Optolong L-Pro Filter 1.25" Nebular Filter for Astrophotography

Optolong L-Pro Filter 1.25" Nebular Filter for Astrophotography

The L-Pro Astrophotography filter is a filter for improving the contrast of deep-sky objects and dampening the sky background.

  • blocks UV and IR (700 - 1100 nm)
  • high transmission at passband
  • improved color balance for DSLRs and One-Shot Color Astro Cameras, e.g. ASI Color Cameras cooled or uncooled by ZWO.
  • high optical quality
  • in 1.25" filter cell
  • The L-Pro Nebula filter permits roughly 3x longer exposure times than without a filter and therefore improves contrast significantly.

Product description

Optolong L-Pro Filter 1.25"

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.
