All going well, I will be getting a hioptic ED80 480mm with some extra gear to juice it up for some nice imaging.

I intend to attach a Light Pollution Suppression filter as I live very close to a massive shopping complex which unfortunately lights up the sky..

I decided that the Hutech LPS was the way to go until I read... :

"LPS filters are available for 1-1/4" and 2" (48mm) eyepieces, as well as in numerous sizes to accomodate most popular camera lenses" Link (http://www.sciencecenter.net/hutech/idas/lps.htm)

So I guess my question is, where does this thing attach to? I care less about my eyes than the camera, so I want it to attach to the camera of course, not the eyepiece. So does it go... camera --> LPS --> Scope?

I'm just a little confused.. :shrug:

If you have a Canon camera you can get ones that clip in. Alternatively, the camera T-ring adapter will be threaded for 48mm filters. Extension tubes and field flatteners also have 48mm threads for filters.

Thanks, I have a Sony Alpha and was intending to use this connector. (http://www.ebay.com.au/itm/Telescope-Camera-Adapter-Sony-Alpha-2-Ultrawide-/260502722870#ht_1038wt_932)

Yep, that should have a 48mm thread for filters.
