This interesting discussion has induced in me a question about the impact aperture has on imaging.
Given the same sampling (in arcsec per pixel), would a large scope with large pixels capture more detail in comparison to a small scope with small pixels?
I know that it would make a difference for point sources of light (stars), but not sure about extended objects such as nebulae.
I also understand that small pixels mean shallower well depth so you need to have shorter exposures, but in case of Sony sensors read noise is also significantly lower than that of large chips and their sensitivity is relatively high, so apart from lesser FOV, perhaps not as much difference after all?
Any enlightening comments will be extremely valued and appreciated.
