I know I have some tilt in my image train at the moment, runs on a diagonal from top right to bottom left.
Someone with a bit more knowledge may be able to tell me whether tilt can be diagnosed from flat frames?
Ideally, I'd likely to be able to reduce it at home without having to waste dark clear skies
Pretty much assume I'll need star tests but hoping flats and CCDInspector may fix the situation.
Has it been done before? Couldn't find anything in a Google search.
