Coloured filter for looking at Mars


 Share

Recommended Posts

Personally I prefer the unfiltered view. Some people find a orange or light red filter helps accentuate the markings. A neutral "moon" filter might be helpful if you're getting glare; a green one will not be at all helpful on Mars, tending to hide whatever detail might be visible (apart from the polar ice cap).

I may not be an avid planet observer, but through the years i've learned a trick or three from some of the best, and filters is one of them. With my limited experience with Mars, certain color filters made the difference between seeing features or missing them. :icon_eek:

Blue and violet seemed to bring out the polar hoods and water vapor clouds.. without the filter, they weren't visible at all. Same thing with the way a green filter highlights fog on the surface. Red and orange positively identify dust storms because of the way they brighten them up.
