Hello, I just bought a skywatcher 100ed and the .85 reducer. Can I use 2in filters behind the reducer and in front of the t mount? Will that effect the focus? Is it the same thread type? I am totally new so any help would be appreciated.
Thanks!

Not sure with the .85 but with my Orion 0x8 FR I can unscrew the barrel and put my 2" Orion sky glow filter on then reattach the barrel.

 I believe the 0x85 screws onto the SW drawtube.

Putting the filter on camera side may not give you the 55mm back focus if using a DSLR

 

Or you may need something like this.
