Hi All,
Selling my last remaining 1.25" filter - Celestron LPR (Light Pollution Reduction) filter in the original box (I am the first owner). I kept it in the Orion Filter wheel protected from the dust and elements. Optical surfaces are clean.
[SOLD] $50 delivered in Australia (less than half the original price!)
This LPR filter worked quite well with my 12" dob from a 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.

Thanks,
