Howdy
A little specific perhaps but chasing a 2" DGM optics NPB (Narrow Pass Band) Nebula filter that is either newish or in good condition without scratches etc!
OR a Lumicon UHC 2" would be great too!
Don't worry, bought a DGM NPD 1.25" second hand, a 2" version and a DGM OIII new in the US! All sorted and happy now! (well until I lust after something else....sigh!)
Kind regards
