L13: Gassendi & Mare Humorum

A rather quick sketch of Mare Humorum and a number of prominent craters, including Mersenius and Gassendi. The seeing for once was perfect, but after having finished several other sketches the same evening my endurance failed me.

Sketch made on 4 October 2014 using a SkyWatcher 10″ and a TeleVue Nagler zoom 3-6 mm.

Below is an earlier sketch focusing on the Gassendi crater. This was my first try at a close up sketch of one of the larger craters. At the time seeing was perfect, but light clouds kept interfering.

Sketch made on 10 February 2014 using a SkyWatcher 10″ and Baader Genuine Orthos 5 & 9 mm. North towards the bottom.
