Hi Brent. I wanted a full frame sensor but not the cost nor time for a mono. So went ASI094MCpro. Which is the nikon d800 sensor jazzed up or cooled down , which ever you choose. It's a leap of faith but have heard good things about ZWO. No idea about this unity gain stuff though. Will eyeball it first. On an FSQ 106 should be sweet. My turn of the century sweetener!!
