paint on the dew shield is not even on the edges and where the dew cap is placed the cap has scratched the paint) and the dew shield is also loose (if you try to remove the dew cap the dew shield comes off ), but that should be easily fixed. As for the focuser it is OK but not great (but I didn't expect a FeatherTouch either!)

Now the view... a quick view of a pine tree 200ft away showed very nicely with the 25mm Sirius Plossl. The view with the 10mm was good too but was a little harder to get the focus to snap. I hope to try it out tonight for some astronomical viewing

Overall if you need a starter scope or a 2nd (or 3rd,...) for public views you can't go wrong with this scope

I just received today the Skywatcher version of this scope with the alt-azimuth mount. Total cost with shipping was $197. I figure it is a great scope for my kids to be using while I'm out with my larger refractor.

But I don't think you can beat the price for everything you get with it. I'm anxious for some clear nights so I can test the optics.

Mine arrived yesterday too!

I heard the UPS truck roll up and met the driver at the sidewalk as he was walking up SWINGING the box by one of the two wrapping bands. I said "Hey be careful that's a telescope!" to which he replied..... "That's OK we ship these things all the time". At that point I figured there was no point arguing with his superior logic and submissively took possession of my new purchase. The box as delivered by UPS was crushed, partially opened and had puncture holes in it. As I was walking back into the house with tattered box in hand I said a prayer that must have resonated with the proper Gods because the scope was unscathed.

Upon opening the box I was struck by the size of the scope. It is much larger than I thought it would be (relative newbie here). The fit and finish is IMO superb (for a $95 scope). I was also very pleased by all the accessories that were included, everything that is needed to start observing right away except for a mount.

My only mount is an older Super Polaris that has only ever held my SP-C6 reflector and does not have a dove tail saddle. Unfortunately the rings that came with the the Orion scope could not be used with the existing bolts on the mount that fasten the rings for my reflector. My heart sank quickly thinking that I would have to wait to try it on my mount until I can find the proper bolts. Then I realised that I could use the bolts that fasten the dove tail plate to the rings on the new scope. I was in business!

By the time I got it on my mount it was kinda late AND cloudy so I could not give it a test. Maybe tonight.

All in all I can not believe that Orion could sell this scope for $95..... freakin' $95!!! If this scope performs as well as my Orion ST80 I will be very happy and for sure convinced that I got one sweet deal!

They are now "out of stock." (If I were a scope retailer I'd get a clue and raise the price, but apparently we can profit off of their ignorance to this fact, so I won't complain )

Had first light with my new scope this morning. It was hazy and cloudy, seeing sucked and it was just starting to get light, but got some pretty decent views of the Moon. I only used the eyepieces that came with it, the 25MM and 10MM Plossils. This scope definitely out performs my ST80 which is all that I was hoping for. I was pleasantly surprised by the focuser. It works just fine.

I have this mounted on my Super Polaris mount and it is extremely solid. Vibration when the mount is tapped is negligable and when the scope is tapped it settles down in a second or less. Also better than I was hoping for.

The finder leaves a lot to be desired so that is the only thing that I am disappointed with.

Overall this scope is a killer deal for $95. I plan to use this as a quick G&G for short backyard observing sessions. I have extreme light polution and many houses and trees blocking my views. So I didn't want to spend a lot of money on a quick G&G. And as I stated I was hoping to get a scope that at least performs as good as or better than my ST80 that provides a bit more magnification.

I can't wait to do a side by side with my Celestron 6" F/5 reflector!

Mine is due to be delivered today. It's been cloudy and raining for a week, I guess I've just guaranteed a least another week of clouds and rain?

Still excited about this deal from the other posts.

Am excited to hear your first (and second) light tales on this scope. The reason is that I want to have a backup plan should my Mak-to-ED80 scheme prove unworkable and I need to compromise somewhat on my refractor choice. I'd like to know how good this one is on planets (contrast, ability to manage atmosphere, and magnification tolerance) relative to the ED80. If it's at least almost as good as the ED80 then it would be a worthy emergency compromise scope. Since I'm not planning to buy any 2" eyepieces in the immediate future, my potential FOV would only be reduced by a third by going for the 90...

