Description

Taken from my observatory (bortle sky 8) over three nights in March 2023.

Initially it was an LRGB only project, but I finally decided to do 100 180 sec shots with the Ha filter.

The main challenge was the integration of Ha since none of the different solutions adopted have given me satisfactory results. In total there are about 20 hours of exposures.

I would highlight the Galaxies that can be seen in the background of the image.

Although M51 deserves a cropped and close-up image, this time I have decided to give a panoramic image of that area of the sky so that the background galaxies can be appreciated.
