Melotte 111: the Coma Berenice Star Cluster

A few weeks ago I observed the Melotte 111 in Coma Berenice. This huge star cluster with a diameter of at least 5 degrees is actually too big for most of my instruments. I used the skywindow and my 8x42 binoculars with an 8 degree field of view for the sketch. It is a truly great object for binoculars.

South is up, East is to the left.



Updated sketch of Stephenson 1

At the moment I am trying out new methods for digital processing of my sketches. The sketch below, of Stephenson 1, an open cluster in Lyra, is based on an observation I did a few years ago. I do all my sketches in pencil and on white paper, scan them into Photoshop, and proces them. The method I use is based on several different manuals from fellow astronomers who sketch at the eyepiece, but mostly on Peter Vercauteren's manual (http://www.astronomydrawings.com for Peter's website) and Jeremy Perez's manual ( http://www.perezmedia.net/beltofvenus/ ). The beautiful sketches of these guys are an inspiration for me!
