Optolong L-Pro Filter 2"
US$ 169.30The L-Pro CCD filter improves the contrast of deep-sky objects and reduces 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 2" filter cell
- The L-Pro Nebula filter permits roughly 3x longer exposure times than without a filter and therefore improves contrast significantly.

Optolong OIII Filter 6,5nm 2" (50.8mm)
US$ 200.49Extra Narrowband OIII-CCD 6.5nm filter is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, and both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow).
