An anti-pollution filter
The L-PRO Optolong filter is suitable for reducing light pollution due to artificial light and at the same time it is suitable for highlighting emission nebulae.
It is a broad-spectrum filter, it passes almost all wavelengths at 100% and cuts only the harmful ones; thanks to this, it can also be used on small telescopes.
Unlike narrower band filters, it does not alter colors; it is particularly suitable if used near cities, suburbs, villages or in the countryside.
Recommended for: reducing light pollution, increasing the contrast of emission nebulae
Recommended use for: DSLR, CCD or CMOS color or monochrome cameras
