First Light for Edge 8''
      #5713378 - 03/04/13 09:12 PM

This might be my favorite scope I've owned of all time or at least a very close tie with the TMB. I put the scope outside to cool at 5:45 PM EST and started viewing at 8:00 PM. This seemed to be plenty of time to cool down. I had a peak at Jupiter with the 10 Ethos, and wow did Jupiter look great. Going off memory the view through the Edge is better than the view through my TMB, but the actual comparison will have to wait a while. The Orion Nebula looked fantastic. I'm currently imaging it, but I'm limited to really short subs because my polar alignment was not perfect and I'm not guiding. I'm hoping the clouds hold off long enough for me to view Saturn.

So far so good. The Edge series scopes have me hooked. Now its time to buy a 14 and an AP900.

David- It is an excellent scope so far, but the clouds stopped me from waiting for Saturn to rise. The next clear night is looking to be Thursday after this storm blows through. The AP900 is a dream mount of sorts. Once I get working and settled in again there's a good chance one will be purchased.

Warren- I was having a blast until the clouds decided to ruin my party.

On a side note I could not get the mount to balance in the DEC. Is there some sort of trick to balancing an SCT in the DEC axis. The scope is back heavy as one would expect. Maybe I need to buy weights for the front of the tube?

Sedat- Thanks! Not only are clouds on the way, but a snow storm. It's alright, I should get back under the stars Thursday or Friday evening. Which gives me plenty of time to figure out the balance issue.

That's great new's, after having owned many scope's but not a TMB well maybe the AT111EDT which was a TMB designed triplet and many Russian MCT's plus a bunch of standard SCT's I have settled with the 8HD myself. The images have been some of the best I have seen and finally now just one scope that I use the most. Have never had one observing outing that the did not please me except for seeing conditions which I have no control over. Would love to see your pic threw the new scope.
Enjoy
Jim

I am not surprised to hear this from someone that likes refractors.

The EdgeHD 8" is the only SCT I have owned that matches the off-axis performance of the best refractors I have used.

100% equivilent.

For people that have used refractors and developed an appreciation for pinpoint stars across the field, and believe that it cannot be the same with any other kind of scope, the EdgeHD 8" is a lesson in telescope design that is hard to ignore.

Much of the refractor bragging is due to the fact that off axis, the performance is much better than with most reflectors (not all.. The MNs and Intes f/10 MCTs correct for coma as well, and both offer flat fields).

The EdgeHD 8" design moves the scope into the same catagory.

It is such a pleasure to use the EdgeHD 8".

I was out binoviewing some large clusters a few nights ago in the EdgeHD 8" with some 24mm Hyperions.

What a fantastic view. Brilliant right to the edges.

100% as good as my 6" APO. I rarely use that scope now. Only when I need 2 degrees (Milky Way scanning).

Enjoy your EdgeHD 8" and do share a followup review when you have had more time to enjoy it.

We just discussed this in regards to a C8HD on the mounts group here: http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/5708635/page...

It helps to add a little weight to the front of the scope, especially if you add an imaging train on the back and it can be done in a couple different ways.

Wow, you must have had good Karma to have good skies first out there AND to be able to use 200x on Jupiter. Most nights I can't get pass 160x!

Good luck with your new scope and look forward to more of your posts with it:)

Jim- Thanks! I'll post a link to the picture at the end of the post.

Ed M.- It really is a great scope. I plan on doing a full review of the scope when time permits, as well as side by side review of the Edge against the TMB.

Ed T.- I think this will do the trick. The adm option seems to be cheaper than the scopestuff options. I could always attach a larger magnet, it would not aesthetically pleasing, but should do the trick. Is there is harm in attached a magnetic weight to the end of the tube? The black part and not the nice Celestron paint.

Bob- Yeah I was quite lucky to be use my 10 Ethos for a little while before the clouds rolled in. Plus I think some of the smoke from my neighbors wood burner added to the sky haze towards the end of the night.

Here is a link to the picture: http://www.astrobin.com/34903/#

It's 34, 15s subs and 20 darks at ISO3200 taken through a Canon T1i. My focus looks close which was aided greatly by a Bahtinov mask. I wish I could push unguided subs longer. With a better balance and better polar alignment I probably could.

The Edge tubes and front and rear cells are aluminum, so a magnet won't work.

I might be able to make my own counter weight system using a 1/4-20 bolt and some homemade counter weights. I made lead counter weights before and it was difficult.

You may be over-thinking this.

