Astronomik CLS filter 2” with case - sale pending
Astronomik CLS filter 1¼” with case
Must be sold, will take any sensible offer.
(The new prices are $249 and $125.)
Both in excellent condition.
Astronomik says:
"The Astronomik CLS blocks the light of the spectral lines of mercury and sodium-vapor lamps and lets the largest part of the visible light and H-alpha emissions pass. All the important emission lines, as well as the spectral region that the very well dark adapted eye can see, can pass through the filter."
(Note that these are designed for visual observation – they do not have infrared blocking for astrophotography.)
Moon filters 2” with case (Bintel) $20 - sold
