So, the ASI034MC has a pixel size of 5.6um. So 5.6/0.275 = 20. So a 2x barlow would make my f/10 scope f/20, right?
And the ASI120MC has 3.75µm pixels, so that would be f/14, which is like a 1.5x barlow. Does that make sense?
And given the right barlow and the right focal resolution, would both cameras essentially give equal quality output?
