My wife's work has purchased 2 8" Dobs (XT8's) for outreach & they are in the process of getting full aperature white light filters for them so they can be used for solar outreach as well. They plan on a PST next fiscal year.
I came up with a screwball idea of using a 1 1/4" Ha filter in the focuser AND the white light filter at the same time. What would this get in terms of a spectrum shift/filtering? Would this be Ha scope on the cheap? I'm trying to get them to the point of a true Ha scope but with an 8" reflector it isn't intuitive or easy. My thinking is that the WL filter will reduce the total light energy enough that it won't instantaneously blind someone, and the Ha filter would do a bandpass to see the Ha.
