That'a lovely, well-balanced and natural-looking image, Martina. Perfect compositional balance between the object and the sounding sky space. Nice round stars too!
Cheers
Martin
Thanks Martin, I’m enjoying my new hobby/new job. Still lots to learn which is fun and will keep me out of trouble J
Clear skies
A fair few of the globular clusters show up too. Look for the relatively faint orangey "stars" around the edges of the galaxy.
Impressive how much you know about M81. I just had a look at your images of it, well done for your study on it. It's amazing what lies out/up there and what knowledge we humans are accumulating on it all as the years go by.
Hi Martina,
Can't find out how to send you a direct message through the BAA website.
I also live near Cambridge (right now and about half the year). Please drop me a line at paul@leyland.vispa.com if you would like to get in touch.
Cheers,
Paul
