Rilles Between the Clouds.

Postby Aratus » Thu Mar 17, 2016 12:38 am

This evening (16th March) the skies sort of cleared for about at hour just as the sun was setting, before clouding over again. Only enough time to view a 60% moon, and rattle off some shots.
The rilles in the Sinus Medii looked particularly good. In this shot you can see the Hyginus Rille, and its little crater half way along its length. The fainter set of Triesnecker rilles can seen in the lower half along with Triesnecker Crater. Agrippa and Godin are the craters to the lower right.

The best time to see these rilles is just after half moon. In a day or so, they won't be nearly so obvious.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.
