C11 Questions
I'm looking at picking up a used Cll XLT OTA to satisfy my planetary & deep space needs (especially imaging galaxies) and have a few questions:
1) Has anyone come up with an effective way of locking the primary mirror so as to avoid mirror flop? I've seen a few methods available but I'd like to know if anyone on these forums has sucessfully achieved this?
2) Field curvature & Coma - Which reducer / corrector should I be looking at? Would the standard Meade f/6.3 reducer do the job? Are there other ones out there better suited to the C11?
3) Piggybacking - I would probably look at piggybacking my FSQ106. Do you think the C11 OTA is solid enough for this?
4) Cooling - How important is this? I would like to get back into some planetary imaging. I've seen Paul Haese's Peltier cooling mod. Do I need to go this far? What advantages does peltier cooling have over installing fans alone?
Many thanks
Matt
