I spent more time than I'd like to admit zooming into my DWARF 3 images and feeling like something was off. The targets were there. The images looked great at normal size. But zoom in and things looked softer than I expected.

What helped was understanding what the DWARF 3 is actually designed to do. It's a wide-field instrument. Short focal length, broad sky coverage, built for Andromeda, Orion, the Rosette, galaxy fields. That's its strength.

The tradeoff is that small details – a galaxy arm, a dust lane, a tiny background galaxy – may only land on a handful of pixels. When you zoom in, there may not be much more detail to reveal. That's not a flaw. That's physics.

I wrote a full breakdown of why DWARF 3 images look soft when zoomed in – link in the comments if useful."
