Hi,

I will use this refractor primarily for Astrophotograpy. I need some assistance on selecting one of these two scopes.

$1,599.95 Orion 120 ED OTA
http://www.telescope...roduct_id=09976
or
$1,599.00 William Optics Megrez 110 ED
http://www.buytelesc...p?t=1&pid=13517[/b]

The Orion 120 ED doesn't come with any "extras", however it does have the Larger Aperture with ED FPL-53 glass. F/7.5

The WO 110 ED comes with smaller Aperture (objective made out of Japanese Extra Low Dispersion glass) and lots of "extras". Comes with an Aluminum Carrying Case, 28mm EP, 2" Dielectric Diagonal, "Felt Lined" Mounting Rings, and "very smooth integrated dual speed microfocuser". F/5.95

Please explain why you feel one is better than the other...or just vote because you like one over the other.

Thank you!

DD

Man thats a tough call!!! The orion is sure to have great optics but they arent all that great mechanicaly and like you said no extras. I bet the megrez is a fine ap scope tho and it does have the extras to. But the orion is 120 mm and if the opticals are like the other orion ed scopes it will be an awesome imager. I wish I had such a tough decision to make!!!

Mechanically the WO scope is the way to go I would guess. Not sure if the glass quality is similar between the scopes, but 10mm objective and fl difference isnt that much to differentiate between the two IMHO.

I would go with the WO. William Optics quality is top notch. I owned the megrez 110 for about 2 months. It was a great scope. Very compact, and the mechanics on the scope were amazing. I foolishly sold it because I wanted to try an SCT. If I could go back I would have kept this wonderful scope.

I'd go with Megrez 110. I've used it a couple of times and it's very compact, probably a better grab and go than EON 120.

The Megrez has the mechanics to handle astrophotography - sturdy dual speed focuser and such. The Orion lacks these qualities and is mechanically not as well-equipped for astrophotography. If you're primarily interested in wide-field photography, I'd definitely go with the Megrez.

I'd lean towards the WO because of its mechanical superiority but would not discount the Orion due to the excellent optical quality of that 'scope.

If you can find an extra $400, you could buy the EON 120. A truly superb Synta doublet objective and excellent mechanical fit and finish (CNC OTA, sliding dewshield, very good dual-speed Crayford focuser).

I have been getting some AP time with mine recently and am extremely happy with the results. High contrast, completely flat field, pinpoint stars and virtually no in-focus CA.

As previously stated, the WO is much better mechanically, but the Orion has about twice the color correction as the Megrez does. The Megrez is actually a semi-Apo whereas the Orion is right on the borderline of having Apo color correction. Given the advantage in CA plus another 10mm of aperture if it was me I would much rather have the Orion 120ED.

Wellllll, I've got both of those but haven't tried any imaging (or plan to) with either.

For CCD imaging, the Megrez would likely show more c.a., especially around brighter stars. Appropriate filtration (or image processing) could clean that up.
The ED120 has a flatter FOV. William Optics does make a field flattener for the Megrez, so that would be a good accessory.
I've seen some really nice images taken with the 110ED.
Mechanically, it seems better suited to that purpose.

Flip a coin... :shrug: :lol:

There is a 'deal with the WO that also includes a FR. Another consideration is the size/weight of the OTA and the mount needed for AP. The 120 is considerably longer and possibly heavier with a narrower FOV (900mm vs 600mm FL without FR). Wide FOV is what AP is about with refractors (usually).

Mounting rings would add about $130+ to the cost of the 120. Plus a good focuser which is required for ease of AP if desired.

Ok, let's review:

WO Megrez 110 ED = 4 Votes
Orion 120ED = 1 Vote
Undecided = 3 Votes
EON 120ED = 1 Vote

Then I saw this thread:
http://www.cloudynig.../Number/2377988

And now I am looking at the EON 120ED. This seems to be everything the Orion 120ED is missing.

So the big question now...will it be the WO Megrez 110 ED, or the EON 120ED...its going to hurt, I mean cost a little more...

*BLEEP* all these choices!

You'll buy your new 'scope, whichever one it is, then obsess and fret over every last little thing, real or imaginary. Eventually, as always, you'll realise that any 'scope is better than no 'scope. :)

There'll always be people willing to queue-up and pay to tell you why whatever 'scope you bought was the wrong one. Forget them and just enjoy the darn thing! :)

The EON 120ED does look good, but I would like to see a review or two with some images taken first.

Here is a review written (Video, with Imaging Results) about the Orion 120ED:
http://www.andysshot....com/120ed.html
http://www.andysshot...om/120ed_2.html

Of course this review is aimed at the EON 120ED's predecessor. It sure looks like the EON 120ED is made of higher quality than the Orion 120ED. My hopes are the EON 120ED will perform at least as well as the Orion 120ED.

If you can afford the $1,995 price tag of the Orion EON 120ED, how about considering the Astro-Tech AT111EDT f7 Triplet?

The EON 120 has the good points of the 120ED (superb FPL-53 doublet optics) without the weak points of the 120ED (lower quality construction, etc). Kind of hard to go wrong with an EON, really, as it's the best of both worlds.

I looked through three of Skywatch 120 EDs which is same as Orion 120 ED.
All of them was excellent optically and didn't show that much CA.
I found that the craford focuser on ED 120 isn't bad actually quite good. It might not do good for heavy CCD or camera or 31mm Nagler etc but it was fine for panoptics and short FL Naglers. The movement was quite smooth so that it didn't show that much vibration while focusing as well.

If you need a better focuser, you can upgrade the ED craford focuser to something better like a feather touch focuser.

Does anyone own the Astro-Tech AT111EDT f7 Triplet? Care to comment?
How about a shootout between EON120 and AT111EDT?!!!

another vote for the eon 120- i miss my fpl-53 glass 80mm- so... as soon as the next income tax return season rolls around im getting the 120mm eon- unless of course a 6"-ish version is being sold by then ;)

I Purchased the Mergez 110 I plan to use for imaging. I know that the colour correction could be better. IF you are very careful with the focusing the colour most of the time is negligble in my opinion visually.

I could have purchased a different one with better optics. I paid 1398 that included the field flattner and rings.

I think that the price reflects excellent value for the money.

I have seen plenty of nice images taken with this scope and until My abilities can exceed the scope and I get serious about imaging.

I will be happy with the scope.I think the WO 110 is an afordable entry level scope for imaging. If money wasnt a problem and if WO had one in stock then I may have went with WO 110 FLT.

When I find the scope is the limiting factor then at that point I will upgrade to a better product.

I have had one since 3/20/08, but due to contant clouds and poor skies have not been able to get much time under the stars.

From what I've seen so far I think I will be very happy.

Dennis(denjo) has done some AP, this is one thread here

I second that. :ubetcha:
For visual use, the single-speed Crayford works very well.

Wait'll you try the dual-speed Crayford focuser on the Equinox/EON! Even though some of them require minor tweaking out of the box, when it's done they are very nice. Not far off MoonLite and Feather Touch nice. Not quite up there, but getting darn close, which is fantastic, especially in view of the price.

I've viewed through both, the 110 ED several times now.

If you are keeping the 8-inch celestron that you can use on planets then definitely go for the 110, it is much more portable and durable definitely still in the grab and go category and will compliment the 8-inch scope with wide field views.
