Non-reflective black coatings for inside of scope tubes
Is there much noticeable gain with Newtonians from using flocking paper or similar compared to flat black spraypainting the inside of the tube?
If there are materials significantly better than flat black paint, where can they be purchased and what do they cost?
Or, does anyone who has gone down this route wish to opine that it makes little difference in practice and is not worth the cost and bother for a typical backyard dob with mirrors that will soon be a bit grimy anyway...
