ASTRONOMIK
CLS Light Pollution Filter
Fits Canon EOS Series DSLR
Description:
I've upgraded from a Canon 60Da DSLR to a dedicated cooled
astronomy camera for my observatory, so I'm selling the filter.
This
filter has been a life-saver for the light polluted skies of the Seattle
area (couldn't help with the famous clouds though!). Filter really
worked well for longer exposures and pulling out the small details from
the light dome of the big city which was about 15 miles from my backyard
observatory.
I've recently moved to darker skies, so I'll have to
see how the new camera works out, but these only fit into a Canon EOS
family of DSLR cameras, so I'll be replacing it with a 2 inch filter if
needed.
The filter was used on my camera probably 95% of the time, only removed when trying planetary or lunar images.
