The latest shots of Mezzoramia and environs are nice:

Another set of clouds from the May 28 observations. These are near Ganesa Macula around 50 N latitude:
I used a slightly different technique to bring out cloud detail. (I'm trying to find a systematic, non-manually intensive way to do this easily. Just using a high-pass filter has issues due to the gradient). Here is the before and after image: Here is an annotated image using Celestia. Cloud streaks indicated by solid red arrows, tentative cloud streaks with dotted red arrows. The orientation of some of the streaks is not lined up with the latitude lines, some appear slightly tilted WNW-ESE. The final combined image and the exact recipe I used for processing (all the nerdly details) can be found here:http://www.flickr.com/photos/31678681@N07/3581082151/ -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
