Should I be using a light pollution filter when imaging galaxies? I image with a DSLR. From what I understand you want to collect the complete gamut of photons a galaxy makes and take more images, than you would at a dark site, to reduce the SNR. Does anyone have experience with this and any advice? Thanks for reading,

Just a follow up on my OP. I shot m81 and this time I took the CLS clip out. I think it is best to use the CLS clip for nebula and leave it out for here it is.
