You need to use a focal extender if you want to get the full resolution that a 12" should be capable of. Other than that, your image is processed nicely without over sharpening. Perhaps it can be brightened a bit more.
Your imaging was done at 3000mm and mine, also at prime focus, but at 6500mm focal length.
Last night the seeing was worse, so I did not bother.

Hi Stefan
Will eventually move on to a focal extender. Currently plan to use eyepiece projection as I have a Tele-extended and quality University Optics Orthoscopic eyepiece acquired back in the day when I was working for Binocular and Telescope Services Centre in Heidelberg and BINTEL in Camberwell. Did have a Televue 2x Powermate but sold it ages ago when I lost internet in astronomy because I worked in the industry. Probably wasn’t a good idea.
Cheers Anthony
