Meade #908 broadband Nebular (Light Pollution) filter.
Screws onto standard filter threads on 1.25" eyepieces.
My primary interest is lunar and planetary, so this filter
has been sitting in it's box since I purchased it back in
1984. Multi- layer coatings have never been touched, and
the filter is in new condition. Today Meade is asking $80
for this filter. Will let it go for $30 shipped. (CONUS)
