Andromeda
The Andromeda Galaxy (M31)is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest major galaxy to the Milky Way. The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda.
The mass of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion solar masses and it has a diameter of about 220,000 light years.
The number of stars contained in the Andromeda Galaxy is estimated at one trillion, or roughly twice the number estimated for the Milky Way.
The Milky Way and Andromeda galaxies are expected to collide in around 4.5 billion years, merging to form a giant elliptical galaxy or a large lenticular galaxy.
Also visible in this shot are two satellite dwarf galaxies, M32 and M110 (the two other fuzzy star formations to the left and just below Andromeda).
ASI 2600MC Pro cooled to 0degC. William Optics GT 81, Flat 6AIII, ASIAir Pro, HEQ5 Pro guided, 15 x 90s lights, 45 180s lights, 40 flats, 80 bias at gain 100. Bortle 2 skies.
Stacked in DSS and processed in PS and LR.
Pretty pleased with this. First light with the ASI 2600MC Pro, second time out for the GT81 and my first attempt at Andromeda since I took up astro about 6 months ago. Got some elliptical stars in the corners but I'll work on that with the flattener adjustment.
