Martin,
Thanks for your comments. My scope was primarily built for visual purposes about 19 years ago but has since been configured for astrophotography and has recently found permanency in my backyard ROR observatory (built during the pandemic).
Specs as follows:
OTA Custom 256mm Aluminised O'Hara Primary Mirror
F5 1250mm Newtonian (hand ground by -Cris Ellis) with flocked cardboard tube fitted with Japanese rack & pinion focuser.
Guide Scope ZWO 60280
Guide Cam ZWO 290mm
NEQ6 Pro stock mount on Heavy Duty 215mm diam/5mm gauge steel pillar
Canon 60D full spectrum modified
ASCOM, EQMod, Stellarium, PHD2, APT
I have always strived to see what I could manage using my setup for deep sky imaging and believe I have reached my potential with it. It is a very cumbersome rig and guiding has certainly allowed me to expand. Short subs of up to two minutes is possible but with such a long focal length it makes it a challenge to keep things neat and tidy.
I do enjoy each session however perhaps time to retire the scope for imaging and assign it for visual and planetary work...
The lure for a lighter short focal length frac and cooled cam is beckoning...
Cheers mate.
Regards,
Anthony
