Observing large open clusters

In the last few months I have been observing some large open clusters with binoculars. On Saturday november 20 last year I observed and sketched Melotte 20 in Perseus, also known als the Alpha Persei Moving Cluster. This huge starcluster has a diameter of almost 5 degrees. The observation was don with a 10x70 Fujinon binocular mounted on a mirror mount. The careful observation and the sketch took me about 1.5 hours. Later I scanned the pencil sketch into photoshop and made a more "realistic" version. Due to the mirror I use for observing, south is up and east is to the left.
