The Andromeda galaxy,
known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years) from Earth, and the nearest major galaxy to the Milky Way. Its name stems from the area of the sky in which it appears, the constellation of Andromeda.

Like the Milky Way, the Andromeda Galaxy has satellite galaxies, consisting of 14 known dwarf galaxies. The best known and most readily observed satellite galaxies are M32and M110. Based on current evidence, it appears that M32 underwent a close encounter with the Andromeda Galaxy in the past. M32 may once have been a larger galaxy that had its stellar disk removed by M31, and underwent a sharp increase of star formationin the core region, which lasted until the relatively recent past.

M110 also appears to be interacting with the Andromeda Galaxy, and astronomers have found in the halo of the latter a stream of metal-rich stars that appear to have been stripped from these satellite galaxies.M110 does contain a dusty lane, which may indicate recent or ongoing star formation.(Wikipedia)

Excellent work Marios! Thanks for sharing your nice M31!

This is beautifully done Mariosi. The proportion and placement of M32 and M110 are very precise. The extension of the gauzy arms of Andromeda are also as looking through the tekescope.
Do you use any kind of grid work on your sketch work to help with placement and orientation? This is the difficulty I have when I attempt to sketch a starfield. I seem always to get things skewed.

Thank you for the nice comment. I don't use any kind of grid work on my sketches or geometrical instruments ... count with the eye.
for me the best teacher is night sky, just wants patience.

Woah. I was confused when I saw the comments above referring to your "sketch." My first reaction was "but that's not a sketch, it's a photograph." Then I took a closer look. And then another look, and at your description of it, and then I realized that it really is a sketch! Impressive work indeed!

Marios, that is really nice! I'm like AntennaGuy; I thought it was a photo as well, then I read the bit about your eyepiece :D

The horse sketch is just great as well!

All the best and thanks,

Now that is a really cool sketch Marios which reflects exactly what one sees at the eyepiece. You have captured the subtle gradations of surface brightness between M32 and M110 very successfully, plus the dust lanes are rendered beautifully. I too was fooled into thinking it was a photograph!
