Tomorrow I'm heading to Spain to switch out my CGX for an ASA DDM85. I would not recommend the Celestron for long focal length setup, as the mount simply isn't good enough. I will bring it back and use it for my RASA @620mm, for which it is great, but definitely not for an 11".

YMMV

So you recon the EQ8 is better??

Its the whole length of the C11, and will be at the end of the tightener grips on the mount saddle...…...

Hi Olly, not sure of its RMS,  I also know someone that has some luck with the same set up. I image off axis anyway so that's ok. Ive recently upgraded to a moonlight focuser (more weight all at the eyepiece end) this includes a filter wheel, OAG, Lodestar x2, Atik 314 mono, ect…...another big issue is balance in DEC, im right at the end of the dovetail plate almost, that's without the focal reducer, meaning id have to add even more weight nearer the corrector plate area to balance it. I recon its pushing it somewhat...……….

Looking to upgrade my mount in the near future, and im thinking between these to, its for imaging through a Celestron C11 Edge HD with focal reducer. I currently have a Losmandy G11, which im fairly certain will be an issue when it comes to payload...……..

Field comparison between my William optics zenithstar 70ED...……….and my MN190 (focal length 1000mm)

Hi again so heres a pic taken the other night of the Cresent nebula NGC 6888, in h-alpha, through the Ascent 102ED, Varying exposures (16 in total from 2-8 mins) as I was hampered with fine layered cloud, which also affected the image. Its uncropped, to show the results with the field flattener I also got with it, and used. Camera was an Atik 314 mono, 7nm h-alpha filter. Guiding was off axis. Considering the focus was a bit of a rush, and being the first time off using the scope, theres room for improvement im sure.

A bit of an update on the scope, had first light last night and did some imaging in h-alpha of the cresent nebula, as soon as ive processed I will post here.  The scope is pretty good, the focuser held up very well, concidering it had the flattener, filter wheel, atik 314, off axis guider and lodestar x2! so far not bad...…….

Just brought one...………….will post more when I get to first light, give my 2 pence...……...

Id never be happy with an 8-10" newt at around F4............like all the above said, collimation, and the coma is to much for me these days, that's why I went for the MN190 (mak Newtonian).

The mount is almost a historic classic.......my friend has one, ive got a losmandy G11, but I still like the mk4.......any ideas what focal length/ratio the scope is?? Older scopes from yrs ago, can sometimes be longer.............much better visually especially on planets ect.........

Im loving these 1st attempts.

Thanks for the info....

There you have it then, reading all the comments hes a sound guy..........for me I do my own camera modding.
