Description

Quick 30 min test of ny newish Sigma 28mm DG HSM at f/1.4
I'm hoping to shoot a few constellations with this wide angle lens - ideally with lots of nebulosity, but Ursa Major was the only one available in the tight cloudless window I had.

But the test was a success, it came out ok and I love that, if you zoom in, you can see all the big favourites M81, M82, M106, M97, M108, M51, M101 off the top of my head.

I used Bill Blanshan's star reduction script but (with the small stars protected) used the transfer method at 0.7 so it actually increased the size of the main stars to make them stand out a bit more.  Pleased how that worked out
