Cloud sadly stopped another dark sky session, and last night was the first chance to get a scope out in a month, though it was from home - you take what you get I guess. High cloud rolled in by the time the 45 minute sketch was done.
The Wishing Well cluster is a naked eye DSO, just east of the Eta Carina nebula. It is often mistaken for Eta Carina through a finder. It is a big sucker, nearly 60' in size, nearly twice that of the Moon.
This immensly rich and bright cluster is best viewed through binoculars or a rich-field-telescope.
In this sketch too, I included a AFOV white ring to give a sense of the size of this cluster. With the eyepiece I used, the AFOV is 2.5deg!
This cluster also presented a common problem associated with sketching open clusters. They usually end up looking flat and lifeless - just a bunch of white dots on a page, and nothing like the bag of diamonds you see in the eyepiece. This first image shows the original picture - flat, and unimpressive, .
