 First discovered in Dec 1764 by French astronomer Charles Messier, M3 is again a globular cluster with over 500,000 stars and an age of a mind blowing 11.4 Billion years old. Easily visible in binoculars or a telescope.

I was not going to give up on the chance of was last imaging run before we move and be without a working observatory over the summer months.

A few outside lights left on by my soon to be ex neighbour caused a few issues so I reduced the ISO to 400 and let off a few 5 minute exposures. This image was a total of 1 hour 20 minutes with a DDP stretch and star spikes. I am quite pleased with result despite the fact it is not the perect focus I have achieved before.
