Mars 2018-07-20 07:47 UTC

Description

Seeing remained excellent. After this photo, I took some time to view Mars through a Celestron Luminos 23mm eyepiece, which I affectionately call the "Beer Can Eyepiece". The difference in color between the South Polar Cap was surprisingly striking to the eye. Dark albedo markings were barely visible.

Notes:

Syrtis Major is rising.
The atmosphere above Mare Cimmerium appears to be less opaque than surrounding areas.
Hellas Basin has a few yellow clouds streaking over it.
The South Polar Cap still appears to be muted by the dust storm.
Most of the SPC also appears to be darkened.

Equipment
