Hi Glend,
Considering your scope set up and the fact you mentioned the Atik 320E (which is now superseded by the 420), Have you heard about the new Atik 414EX which has a much more efficient chip than the venerable 314L+?
Thought I'd mention it
However the Pixel size is a bit more at 6.45 vs 4.4 for the 420
