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!

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 if you would like to get in touch.
