Hi
From my backyard in the city I've always used an IDAS pollution suppression filter with my 450D DSLR. I'm still planning to use my MPCC on the front of the QHY9+FW when I get it all, and I imagine while shooting from the city I should still put the IDAS LPS on the front of the MPCC?
Any thoughts appreciated.
My thinking is just because I'll be shooting separate LRBG shots, there's nothing that's going to help with light pollution?
