Thanks Greg. A lack of baffles could be partially responsible (this scope isn't baffled, although the tube interior is fully flocked), however I think the L-enhance filter combined with the fast f2.8 is mostly to blame. For comparison, this scope with the same camera and an Optolong UV-IR filter doesn't give halos, even on Alnitak
