[skysurfer]

I looked up Jupiter well before sunset with my 11cm ED without problems, but when I put a pol filter (way too large to screw it in as it is 52mm) behind the eyepiece and rotate it properly, the blue sky background is MUCH darker, while Jupiter does not get darker. This enhances contrast considerably, so awesome ! I could also find the nearby Alpha Librae, but not the moons.

This works best for objects 90 degrees from the Sun like Jupiter now.
So now I ordered a 1.25" pol filter to screw in my eyepieces or diagonal.

Any other experiences ?
