Wow...very timely thread for me.
I was just going through my collection of astro gear and came across an older set of Meade Series 4000 1.25" color filters. I have never used them, don't know if they are quality or not, and really didn't have an idea of what their strengths and weaknesses are.
The set includes:
#12 yellow (74%)
#23A Light Red (25%)
#58 Green (24%)
#80A Blue (30%
Moon filter (13%)
I guess I have some filter testing to do.
