Venus 11 April
Coastal seeing and tons of salt in the air meant the Cass stayed inside, again. And again, the ol' dob delivered. As usual, image scale wasn't the best, but there was still a bit of cloud detail to be captured. Instead of trying a false-colour composite (I'll leave that for days with better seeing), I thought let's see what can be pulled through the #47 "Violett" filter I got from TS some time ago. There are some things one can make out, with some squinting. Not bad, considering the #47 is a fraction of the cost of the UV filter. Using the 47 visually, I thought the limb of the planet appeared darker near the equator than the poles, and the drop in brightness towards the terminator was greater than without filter.