(update 11/16) UH-OH. The product no longer shows up in the general online catalog of refractors. This after a somewhat extended out-of-stock period after being available at a steal price. I'm scared that it may have gotten hit by the ugly "D" word. If so, will there be another fairly cheap 80-100mm f/10ish achro OTA package that comes along, or does this represent the end of an era?

Hey Karl, regarding your update, I wondered the same thing. I had my 90mm on lay-a-way (sucks only working 4 days a week, but I can't complain too much - I'm still employed!), but after noticing that it was "out of stock" (even though Orion SAYS they "hold" lay-a-way for you), at payday my wife and I managed to scrape together the money to pay it off. Well, I waited... and waited... and - WHEW! It shipped! Due to arrive on Friday.

Which of course means it will be cloudy for another two weeks after that...

In any case, I do wonder if this is an item that Orion has decided not to keep around - that would be a shame. It's a really great deal, and I hope they get more in stock soon so you can pick one up.

If they decide to discontinue it you can get the Skywatcher 90mm f/10.1 achro. I picked up one for my kids. It came with an altazimuth mount a barlow, several eyepieces, star diagonal -- for $197 shipped.

Got mine today - I haven't had a chance to look at a dark sky with it yet, but my initial impressions overall are, "Nice scope!" I was able to look terrestially about 1/4 mile away, and focus seemed sharp, and objects snapped nicely into focus for me, both with the 25mm and 10mm Plossls that came with it. The only time I had trouble was when I put my barlow in the focuser ahead of my star diagonal - but that's also about 270x too. Perhaps a bit unfair to push it well beyond it's intended limits and then say, "I had trouble."

Anyway, naturally the sky is cloudy tonight. Hopefully I can peer between the clouds in a few minutes and see if I can nab Jupiter, but I"m not optimistic. I'm "supposed" to have better skies tomorrow... here's hoping!

Incidentally, I emailed Orion about this scope to see if they are planning on bringing in more and keeping it as a stock item - that was over 24 hours ago now, and no response. I'll advise how they respond, if they get back to me about it.

I just emailed them too, basically asking the same thing. Here's the link if anyone else wants to do it:

Email Orion

It would be great if enough emails might make them rethink about still offering the OTA.

Well the telescope industry is not nearly as large as things like clothing, food, cars, etc. etc. so it will take far fewer requests to move them. That makes it well worth the effort. I just sent my request in, even pledging to buy one in the near future if they restock it!

Everyone! Write or call them and request that it be continued![\b]

Hey!!! Even though these are not the deal of the century like the Orion scope, Optics Planet has three 90mm AZ type scopes on sale all for less than $200.00. One is a Sky-Watcher, one is a Meade and the last is a Celestron. I think the Meade was the least at $159.00. I bought a 60mm Meade at a yard sale for my daughter about three weeks ago and I was going to upgrade the focuser to 1.25" which would cost me $40.00 but now I just think I will take that money and buy her one of the afore mentioned scopes.

Is that Sky-Watcher 90 the same OTA as the Orion? Maybe it could be found without mount, or if not, is the mount at least a little sturdier than a Meade EQ2?

Well, the astronomy gods smiled on me, and the clouds, though still visible, parted sufficiently to get some DSO observing in! Alas, I never got a chance to see Jupiter. But I did take this scope "around the block" for an hour or so, in between various clouds. I live in a "red" light pollution zone that borders on orange, so I have "so-so" skies.

- First, Rigel, to check for CA. I used a couple different eyepieces. Is the CA there? Yeah. Is it bad? Depends on your definition of "bad CA." I didn't find it particularly objectionable. There was a slightly purpling around Rigel, but I should also note that the star was only 25 degrees above the horizon for that test. So it's not like I was getting the steadiest pinpoint image to focus anyway - plus, the lens really hadn't had time to cool yet.

