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.

• The best visual and photographic filter for contrast enhancement for all telescopes, without loss of image brightness!
• The effect of the element neodymium as filter material is very impressive. When added to optical glass, it enhances contrast, enhances the red colour in the image (especially with Mars and Jupiter) and it darkens the spectral region which is particularly marked by street lamp light, which is the biggest contributor to the nightly "Skyglow".
• Planoptically polished and MC-coated – with IR-cut coatings!, without any loss of sharpness as a single filter in front of a binocular or be used for afocal projection with digital cameras (far from the focal point!)
• The IR spectral range is blocked making stars much sharper when used with dSLRs.
