Large aperture (12") , no CA (mirrors+correctors), fast F3.8 and thermally stable.
I can't wait to see what you capture with it.
Again congratulations

The problem is while the scope is a superb astrograph the Keller Wynn corrector is designed to be hard attached via screws to a filterwheel and has a set back focus ie no eyepiece adapter etc. The corrector does simply slips out of the 3" focuser though and a 2" adapter slides in to take 2" eyepieces, barlows or coma correctors etc.
I imagine an adapter could be constructed to allow eyepieces to be held in front of the Keller corrector but that is out of my manufacturing capabilities at this stage I'm affraid.
I will try it out visually with the Keller corrector removed and see if I will need another smaller coma corrector or not.
Cheers mate
