Not suitable for use with calcium quark
I got this because I was tired of moving my Svbony 2" UV/IR cut between my Calcium and H-alpha filters. However I immediately noticed a 10x increase in exposure times--the Baader cuts off just enough of the blue frequencies to interfere with the calcium quark. I will probably keep it because I do intend to do some planetary later this year.
