Hi!
I have an 8-inch catadioptric, an AM5 mount, an off-axis guider, a Canon 60Da and an Atik 383L+ mono cooled camera. It should be good hardware for deep space photography. However, now I live in a Bortle 8 region.
I have two old filters: a Lumicon Deep Sky 1.25", and an Optolong UHC clip for the Canon. I was told they're not ideal anymore, since we're gradually switching to LED light instead of sodium and mercury light. And I see they're not helping much.
Right now, what is the best type and brands of filters for imaging galaxies (I guess it should be trickier than emission nebulas)?
Thanks in advance.
