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....

John- I love this scope already, and I've only looked through it for a short time. I plan on buying the FR down the road, but in the mean time I'll continue my imaging efforts at f/10.

Good read. Thanks for the write up. I'm looking to purchase an EdgeHD 9.25 soon hopefully.

Jerry- Thanks! I plan on doing a more in depth review as I get more clear skies.

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

John- Hopefully you will have success guiding! My SV 80/9D is a wonderful guide scope when I use it with my TMB. But I think at 30 inches long, it might to long for the Edge. Though I could always give it a try.

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.

Patrick

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.

I got a 9.25 Edge OTA last summer strictly for visual. It won't disappoint.

Beautiful setup John. I'm using an IOptron iEQ45 with my Edge. Here's a picture from the first light night, after I stopped imaging. I really need a dew shield, luckily it will be here tomorrow.

here is my recently bought 8"Edge on a AVX mount, although I have now gone to a 2" diagonal since I took this pic

Great looking setup! I've heard a lot of good things about the AVX mount.

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

Thanks,
Steve
