Description

Alas the focus was a little off when I imaged this. I took another object just before this one, and it was fine then - I think it was the extra weight on the camera that caused this, because of including an additional battery and its holder - annoying! Anyway, it does not look too bad from a distance. I used my Nikon D800 again, which I am enjoying using, although the massive files take forever to stack, and each sub was 4 minutes long and at ISO 400. I also wanted to capture two globulars at once in the same field of view, hence my choice, but in hindsight I wish I had adjusted the field of view so the lower globular was higher up in the picture... but it was getting late, and tiredness was beginning to take over!
