Hi everyone. I’m currently doing my homework for an eventual purchase of a CCD imager to be used with my (C11) working in conjunction with a focal reducer of f6.3. I would also like to do wide-angle imaging with some old quality SLR lenses (28, 50 & 135mm) using SBIG’s specified adapter.
Can anyone please tell me what gives the best pixel match and image quality between SBIG’s ST2000XM and ST7XE when imaging through a C11? The ST2000XM has a KAI 2001chip with an imaging array of 1648x1214 at 7.4 microns. The ST7XE has a KAF- 0401E chip with an imaging array of 765x510 at 9 microns.
As mentioned earlier priority will be given to imaging at f 6.3 through the telescope. While I’m told “the ST2000 will give me more bang for my bucks,” I’m more interested in a correctly matched CCD imager for my telescope.

Thanks
