Chuck Hards was kind enough to offer to make a custom fitted white-light solar filter for SPOC's Bogdan refractor so I brought that up at last evening's SLAS board meeting. There was some discussion about whether any such filter should be make of mylar or glass (to be determined) but one thing that I'd like discussed here is the size of the filter itself. Usually when it comes to telescopes I think "bigger is better" but in this case I'm wondering if it would be better to go full aperture (200mm) or would we really gain that much by going full aperture over something smaller. Opinions? patrick
