Optolong L-Ultimate Full Review | High Point Scientific

In this video, Teagan shares a full review of the Optolong L-Ultimate 2" Light Pollution Dual Band Filter, a fantastic filter for astrophotographers in heavily light polluted areas.

The L-Ultimate is a dual narrowband filter that only allows a 3nm bandwidth both at H-Alpha and OIII emission lines. This greatly reduces light pollution, allowing for a darker sky background with higher contrast. This filter has also been optimized to reduce haloing of bright stars.
