I started imaging M33 with my 80mm refractor (FL=480mm) but later realized that it could fit into the FOV of my longer scope (FL=1333). The camera is the same in both cases, and it is a mono camera with LRGB subs in both cases.
Does it make any sense to combine both sets of subs? Perhaps just the color filters from the short refractor? I'd like to get some sense before processing the image.
