While "working" today thoughts always turn to all things astronomy. I was thinking about, image scale of about 0.25 arc seconds/pixel for my white light imaging with the Evostar 120mm. Using my DMK21 I have to push the focal length up to 4500mm to achieve 0.25". With the ASI120mm its only 3000mm for 0.24". I am guessing I should be using the ASI120 at least for white imaging? Surely imaging at a much shorter FL but retaining the same resolution is going to be more forgiving to the conditions. I do use the DMK21 for H/A, but that is due to the lack newton rings problem associated with the ASI.
