Technically not as big and bright as LMC and SMC that we can see easily here in the Southern Hemisphere, Andromeda is a massive spiral galaxy seen from the Northern Hemisphere. So it was with some surprise that after taking some test images I realised I was close enough to the equator to actually have a decent go myself! It didn’t get higher than 21 degrees. If you’re not sure what that means.. hold your arm out flat. That’s 0 degrees. Now point straight up in the air. That’s 90 degrees. 20 degrees is a slight tilt upwards from your arm being flat in front of you.

To give you an idea of scale, you could fit 4 full-moons in this image from side to side. In the middle, like most galaxies, is a black hole holding the whole structure together. You can also see a smaller satellite galaxy underneath the main disc, which is M32.
