Description

Preparing future ideas I went through this asterism, close to a nice group of galaxies. It seems to be the smaller version of the Hercules keystone, but it is the Cetus keystone, even it is mention as such in Stellarium. The image is made of a two panel composition.
As revision B, the asterism is shown, and a full description of this, and a lot of other asterism, are in the book:  Pattern asterisms Book by John A. Chiravalle, (Patrick Moore's Practical Astronomy Series).
Also, there is no gradient in the image, it is the border of a nice area, with more clouds (or high density of stars) in the right hand side. I will integrate more time to give a deeper contrast to this. This limit between the two areas gives the sensation of a gradient.
