PeterBolt Posted October 7, 2021 Share Posted October 7, 2021 I've just fitted this mask to my primary mirror...I am hoping it will improve my star shape.

paul Posted October 7, 2021 Share Posted October 7, 2021 I'm interested to see how it works out. My Bresser is pretty good now I shortened the focuser, reducing some of the asymteric flares would be a nice tweak. 1 Quote Link to comment Share on other sites More sharing options...

It works by blocking the very edge of the primary mirror from the turned down edge that causes light to scatter causing flaring on brighter stars 1 Quote Link to comment Share on other sites More sharing options...
