On Tuesday (the 21st April) of this week the clear weather continued and the four day old Moon hung attractively over the western horizon. Before carrying on with my deep sky adventures I thought I would use the Dwarf 3 to photograph it. This is what I obtained at 21:47 BST:-
The Dwarf takes 20 frames (in this case with a shutter speed of 1/160s and gain 10) and then stacks them to obtain a better resolution image. I have cropped the original. This is the raw, unprocessed image - I felt that the one obtained in Stellar Studio looked a bit over sharpened. This is actually how the Moon appears to the naked eye with North up and West to the right. Below, I have annotated one or two features of interest:-
January before last I tried drawing the crater Atlas as I saw it though my 4 inch refractor. Vallis Rheita looks like a tectonic valley but is actually formed from an overlapping chain of impact craters.
