"Poor man's filter"
I really think some of you may have missed the point. The title said it all - a "poor" man's H alpha filter. Sure I've read all about the 7nm and 13nm narrow band H alpha filters but for a 1 1/2" its $200 and 2" $400+ for such a narrow band filter. Big bickies for some of us. If you took the time to look at the transmission characteristics of an MV1 from Sirius Optics and a red filter you would wind up with a 50nm H alpha filter which in light polluted skies of BrisVegas is better than nothing. Since most of us have both these filters, I thought it would be feasible and since Baader say in their literature (see above quote) its very good - then I thought it was worth mentioning. Ill give it a go with my ST7 for all the doubters and nitpickers.