- Okay, next up, M45. When is this cluster NOT impressive? It looked wonderful with my 32mm Plossl, and actually had more "room" around the outside of the cluster than I'd expected this scope to have. Tight, yes, but not uncomfortably so.

- M31 and M32: Visible, of course. Bad position in the sky for me tonight though, so I didn't look for long.

- Capella, again to check CA, and because it was higher in the sky and had cleared the front yard tree. CA still there, but didn't look as bad now. There's some purpling around the outside, but really, for a scope like this (non-apo, and very reasonably priced), I really can't complain. The CA is not bad at all.

- Double Cluster: WOW. Awesome. Like someone sprinkled suger on a black tablecloth.

- Polaris: I could see Polaris and it's dim companion at 85x. Further easily split at 109x. Too dim to see well at 195x (and this is beyond the scope's highest recommended magnification of 182x anyway).

- M42 - I could see color! Previously, I'd only seen color in M42 in scopes of 4.5" or greater. I could definitely see bluish-green with the 32mm and 25mm eyepieces. At higher powers though, detail of the nebula increased, but I lost the color, and only saw grey. Trapezium was split even with the 32mm eyepiece at a mere 28x.

- Gamma Andromeda - split at 36x, nicer at 65x. "Green" component star seen next to yellow primary.

M35: Nice. Very nice.

A couple things:

- The tube is long. Even with the tube rings nearly at the point where the focuser meets the tube, I found that with the EQ mount and tripod that I used, I was uncomfortably low with the scope pointed at the zenith. I'll need to make some longer tripod legs. Probably needs a tripod that as at minimum 48" off the ground, and likely taller if you're at least 6 feet tall like me.

- The finder, I noticed when setting it up during the day, has a weird tendency for the crosshairs to "float" slightly as you hold your eye at the eyepiece. It's not horribly objectionable, but it is unusual. I didn't find it a problem when pointing the scope at night, but it is a very small finder, and really needs a larger one. One thing I will say about it though, is that it was VERY easy to align with the main scope; the "spring loaded" point with only TWO screws made aligning a snap.

- I was happy with the focuser. Granted, I've never owned a "really nice" focuser, but I found this one quite smooth and easy to pop objects into focus.

Overall, I'm darn glad I got one of these. It's a "two trip" set up for this scope - one to bring the scope out, and a second trip for eyepieces and a chair. No complaints about that, at all. I look forward to doing some more high power viewing, particularly on the Moon and some planets, but I can't see myself being overly disappointed, given the low cost. I'm already enjoying the heck out of it, and that's just on the DSO's I knew where to find without even consulting a star chart.

Definitely recommended: I hope Orion brings this scope back!!

On the page for the Sky Watcher it specifically stated that it was made by Synta. As for the mount I was looking at the AR-AZ model and this was an Alt-Az mount with dual slo-mo controls. Actually all of previously mentioned scopes were on Alt-Az mounts so I cannot comment on the Meade EQ-2

I just checked my email - Orion did respond to me. They said that they've discontinued the OTA only version, and are only selling the package of that scope with an EQ mount now.

Of course, as has been stated, lots of customers asking can have an effect. It won't hurt for more people to send a note to them asking for the OTA only to be stocked again. You never know - they might change their minds with enough feedback....

EDIT: Well, if this Skywatcher 90mm scope really is the same Synta scope as the Orion, that still looks to be a decent deal. I don't care for red-dot finders where I am, because I can't see any more stars without magnification. But the 6x26 that came with the Orion was pretty minimal anyway, and at least the Skywatcher comes with a 90 degree diagonal, and a mount that can be used until something else is purchased/built for it.

Great Report Magic!

Yes, the scope is really a great deal for the price but it does need a long set of tripod legs.


Do the other scopes mentioned above have multi-coated (greenish tint) objectives? If so then it's a reasonable assumption that they may be the same as the Orion. But if they have the purple/blue single coat then they may not be as good as the Orion objective.

Orion is still offering this scope but with a small GEM mount for $330. It would be great if they once again offer just the OTA for around $100.

