Hi

I am trying to reduce light pollution in my images (live very close to city) and I was thinking of getting something like Baader UHC-S for my ED80 + DSLR (Nikon D90 ATM). I am also thinking of getting a reducer/field flattener at some later stage.

I am confused about sizes and how things get mounted:
1. The pollution filter comes in 1.25" and 2" which obviously is supposed to match the eyepiece (does it screw into eyepiece?). What size do I need for imaging with a DSLR? How does it get mounted?

2. What about the reducer/field flattener? For example Skywatcher ED80 0.8x. How does this get mounted? It seems to be 2" - do I need 2" light pollution filter to match it? Does the light pollution filter gets mounted on it?


Also what would be the recommended reducer/field flattener for ED80 (Skywatcher)? There are lots of reviews on the Internet but most seem to be several years old and the mostly recommend William Optics 0.8X II FR has been discontinued.

Thanks in advance
