    2" CLS Nebula Filter is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Good Quality Nebula Filter The CLS is a high quality Nebula filter for its marketed niche. It provides higher % light transmission than many other competing brands. While not offering as strong of filtration as an UHC or O-III filter, the CLS also does not dim the image as much so is quite useful on my 80mm refractor.
