It looks more like a difference in seeing or focusing.
Were these images taken on the same night or different nights?

In one night, but that's not the point, and focusing isn't the issue either—at the same object magnification, the difference is clear.
The smaller the pixel, the larger and more detailed the object appears.

That's clear, but I'm looking at the stars in the image from the 2600, and what's wrong with them? They look blurry and also larger than they should be—ideally, that shouldn't happen.

Everything is correct, the scale is the same in both photos, and on the small pixel of the 183 MC they look as they should, and of course, more detailed.
