Unguided Imaging with a SCT


Bruce Donzanti
 

I am guiding with an OAG on a C11" EdgeHD @ f/10 with a ZWO ASI6200mm Pro but finding guide stars all night long can sometimes be a challenge.  My primary mirror is locked down and focus is performed with the Optec Secondary Mirror FastFocus System.  So, mirror flop and shifting are non-issues.   Thus, I am curious if folks have successfully modeled and performed unguided imaging on a SCT.
