Description

Recently I was able to spend some time at Hakos, the legendary Astrofarm in Namibia. The nights were so clear as one just can dream, and the summer milky way overhead looked like a giant edge on galaxy spanning the whole sky - just what it is actually, but we can rarely see it that impressive.

The Antares region is one of everybodys eternal favorites. As I can hardly reach it from home, it was the first shot of the 49 pictures I exposed during 8 intense nights, using 3 cams simultaneously.

Canons 300m f/4 may not provide ideal star forms, but it is lightweight and powerful enough to do a good job with lots of 2min Subs at Iso1250 on Eos6d.
