Now I'm looking for a worthy scope to put atop this magnificent mount, one that gives me a combination of great optical viewing along with DSO imaging capabilities. I've not seen any comments from people who have paired the Mach1GTO with an EdgeHD 11 although it seems like a great combination to me. The mount is conservatively rated at 45 lbs and the Edge HD 11 weighs in at 28 lbs leaving room for camera, guide scope and accessories. It seems like I'm able to have it all: DSO imaging with HyperStar, great optical viewing, planetary imaging at the longer focal length and even relative portability. The only drawback I see is the limited imaging footprint in front of the Hyperstar assembly but I could also use the now available focal reducer. It seems like a very versatile setup but not having seen a single comment mentioning this mount and scope combo makes a me a little wary. Am I missing something?

I mostly use an STF-8300 pro+ package which includes off axis guider and filter wheel. I am sure that you could get good results with the Mach1GTO with an off axis guider. I have done imaging at the native 2800mm and with the price .7 focal reducer (1980mm). I hope to purchase a hyper lens this summer to use with my Canon 6d for wide field at f2. I know one other imager locally who is imaging with the C8 EdgeHD on the Mach1GTO and he gets great results.

I am not familiar with the Celestron 11" But i guess it would be similar in size to the 10"RC. My OTA fully equipped for AP weighs in at ~38lb. The Mach1 with this setup performs very well to the point that I stopped using my less portable NJP. I hope this info is helpful.

I have a C9.25 which only weighs 5lb less than the EDGE 9.25. At native focal length, and not even using an OAG, I get 100% keepers at 10 minutes. 20 minutes, not 100%. Last night I tried using the C9.25 with a 2X barlow, giving a focal length of... 5000mm. At that FL, with my guide scope, and with 6 minute subs, I only had 30% keeper rate. Definitely 5000mm is a bit too much for the Mach1.. maybe an OAG would give better results, but given that it still produced usable subs with a separate guide scope at that FL, I would not hesitate to put a C11 on it.

I have 46.5lbs of counter weights on the mach 1, guided with a st80 and a qhy5l-ii, I am only shooting 10min subs tonight and my guiding rms in phd is .23 at a 1.93 arc sec image scale with the guider. I will see how many keepers I will have tomorrow though, hopefully all of them. Once I get an oag I am planning on longer subs, 20min or more. I guess to answer your question, mine can handle my 10" without breaking a sweat.

I'm definitely doing the Edge 11 with the Mach1 mount now and look forward to posting my first light photos here. Many thanks y'all.

He implied it could handle a lot more then it's rated for.

I just finished testing the 10"RC with the CCDT67. With OAG i was getting about .25"rms round stars at 10min subs. Orly I don't think any mount would allow you to shoot at 5000mm without an OAG. My guess is that differential flexure would be a nightmare.

Some part of me wonders if they don't want it to be too close to the 900. I have heard anecdotal stories of people running it with up 100 lb for visual.

So you cannot say 5000mm was really too much for the Mach1.

That is exactly the point that I was trying to make:) Post Extras:       orlyandico Carpal Tunnel Reged: 08/10/09 Loc: Singapore Re: AP Mach1GTO Mount paired with an EdgeHD 11" [Re: andysea]       #5713666 - 03/05/13 12:09 AM Edit   Reply   Quote Quick Reply   The Mach1's gears are the same size as those on the NJP. The NJP is 70lb rated if I recall correctly.. but with Taks you have to derate (a little bit). Note that Jerry Lodriguss considers the EM200 (40lb capacity) overloaded with the C11. So the NJP should be good for maybe 60lb imaging. If we follow the reasoning that "same gear size equals same payload" then the Mach1 should be good for 60lb as well... if the OTA is short and you have a monster pier. I wouldn't want to do that though... IME when you push a mount to its limits it becomes less consistent. With c.a. 35lb of payload I don't have to care about mundane things like balance...

All I know is that even with a mount rated at 60 or 70lb....I am definitely not going to carry a 60~70lb. imaging rig to a dark site:) Post Extras:       Wembley2000 super member Reged: 01/07/12 Loc: NW Ohio Re: AP Mach1GTO Mount paired with an EdgeHD 11" [Re: andysea]       #5713953 - 03/05/13 07:45 AM Edit   Reply   Quote Quick Reply   I ended up doing 15min subs the other night with the Mach1, 10" Meade sct at 1965mm focal length, and 46.5lbs of counterweights. 25 out of 25 keepers, there was some flexure and I need to recolimate, as I had some flaring to one side. I was very happy with the results, now I just need to get my new celestron oag which I have on preorder. Brian Post Extras:       CounterWeight Postmaster Reged: 10/05/08 Loc: Cloudyopolis, OR.

TEC APO160ED with Orion ED80T -CF piggyback, SBIG 8300M/FW8. This setup has a much longer moment and works flawlessly. Not just bragging or speculating - here is some proof.

Nebula Re: AP Mach1GTO Mount paired with an EdgeHD 11" [Re: galael]       #5714952 - 03/05/13 05:35 PM Edit   Reply   Quote Quick Reply   I used a C-11A on my Mach 1 for a long time and it's a wonderful combination. I had to let mine go because of back issues, but those have now been fixed with surgery. I talked to Roland at NEAF a few years ago and he told me the Mach 1 could easily handle a C-14 for visual observing. I have seen them loaded up with 60 pounds worth of refractors and there were no issues at all. My Mach 1 has performed flawlessy for almost four years and it can easily handle any scope I wish to use.
