Cheap Mars filter.

[Peter Drew]

I discovered this last year.  I accidentally breathed on to my eyepiece which produced a light misting.  Instead of waiting for it to clear I continued to look at Mars.  As the mist cleared it reached a point where the filtering was just enough to reduce the glare but at the same time revealed the best detail.  I tried this again recently, on purpose, and it still works!        🙂
