Now with some experience with 2 different cameras on the same telescope, I can see how these different setups have different field of view and it can affect the framing of images. The cameras in this comparison are Nikon Z6, a full frame DSLR with 6048x2024 pixels and ZWO ASI533MC-PRO, a dedicated astrophotography camera with a cropped sensor with a resolution of 3008x3008 pixels. The same target was imaged using same telescope, William Optics ZenithStar 61, attached to these cameras and the difference in field of view is huge as seen here. They are processed differently at different times, hence the overall image quality should not be compared here, just the field of view.
