Re: going for advanced RC6 setup #EXOS2 #astrophotography

Well heck.  Why not.  But do yourself a favor and use a guide scope.  Exos2 pmc8 will guide to about 1”, some get better.  It also works better in some areas of the sky.  Exposures of 3 minutes and longer have round stars at focal lengths of 900-1000.  Understand, seeing conditions usually limit your resolution and thus a long focal length is not going to get you much for DSO.  Lucky imaging for planetary will be nice.  At long focal lengths your astrocamera is going to oversample like crazy, and you will likely want to bin the images (DSO).

Can’t wait to see what you come up with.  I have an SCT with pretty good collimation.  It isn’t hard to do with out of focus star images, visually.  Maybe your algorithm will be an advantage.  

How much does that RC weigh?
