Just in case anyone else wants this new OAG, OPT has plenty more in stock.

guided subs. Right now I get 60-90s max at 2032mm. Next on my list is new guiding camera. Then maybe a modified DSLR or CDD. Of course if I go the CCD route I'll get hyperstar as well. Astrophotography is a sickness.
Mike- Will do. Though the forecast for the next ten days is rain everyday. Hopefully I'll get a chance to test before to long.

Good luck with your imaging. The part that took me the longest was figuring out how to frame and focus everything. Do you use a guide scope now? Have you used a OAG before? And what guide camera are you going to use?
I'm curious as to whether celestrons included adapters will let you reach focus with the guide cam and your imaging cam at the same time. Seems promising looking at the list of included adapters.

Yeah it took me awhile to understand the framing and focus part, but luckily BYEOS makes this much easier. I don't use any guide scope when imaging with my Edge 8. Because of that I've been limited to really short exposures. When imaging with my TMB I use a guide scope and have had really good results with it.
This will be my first experience using an OAG, so I'm not sure what to expect. I use a SSAG, but I've heard it's not sensitive enough to use with an OAG. Hopefully that is not the case, because a new autoguider is not the budget right now.

Congrats on the new OAG! Mine (Orion, not Celestron) worked like a charm on my 8" and 10" SCTs.
Get ready for the skies to clear... I'm going to send my camera out for modding and I'm sure the skies will be pristine while its gone!
(Shhh, I'm hiding a second camera under my scope...)

Thanks! I'm hoping it works well with my SSAG. If it doesn't, well I guess I'll have to find something else. Haha. Of course the skies will clear as soon as your camera gets sent out. Then that will give me
Enough time to try out my OAG.

The reasons I'm hoping this is good for me is that I really don't want to deal with trying to optimize the back focus distance on my 11" EdgeHD scope. My impression is that this one comes with the proper adapters and what not to make the distance to camera sensor appropriate for my system. Clearly there are other ways of making this work, but I'd like a system to work "out of the box".
I'm going to be away from my telescope until early August, but I'll be focusing all my attention on getting this to work when I return.
I would imagine that by the end of August there will be several reports here that will let people know if this is a good OAG setup or not without much leaping involved.

I know many are excited about the OAG, but why? I'm in the market, and not sure what makes one great? I know sturdy is a factor as well as thickness. I was looking at the TS9 or the Olivian? copy.
I choose it because it looks to be matched to the Edge line of scopes and its price did not break the bank.

So I think a good one makes a difference - and some of them really do cost a lot. I haven't tried this one.

David- Of course of course! Though everyday for the next ten days has 40-50% chance of rain forecasted. It's supposed to arrive Tuesday. I'm hoping I'll get some clear skies later in the week to test it out.

The main reason I bought this system was to have an OAG that had the proper back focus for my canon out of the box rather than having to make compromises or purchasing a large number of adapters from third parties. On that front this is certainly a success. For people who have limited back focus distance available to them this is NOT going to be a good OAG to buy. It will also probably be difficult to work with filter wheels. But in my case with a Canon 60Da as the imaging camera and using Astronomic EOS clip in filters, it may be just about perfect.
Of course, all of this is meaningless unless the pictures come out looking good. Unfortunately tonight is the only night I have to test it before going out of town for three weeks... If I have the opportunity to do a first light, I'll post back here again.

I agree that this system seems is robust. Plus it comes with a whole slew of adapters. I'm hoping for first light tomorrow night with my Edge 8, T1I, and SSAG.

I'll be using this on an Edge 11, Canon 60Da and SSAG. The mount gave me problems just at the point where I had achieved focus in both the guider and camera... the fun was about to begin and now this. Oh well.
Good luck on your end!! It has to be better luck than mine!
By the way, I think there is an error in the manual that comes with the guider. If you look at the figure for setting up with an Edge 8 vs. an Edge 11, the suggested adapters are identical even though the suggested back focus is different. I confirmed that the figure for my Edge 11 gave the proper back focus distance, but you might want to actually measure the setup you get with your 8 because to me it looks like if you use their suggestion you are going to be too long and will want to use one of the shorter spacers.
