Re: Close up of M81 without CCDT67
Perhaps... probably would be fine. The 2.5-5um pixel size range of the common CMOS sensors these days will demand good seeing at that kind of focal length, but it's workable. What I would do is always image at 1x1and bin in post-processing (PixInsight's IntegerResample process, for example) on an as-needed basis if the pixel scale needs to be worked up a little due to the conditions.toggle quoted messageShow quoted text
1600 would be great for detail studies of all kinds of nebula, too.
For reference, Robert's camera sports 4.63um pixels. I have the same one, but QHY's version of it, and its Sony IMX294 is a really nice and super clean 4/3 format, 14 bit sensor with dual gain modes.
