Baader TZ3I had been imaging the sun for a long time now but nobody made a telecentric 3x until now. My telescope is a F8 refractor and a 2x would only give me a F16 system while the available 4x would give me a F32 all but useless on most days where the seeing conditions are not perfect. Glad to see that Baader has answered the calls for a good telecentric lens of 3x.Randy
