Hi all,

Here are some more Mars images, this time from March 23rd. I was fortunate as seeing around sunset was excellent and allowed high resolution images. The images show the Elysium hemisphere following Syrtis Major.

Note Trivium Charontis is visible as a dusky marking, as well as albedo variations across Mare Sirenium/Cimmerium. Also the hesperia mouth is visible, which spans about 0.25" at the moment. The IR image probably is, i believe close to the limit of what the 12" is able to resolve.

Best Wishes

Damian

Hi all,

I attach a montage of the images i managed to obtain during the last several weeks. Images have S at top. Seeing was favourable on most evenings, The images reveal the familiar features such as a tiny SPC, Solis Lacus, and Mare Sirenium as well as other minor features.

Best Wishes

Damian