It is not at all essential that the scope be perfectly balanced in Dec. The motors in almost all scopes are geared down and have so much excess torque that they can often drive an extremely out of balance load with on real strain.

If you slew the scope using the hand set and the motors don't sound like they are excessively loaded, then I would not worry about it.

Interesting to read this....It is always a struggle to find perfect balance at all points in the sky ....and then when changing from say an ep weighing 1lb to one of 0.5lb then that perfect balance is lost.....

I have often wondered really how critical perfect balance really is.....
So, Edd as long as the scope doesn't rapidly tip when the Dec clutch is released and the motors are not making any real straining sounds when slewing and tracking/gotos are good should I not worry about finding "perfect balance"

I use the new Skywatcher az eq6 mount in alt/az mode and a CGE PRO Gem.

Thanks for your input Ed. When I release the dec clutch there is rapid tipping of the scope. Though I don't remember the motors causing to much of a stir last night. None the less I'm going to attempt to make some weights out of lead. I tried 30 2in washers plus 5 oz of stick one weights used for soap box cars and this was not enough weight, though it did help a little.

Well, understand that this is just an opinion, but I have run every mount I own out of balance just about all the time.

If the motors are not straining, there really should not be any harm.

Perhaps over several thousand hours, a lot of pressure on the worm might wear it prematurely, but running a few pounds out of balance for an hour or two is sooo not going to hurt anything...

Thanks for the info Ed. I had around two lbs. of washers and a magnet at the front the tube. Even then the scope was not balanced. I'm guessing it would take another .5-1.5 lbs. to balancing the scope.

It's actually not usually an issue of damage to be done by running out of balance but an issue of impacting performance and it depends largely on the mount and its quality in the first place. Absolute perfect balance is generally not necessary and in DEC is not desireable since perfect balance in DEC will result in the mount head bouncing back and forth in the backlash between the worm and the ring gear. I high capacity, good quality mount will not notice imbalance much. But a lower capacity, lower quality mount may perform poorly when signficantly out of balance. That tends to be a problem in the CGEM/ATlas/EQ6 level mounts and below where the axes are often stiff to start with and very difficult to balance properly. A G11 may or may not fall into this category, but they are usually fairly easy to balance. A CGE will generally run better when well balanced but is not terrible when not, but then the CGE is usually fairly easy to balance in the first place. Once you get above this level of mount, balance may be less critical to good performance, but the mounts are often easier to balance in the first place.

If it is damage you are worried about, then the mounts will metal worms and spur gears will not be a problem. If it is performance you are worried about, then good balance is always a good idea.

In regards to the balance of an SCT in DEC, for me it is mostly a matter of not wanting the scope to be all the way back on the end of the dovetail where it is harder to balance and generally not very convenient. When you add heavy imaging gear on the back, you can simply run out of room to move the scope up in the saddle any futher.

Honestly, the Edge8 is just a fantastic scope. I've had mine for about a month, and I never tire of looking thru it-- and this is coming from a "refractor guy". I'm waiting for the FR to ship before doing some serious imaging with it later in the spring. Now I'm wondering what I'll be looking thru when imaging? I know, an Edge11....

How do you guide at F10? I'm hoping that my guiding rig will work at 1400mm-- I just assumed it wouldn't at 2000mm-- so I haven't given it a shot yet. My rig is a QHY5 with a small scope (50mm) held by beefy ADM rings attached to a dovetail bar on top of the Edge8. In the back of my mind I have the feeling I'll have to go the OAG route. I did purchase a FeatherTouch micro focuser for scope and it work beautifully.

With my WO66/SSAG, I've been able to guide my Edge HD 800 up to 8m. After that, there is some drift that becomes too much. I believe it is flexure from either my mounting or focuser. I have heard of people guiding at 5:1 with the Orion 50mm package, but I don't know about at 2032mm. Based on my experiences, I was surprised that people were able to get good exposures when pushing the 5:1. I hate being right at the maximum, and the F10 will be well over.

Last night I finally got my OAG working. This is after much struggle, but now I'm reasdy for the big league. I cannot wait until I get to image with it for the first time.

Adam- Thanks for your input. I still deciding between a small scope or an OAG for guiding. Though I'm leaning more toward the OAG. Currently it seems like a better route to take. I would try to guide with my SV 80/9D atop of the Edge, but I'm pretty sure that's way to long of a scope to be mounted on top of the Edge.

