When I first examined this I really questioned whether I wanted to sketch this open cluster. I decided to try and tackle it and just sketch what I could see. I had done M25 and several other sketches of other open clusters lately since I think they are often ignored this time of the year. I've been recording my observations on a digital recorder and uploading them to iTunes and am going to add a new dimension to my blog/coming Web Page. I am going to post up my audio observations of the items I am sketching. For me I find by keeping a written record and an audio one it helps me to remember what I am seeing as I am seeing it and I can return to listen to the observation again while I re-create it digitally. The cluster is 2150 ly away from us and is estimated at 27 arc seconds across or 15 to 20 ly across. It is a rich cluster and between 129 to 147 members have been counted depending on which observation you go by. Finally it is estimated at 220 million to 300 million years old.
