Description

Details

These filters allow for astrophotography close to a city and deliver optimal results. Optolong L-Pro nebula filters cause a significant contrast enhancement and therefore enable longer exposure times with DSLRs, color and mono astro cameras.

The exposure time can be multiplied by a factor of 3. This means, that you are able to expose three times as long than without a filter, before the sky background becomes visible. On the contrary, the light which the nebula emits passes unhindered. This results in a significant contrast enhancement and makes nebula photography possible, where it otherwise would not, even close to cities. Galaxy and cluster photography also greatly benefits from the L-Pro.
