The 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.

EOS Clip version of the famous L-eNhance filter by Optolong

Optolong L-eNhance is a dual-band pass filter which has been designed for DSLR (digital SLR), color CMOS and monochrome CCD cameras. The convenience and cost effectiveness of this filter allows amateurs to image a rich selection of astronomical images, even in bright, heavily light-polluted areas. It effectively isolates the H-Alpha, H-Beta, and Oxygen III nebula emission lines and achieves a maximum transmission of up to 90%. The performance of this filter delivers superb images.

L-eNhance 2" Optolong filter (M28x0.75) 50.8mm - Recommended for: shooting in double pass band (H-Alpha, OIII and H-Beta) with CMOS or CCD color cameras or DSLR

L-eNhance 1.25 "Optolong filter (M28x0.75) 31.8mm - Recommended for: shooting in double pass band (H-Alpha, OIII and H-Beta) with CMOS or CCD color cameras or DSLR