Well I have no intention of buying it with a tripod, especially with an 80ED on the agenda. But if Orion were to cave to pressure and reintroduce the OTA, I'd probably pick one up some time in the next several months. So let's keep bugging them about it.

It was a mistake for Skywatcher to give you a 12mm plossl instead of a 9 or 10mm. The second complimentary eyepiece should never be half the focal length of the first one. If they fixed that problem then it'd be a magnificent deal.

I was pleasantly surprised with the 25mm and 10mm Sirius Plossls that came with this scope - I had several of these eyepieces back in the mid-1990's and they definitely were inferior to this pair.
The 25mm is very crisp and sharp, and the 10mm actually was slightly better than an old TV 10.5mm I had lying around. It does a great job on Jupiter in my TV102.
Together, those two eyepieces would cost you about $90, which is ten dollars less than I paid for the scope.

One more question about the scopes on Optics Planet...They don't mention any specifics about the focusers on the 90mm achros, at least not that I'm aware of. Might any of these low-budget refractors actually come with a 2" focuser? If so, I might be able to get away with one of them instead of the ED80 and end up paying less than the Mak sale, but I don't know how good the Meade and Celestron 90s are, nor how strong the mounts are.

That was a one time deal of overstock items. I didn't pick up the 90mm achro but I did pick up the overstock 130mm short tube reflector OTA for $72. It sold out quickly.

Well it was an awfully long one-time sale then. Several months AT LEAST.

At the very least we should be able to harass SkyWatcher into switching out the 12mm eyepiece for a 9-10mm one.

Hey it just occurred to me that at this strategically important time of the year maybe orion's strategy was to discontinue availability of the ota because they are afraid that it would take away sales from some of their more expensive scopes?????

Well you're probably not going to sell an OTA to a beginner unless s/he happens to already have a really strong mount and tripod. So any scope package for a beginner would have to be mounted. Maybe if they had an alt-az version of the Astroview 90 and made it available for only about $200 during holiday periods then they'd hit a niche. The OTA-only assembly is almost always bought as a second scope, though - in this case as a grab-n-go. And I guess they assume that anyone who already owns a mount isn't gonna be interested in a small achromatic refractor....um, right? Well WE can attest to them being wrong, but they probably don't realize that yet. Which is why our screaming is important, because a quality 90mm OTA-only refractor like that is such a nifty thing when you're traveling and don't want to have $1000 riding around in your trunk.

If they bring it back I will definitely buy one, even if not immediately.

I did point out to them in my email the second scope/ grab n go point that you raised. In the book Astronomy Hacks the author even suggests buying the scope with the eq mount, selling the eq mount on astromart or cn, and then buying an alt az mount.

At that price point the mount would cost more than the scope.

Question...as u can see from my sig I have a SV M1 with gng tripod that is used with my SV 80mm f/7 Aplanat...would this mount and tripod work for the orion 90mm f/10?

Thanks

Orion had two overstock OTAs. The 130mm short tube reflector sold out quickly because of the exceptional optics and price. The 90mm achro didn't get much buzz on the refractor forum. Many months ago, I remember reading one thread about the availability of the OTA but hardly anyone reacted to the post. So, it doesn't surprise me that the 90mm took months to sell off.

The key thing is that if you see a good deal you need to jump on it. Case in point is the closeout sale of the Celestron 80ED refractor over a year ago. I missed out on the sale and had to buy a used one. The price was pretty insane.

Thanks Preston, and yes, longer legs is a project I’ll have to work on soon.

Karl, the one thing they do mention is that the diagonal and barlow are 1.25”. My guess is that if it were a 2” focuser, it would say so. On the bright side, by my (perhaps conservative) estimation, a person could purchase that Skywatcher set up and sell the tripod / 12mm eyepiece / red dot finder / barlow, and come out with an effective OTA price of around… $130. Just a thought.

Also, the Skywatcher USA site I listed on the previous page indicates a $170 scope price, although some of the included items seem to vary within the description (finder, diagonal, etc.). That'd be one way to save another $20 on it...??

