An attempt at capturing the clouds on Venus & Mars
by Eagleseye on , under Astronomy
Using my monochrome webcam I tried to capture some of the cloud detail on Venus.
I used a purple filter and a UV/IR cut-off filter. I tried various exposures and settings, but no joy.
Oh well, at least I got a reasonable image of Venus showing a thick crescent phase.
I also had a go at Mars in colour as well while I was at it.
Maybe it’s now time to upgrade from the humble webcam?

Hey, instead of using the UV/IR cut, use a blue filter along with a *47 Violet filter. . Venus clouds will appear if you let the UV in. If you cut the UV off, the clouds won’t show. The monochrome webcam should be fine for this purpose
I hope this helps.

Thanks for the tip. I will give it a shot. Any particular blue filter, or would a blue filter from an RGB set do?
