Hi Sam. I've taken a different path, and after seriously considering the 8300 chip, decided to go with the 4022M in a SXVR-H16,in part because I already own a 1.25'' filterwheel and colour and narrowband filters, and also the better well depth and read noise of this chip compared to the 8300, this will allow me extra exposure time before anti-blooming cuts in and reduces sensitivity (good for the faint stuff) I figure. At 7.4um pix size, my general seeing, and the scopes f7.5, the numbers crunch o.k for me, so I'm envious in a way of the large field, but then again,size is'nt everything
Also, between Claude in Aust, and Terry at Starlight Xpress in the U.K I know I'm well looked after in terms of aftersales service and costomer support
Looking forward to seeing the results of whatever you decide upon!
