Re: dieter martini solar scope
Hah! I have tested four (!) such LS50F filters in a telecentric mode and none(!) of them work well.
I tested them in F/20, F/25, F/30, F/40 and F/50 modes. Just a waste of time. These 50mm filters are not as good as Coronado PST etalons. They are way too wide and way too low contrasty.
I even make them double stacked - a tad better and MUCH worser than a simple OK quality Quark Chromosphere.
