One of the first images taken with this telescope and camera. Extremely unlucky.

Hello, do you shoot stars through a UV/IR cut filter?

Are you referring to the UV/IR + SV240 combination? Yes, together, UV/IR is necessary for the refractor, otherwise stars bloat, and I got the SV240 to cut out urban light pollution. The filter handles it well, but colors need to be balanced.
