Hi All,
Selling my 1.25" filters as the don't see starlight any more since I acquired a 2" filter slider and a set of 2" filters. I kept these filters in the Orion Filter wheel protected from the dust and elements. Optical surfaces are clean.
Celestron LPR (Light Pollution Reduction) filter in the original box (I am the first owner):
$50 + delivery.
This LPR filter worked quite well with my 12" dob from a moderately light-polluted environment. It is not a narrowband filter like straight UHC is but is supposed to block sodium-vapour emissions (majority of street lights) as well as natural sky glow. It does not dim the stars like normal UHC filter.

The other two filters are now sold.
