I generally use my DSI Pro 2 for imaging instead of my Canon 40d as I don't have a Light Pollution Filter as such and the DSI's work well at suppressing it. While rummaging through some of my gear today, I came across my old Meade Series 4000 Nebular Broadband filter which I dropped ages ago and now has a chip in the edge of it. This is not visible during visual observations and could be cropped out of an image if needed. I did a read up on the filter, and holding it up to the light, it does seem to do what the other LP filters do to the colour spectrum as in the colour comparison chart I have seen from a link through this site. It also enhances Hb, OIII and Ha while suppressing sodium, aural glow, reflected light, etc. Could I use this in replacement of and IDAS LPR Filter and see what results I get, or would this not work at all?
Thanks.
