Title pretty much says it all. I have upgraded my ZWO stock filters (LRGB) to the 1.25" Gen 2 Astrodon filters. Now I'm starting to work on upgrading the SHO ones, beginning with the one used most: H-alpha. Looking for the mounted 1.25" Astrodon H-Alpha filter (Gen 2). Primarily interested in the 5nm version, though if a 3nm is available for a similar price, I certainly won't turn my nose up at it! Definitely want the Gen2 so I can keep everything parafocal between filters. :)

If you happen to have one you're looking to sell, just let me know! Thanks!
