I was surprised by the lack of light rays and I put it down to the excellent baffling as well as excellent anti reflection coatings and extremely black absorbing paint. No doubt the fluorite element has an impact on that as well with less scatter.

Yuri uses this extremely black super absorbing paint to paint the interior of the tube. He researched what was the blackest most absorbing paint around. It is blacker than both my Tak scopes and the AP.
He posted images of it compared to other black paints and it is really black.

Greg.
Sounds pretty good.

When you use the bigger chip it might be a different story though..? Hope not. While not usually a big issue in the scheme of things, off field flares are a pain really. I never had them with my small SXV-H9 chip (9mm X 6.7mm) and the Starfire but the bigger chip seems to pick'em up much more often. Might be the inner surfaces of the extension pieces I use though..?
