Andromeda Galaxy

M31 the Andromeda galaxy, can be found about 2.5 million light years distant. The galaxy contains 400 billion stars, though some estimates say up to a trillion stars. The galaxy is destined to crash into the milky way in the distant future. Does life exist, most likely it does.

This image, my best yet, is not an accurate representation of the true colour of the galaxy. But I can say the blue colour in the outer spiral arms are regions of young hot blue stars, whilst the orange central core area, is densely packed with much older yellow stars, these cannot be resolved, as they are to far away. The mass of foreground stars across the image all reside in our galaxy, the milky way. The smaller galaxies, at the bottom of the image M110 and M32 just left of centre are both gravitationally tied to the Andromeda Spiral.

61 images at iso 6400iso, at 25 seconds, stacked in deep sky stacker, with dark frames subtracted, 25 minutes in total. Canon 760D, 80mm F6 Refracter, on a driven mount, unguided.