I'm about to try guiding my Edge 8 @ f/10 with a ST-80 and a QHY5-II guider. I tried a couple nights ago but had a problem with conecting to my mount. But I think I have that fixed and will try again tomorrow as it should be a clear night. My ST-80 is mounted with ADM rings and dovetail. I hope it will be sturdy enough to prevent detrimental flex! Of course, I'll also lock the mirror down while guiding...John

I find it interesting how many new EdgeHD owners are out there as I'm one of them, too...

I purchased mine in December and have yet to take the first image through it for one reason or another. Right now it's just the weather.

I have my AT66ED sitting on the C8HD with an ADM MDS dovetail bar and ADM rings. I think guiding the C8HD at f/10 through the 400mm refractor will be okay with my DSLR and short exposures. I also have the focal reducer on back order at Adorama...it sure would be nice if Celestron would release those soon.

I'm looking forward to imaging with the scope. It's a great scope to look through, too! I need to pick up some kind of grab and go alt/az mount for it.

Yeah there are a surprising number of EdgeHD owners. More than I thought. I plan on getting the focal reducer eventually, but for now I'm going to see how well I can image at f/10.

I have Universal Astronomics Macrostar Delux on a surveyors tripod. I really like this mount and can use it will all the scopes I currently have. I had the 8" HD on there the other day and the mount handled it well. I didn't get to test it under the stars, but I see no reason for the mount now to perform well.

Here is the setup I'll be using. It's on a Losmandy G11 mount...John




John, how is your guide scope mounting plate attached to the OTA? I need to get something similar for mine.

Thanks,
Steve

Hi Steve,

The scope and rings (ADM) are attached to an ADM V (Vixen style) series attachment bar that uses radius blocks to pick up existing holes in the Edge front and rear castings. The part number is VC8 on the ADM website. It is made to fit the Celestron C8 scopes and comes with the radius blocks and mounting screws. I love the ADM hardware. It is solid and beautifully machined stuff...John

I almost have the scope balanced in the DEC. I have a 5in bolt on the end of the dovetail with 2.8 lbs of washers. With this weight, plus the weight of the dew sheild I'm balanced with my 2in diagonal. I still need a little more weight to balance once the camera is attached to the scope. I don't have any room left on the bolt for more washers. I'll either have to get a 5.5in bolt or get heavy washers. At least I'm getting close.

Thanks very much, John. Indeed, ADM makes nice stuff.

Another great night with the Edge. I really love this scope. I've never seen so much detail on Jupiter. It looked amazing. The Orion Nebla looked wonderful as well. I also looked at M67, M68, M81, and M82. All looked nice, even in my light polluted skies. I really need to get this scope under darker skies.

The only issue of the night was dew. Even with a dew shield the corrector started to dew around 12:30 AM. The scope had been outside for well over 4 hours at this point. I guess I'll need to buy some dew straps. However in the mean time is a hair dryer enough to keep the dew away? Will it hurt the corrector to blow some warm air over it to prevent the dew from forming?

Zach,

Here is what I got last night on M51. This is a stack of 15 x 3minute subs. Guding was a BEAR! It is very difficult to guide at 2032mm focal length. I was able to get really round stars at 2 minute subs, at 3 minutes they were starting to trail just a bit, and 5 minute subs were not acceptable. I don't know if I had some flexure, or I just need to tweak PHD settings better. I could not get the RMS value in PHD to get below .25 and the OSC index was always low. 5 minutes is my goal for guiding. I will try some more. This was a fast processing job with a few darks but no flats. Anyway, it's just an example shot and I have a ways to go. But this longer focal length really gets in close and I like that!...John

John,
That's a great image. I do like how the longer focal length gets you a zoomed in image. I'm hoping once I get an OAG I can get 2-3 minute subs.

This image of M42 was comprised of 55, 20 second subs at ISO3200. I had a couple good unguided subs at 45 seconds, but I figured I better stay with shorter subs since the keeper rate was 92%.

When I tell people on the refractor forum that the EdgeHD 8" is on par with my 6" APO for field sharpness, I think they believe I am overstating the situation.

As you appear to be learning, the EdgeHD 8" is a remarkable little telescope.

It really is. It's a hidden gem. I love it.

Awesome Zach! I think if I ever get another telescope, it will have to be an Edge. Yep, sounds like time for a heater strip. Blow driers are a hassle and it really is better to be proactive when it comes to moisture on the lens .....Phil

Phil- Yeah I imagine the dew heater strip is the better way to go, though in the mean time the hair dryer will have to do.
