TareqPhoto Posted June 15, 2021 Share Posted June 15, 2021 Hi all, Is a doublet scope good for astrophotography? And i am only thinking about Ha filter or narrowbanding filters in general and only Lum filter, not RGB filters, and maybe no OSC camera, but let's say we add OSC camera then we use that L/LP filter to kill/reduce halo, but in general, is it great enough to have sharp contrasty images same or similar to a triplet? We know a triplet is better, but it is always about how the triplet treat the light path for the colors or RGB, but is that also applicable with NB filters or Lum filter?
