Needless to describe a so well known object, despite the observation has been made with a large scope: 25” dobson Obsession.

The interesting features are, according to me,
- the upper halo which points out easely,
- and the very small twin galaxies at the lower left, seen only in adverted vision, hardly, and not separated. It is not suprising: they are at about 18th magnitude! Both have been imaged by the HST, and can be detailed in several APOD photos.

My picture, as usual, is drawn on a Canson paper, sheet of 200 gr/cm2 and 21 x 29.7 cm, with graphite, stump-drawing, and ink of China.
Then scanned, turned in negative, and finally legend, scale and compass added.
