For some time now I've been using a polarizing filter on my quark. This variable polarizing filter was purchased back around '02 from Orion for lunar and when rotate rightly enhances solar h-alpha surface detail (weakening prominences.)
The problem with this filter is that it doesn't screw into my eyepiece barrels very well. I was wondering if anyone has any recommendations for polarizing filters for visual use. I note that virtually all my other two inch eyepieces have accommodate my variety of two inch filters OK. I think the issue here is the 2002 Orion threads.
I see there is a fancier Alpine-Astro Baader version of the variable polarizing filter. But I was thinking maybe there is a one filter polarizing option that is not to bright and not to faint. It seems to me that I use the one I have in one position, implying that a non-variable polarizing filter might do the trick, if I knew which one to get.
