@apalu @thomasfuchs yeah, that'd be the reasonable thing but I'm just looking at sdss images which aren't necessarily timed for the individual sources on their plates, so sometimes they get really nasty when there's a bright source.
This is a project mostly just to make a pretty picture for my wall so I assume I'll be able to get by by reducing the aperture from what sdss uses (2.5m i think?) down to whatever I can afford and tinkering with exposure times.
Idk honestly this is maybe just me looking for an excuse to dabble in astrophotography