I ordered the Skywatcher 90mm f/10 with the alt-azimuth mount a few weeks ago. I bought it thinking of my kids. I've only had one opportunity to use it.

One thing I will note is that it came with the 45 degree prism diagonal not the 90 degree diagonal.

I won't report on the optics at this time because I haven't had enough chance to use it except to say that there were no obvious optical problems when I used it on the Moon and quite a few different types of deep sky objects. I was pleasantly surprised by how much detail it revealed on M-42.

The mount is decent. When you operate the slow motion contr0ls it is very smooth. There are some vibrations but they were greatly reduced with celestron anti-vibration pads. The only real problem I found was that there is quite a bit of backlash when adjusting the altitude manually (not when using the slow motion controls).

A few other notes regarding the skywatcher version. The objective is multi-coated and the focuser is a 1.25" focuser. I bought a williams optics 1.25" dielectric diagonal for it.

The one night I used it I tried the 25mm plossl that came with it, a 20mm Pentax XW, and a 14.5mm Orion edge on. I did not yet try the barlow or 12mm eyepiece that came with it.

In the 90's I had owned the orion version of this scope and had purchased a 1.25" to 2" adapter in order to use 2" eyepieces with it. So I picked up a 1.25" to 2" adapter for this one but none of my 2" eyepieces would focus with it -- just not enough infocus.

I just got an answer back from Orion. Maybe we are having an impact and they are changing their tune:

Thank you for contacting Orion.

Unfortunately we are currently out of stock on that item due to the popularity, however I do not know when we will get them in stock.

I will let our purchasers know that there is so much interest in this item, as the wishes of the customers is what drives our product line.



So, if you want to purchase this OTA - send an email!

BTW: Love the syntax.....

Could anyone tell me if the orion 90mm f/10 ota would work well with my Stellarvue M1 altaz mount on the stellarvue grab n go tripod, just in case the ota should once again become available?

thanks

Hi Bryan,

I have the M1 mount and the 90mm Orion. I personally think the scope will be too long for the M1 but I will try it out for a few minutes tonight and let you know how it goes.

Well I just put my two cents in and sent Orion an e-mail about this scope. If it does come back I fully intend on buying two, one for me and one for my six year old daughter.

Just tried it out. If you have the M1 mounted on a very solid/stable tripod AND you have the MECA column extender then it should work. Just be prepared to adjust the balance often when you are changing out eyepieces as the M1 is performing near its limits with this long scope. If your tripod isn't a high one then you may want to have a chair when you are observing toward the Zenith.

I almost feel like creating several e-mail accounts so that I can pose as multiple people when talking to Orion about recontinuing the Nifty Ninety, but I don't think that will be necessary. This may be one of the times when protesters are actually able to affect change in the world!

Luckily I was able to find an alternate source for one. I think I'll amend my refractor plans a little and start with the 90 f/10, then upgrade to an 80ED some time soon if I feel there's a benefit to doing so. Another option would be to keep the Nifty Ninety and add a 120ST for wide fields and DSOs, though I'd probably want to upgrade my mount if I plan to do that.

I rec'd the reply from Orion in less than 48 hours, today at 11:26 a.m. stating exactly the same as others here reported. It's discontinued, not sure whether it will be ever carried again, but "Patrick, Orion Customer Service" will pass the info re the interest to others.

Really, who knows, maybe we succeed in keeping this achro around for a little bit longer. At least it is worth a try. If not, oh well, as some here said, SW version is still a good deal.

I will say one strange thing about this scope in regards to CA: It's varies with the target, and not necessarily in order of brightness.

For example, I just went outside for a look at Jupiter and the Moon. Jupiter looked decent, but still the "purple fringe" around the limb of the planet at 182x. Yet, same eyepiece, same barlow, there was almost NO discernable CA on the limb of the Moon - and it really was dark out, so the contrast definitely was there to see any CA issues. I saw a HINT - no more, no less - of yellowing along the inside (lit) edge of the Moon, and NO purpling outside. Yet when I wheeled back down to Jupiter, there was the purple haze around the limb again!!

