Optolong L-Pro Filter 1.25"
US$ 145.68The L-Pro Astrophotography CCD 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.
