Doots Posted October 20, 2021 Share Posted October 20, 2021 Hi backyarders! Just a quick one I use a bahtinov mask for focusing but I was wondering… Has anyone here tried a tri bahtinov mask on their sct for focus and collimation? Thanks in advance for any replies Bryan Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted October 21, 2021 Share Posted October 21, 2021 It looks an interesting concept Bryan. I don't have an SCT so can't really comment. 1 Quote Link to comment Share on other sites More sharing options...
