I underestimated the difficulties related to M81 imaging during the picture. The alignement was not perfect and even the focus was not optimum. I also underexposed the object so that the outer rings of the galaxy are not very visible in the picture.
I will be better next time.
M81 is a majestic spiral galaxy at about 10 million light years from our galaxy. It is a low density, and thus low superficial brilliance, object. It forms a beatiful pair with M82, irregular and very active galaxy.
