9/11/2018 · The L-pro and L-enhance have similar bandpasses, but the L-enhance is much more restrictive and just focusing around the emission lines of H-alpha, H-beta, and OIII. It wouldn’t be counter-produce, you would really (except for maybe changing the focus point a little bit) just be getting the same output that you would using just the L-enhance.
8/1/2016 · The Optolong L-Pro is a LP filter with stop band centered on frequencies common in street lighting. The Optolong L-eNhance is a multi-narrowband filter with narrow passbands at Ha, Oiii, and Hb emission frequencies. I captured 80 minute images of M20 (Trifid) with each filter and used the same PixInsight processes to create the images shown here.
6/18/2019 · There is more nebulosity in the L-eNhance data, especially in the OIII channel; There doesn’t appear to be much difference in the H? (red) channel; The L-Pro has a better overall background – the L-eNhance version has more gradients (I guess caused by the full moon), and some odd large red blotches toward the left of the image.
12/11/2019 · Optolong L-eNhance 1.25 “is an interesting filter that allows you to remove gas nebulae in conditions of strong exposure. By the degree of suppression of light pollution, it easily bypasses various budget filters against exposure – Svbony UHC, Svbony CLS, Baader UHC-S, Konus ALP, Optolong L-Pro. Comparison with analogues, In this video I take a look at the Optolong L-Pro light pollution suppression filter for city backyard astrophotography with your telescope and DSLR or cooled cmos camera. I also do a quick process in Pixinsight of the data taken with the L-Pro filter and show you the end result which is quite stunning considering the short amount of time I spent imaging M31 and it was taken in bortle 7/8 sky.

10/31/2018 · The L-Pro is a multi-bandpass filter that suppresses the transmission of select light pollution lines. For example, mercury vapor lamps, sodium vapor lights and even skyglow caused by the oxygen in our atmosphere. The balanced transmission aims to offer great color balance and minimal color cast. The Optolong L-Pro filter comes in 5 variations:, The Optolong L-Pro filter (2 inch version) is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lights including mercury vapor lamps, both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere …
7/10/2019 · The L-eNhance filter did a fantastic job of separating the glowing gases of NGC 7293 from a light-polluted sky. The Helix Nebula. ZWO ASI294MC Pro + Optolong L-eNhance Filter . L-eNhance vs . STC Optical Duo-Narrowband. Many readers have asked how the Optolong L-eNhance filter compares to the STC Optical Duo-Narrowband filter.
Here’s a cool comparison with a HyperStar C9.25 using no filter, a L-Pro Light Pollution Filter, and the new L-eNhance Filter from Optolong. The L-Pro has a 53% reduction of background light, and the L-eNhance has an amazing 91% reduction.
