Astrophoto of M13 – The Great Hercules Cluster by Elodie

I’m sticking to “small” objects until the nebula season finally gets underway!

So here’s M13, aka the great Hercules cluster. I’d already shot it last year (or the year before that?) when I’d just bought my telescope, but the result wasn’t very good. This time I’m a little more satisfied, despite a problem with the flats that leave a haze on the image (I think I’ve identified the problem).

I can’t wait for the big nebulas <3
