Hi,
What's CLS?
It's actually a Light Pollution Reduction/Suppression Filter. CLS is the Astronomik way of calling it... "City Light Suppression". :)

Have a nice day.

Nice acronym! Sounds like Clear Skies!
[80% Steve, 20% Alfred] ------- Probability of Clear Skies = (Age of newest equipment in days) / [(Number of observers) * (Total Aperture of all telescopes present in mm)]
