OPTOLONG L-PRO FILTER finder The optional SkyWatcher coma corrector

The optional SkyWatcher coma corrector for f/5 Newtonian corrects the coma superbly

the rim around the generator reduces the white light disturbance (a must have in star parties where white lights are prohibited)

About 90% at 672 nm

up to 100 alignment stars for modeling

His idea was to mount a Newtonian telescope on an easy-to-use alt-azimuth mount that does not need time-consuming electronic alignment

OPTOLONG L-PRO FILTER finder The optional SkyWatcher coma correctorThe Optolong L Pro filter is a light pollution multiband filter designed to reduce the effect of light pollution while offering a great white balance. CLS, UHC, L eNhance, L eXtreme and narrowband filters are very effective in increasing the contrast of emission nebulae but they are ineffective on deep sky objects that have a continuous spectrum such as galaxies, globular clusters and reflection nebulas. The L Pro works as a universal light pollution