I keep intentionally looking for the CA in this scope - I know it's bad in my little ST-80, but I don't use that scope for planet/lunar viewing. But this is my "new grab-n-go" scope at the moment, and I'm really trying to push it to see what the WORST the CA is going to be. And although there's the issues with Jupiter, I didn't have CA issues with the Moon to speak of.

I'm having trouble finding things to dislike about this scope. A little bit of fringing on Jupiter and the very brightest stars is really not much to complain about - especially given the price (assuming Orion brings it back).

Just thought I'd update everyone on that.

Has anyone tried the 90 out at 200x or slightly higher to see what its optical limit really is?

I had the 90mm skywatcher on the Moon at ~200x the other night on the Moon and the image was very sharp with minimal CA.

I had a chance last night and then again this morning to use this scope. Seeing was terrible at times. Living in LA is a very hit and miss affair. But my new scope didn't fail me. Last night the views of the moon were awesome and Jupiter did not dissapoint. I could clearly see 4 bands on old Jup which surprised me and the detail on the Moon was very impressive.

This morning I spent about an hour viewing M42 and was pleasantly surprised at all of the nebulosity. The best views were with my 15mm Expanse eyepiece. Perfectly framed and very bright in the eyepiece. I then moved to Mars but seeing had taken a nose dive and could not make out any detail just a small round orange-red ball no matter which eyepiece I tried and would not come to a crisp focus.

In contrast to what Magic posted I did see some CA on the edge of the Moon but had to use averted vision to see it. So it was minimal at best. On Jupiter I did not observe any CA at all.

Karl, I could only get up to 181X using my 10mm + barlow as seeing was very bad. But it did handle it OK IMO. When I tried to use my 7.5mm + Barlow the image degraded too much.

So far this scope has not dissapointed me at all. There is not one thing that I dislike about it. I am even getting used to the finder that it came with. Please keep in mind that I have never looked through a "quality" scope. I am a budget minded newbie astronomer. So take my observations with a grain of salt. That said, I absolutley love this scope..... it easily competes with my 6" F/5 reflector as it is much easier to set up and use.

Another pleasant surprise is the eyepieces that came with this OTA. I am really enjoying both the 10mm and 25mm Plössls. When I purchased this scope I thought that I would get some bunk eyepieces with it but to my astonishment they are very good quality.

If Orion does discontinue this OTA it will be an injustice to the hobby.

I'll second that. I had two barlows in mine - both ahead of the diagonal (one was a "good" Meade barlow, the other a cheapie shorty barlow) - and then my 10mm Plossl. So this is a ridiculous amount of magnification for this scope - I don't think the shorty is a true 2x, so I'd estimate the magnification somewhere between 275x and 350x.

Well, it was a bear to get in focus - but that was a mount issue due to vibration. But I COULD focus the Moon. Incredible detail! Now, conversely, I couldn't get Jupiter to focus similarly, so I've had to look at it with lower magnifications, but I have gone higher on the Moon, and it has remained sharp, contrary to my expectations.

Don't forget that some of that can be from the atmospheric conditions. I'm not saying this scope doesn't have some CA just that it will vary depending on all the "lenses" you are looking through: The upper atmosphere, local sky, the objective, the eyepiece and of course, your peepers!

I would tend to agree with that assessment, Preston. I had a mental image of what the CA was like from a few days earlier using the barlow ahead of the diagonal, and it was definitely an increased CA presence a few days later. And I don't recall being able to get quite as sharp an image on my later observing session either, so it's certainly possible all those additional "atmospheric lenses" were playing a role in what I saw regarding CA.

I really should stress, that I've really been looking hard for CA in as many situations as possible. In truth, it just isn't all that bad - really, pretty darn minor overall. If ANY CA bothers you, well... you won't like the scope. But considering what I could see of the Pleiades (field-of-view-wise) in addition to the higher powers it managed on Jupiter/Luna, it's a great scope. I know I sound like a broken record, but I hope someone from Orion is reading this and decides to bring this OTA-only version back - I can't say enough good things about it, especially given the price.
