I have been scared to shoot broadband from my inner melb backyard but with a few clear nights I thought I would through alot of integration time at the problem. My sensor has rotated between nights hence the gradients.
I also think I should have decreased the exposure time with the luminance filter. The S/N ratio was a bit high. Do others do that? Should my exposure with luminance be less than with my RGB filters?
