meanwhile... 23 million light-years away...

edit:
v3: better color tones and processing (deconvolution)
v2: reprocessed from raw, better details and colors :) hurray!

M51 and the first light of my new camera :) Despite the purchase, not recommended by many for this type of shooting (long focal length), I did not put off, I was and am convinced it was the right choice (my wallet less)

specs:
Celestron C11 XLT mirror lock mod + Starizona 0.75x reducer on a Skywatcher EQ6 - ZWO ASI1600mm-cool camera and Lacerta standalone guide
45 shots for luminance (bin 1x1, 138/30 gain-offset, 150 sec for shot)
10xRGB shots (90 secs for each)
In the comments the photo of the full setup and location (Monte Beigua, Sassello (SV), Italy)

I am aware that it is not perfect, but after three months of abstinence, with the new camera and bad weather ... a couple of days to corse with convoluted software for masochists that I hate .. and I refuse to pay .. This is the first image, a little bit cropped and not very well framed, but
we are proud of! :)

The Whirlpool Galaxy, also known as Messier 51a, M51a, or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus in the constellation Canes Venatici. It was the first galaxy to be classified as a spiral galaxy. Recently it was estimated to be 23 ± 4 million light-years from the Milky Way, but different methods yield distances between 15 and 35 million light-years. Messier 51 is one of the best known galaxies in the sky. The galaxy and its companion, NGC 5195, are easily observed by amateur astronomers, and the two galaxies may even be seen with binoculars. The Whirlpool Galaxy is also a popular target for professional astronomers, who study it to further understand galaxy structure (particularly structure associated with the spiral arms) and galaxy interactions.
