Thanks Joe, glad you liked it.
Basically it was a quick test shot on a tripod, no tracking, to see what I could capture.
That's why the trees are like that, it was stacking the eight slightly rotated sky images that resulted in a blurry tree line.
Even at 30 sec, it's so surprising, as you know, how much the sky moves even at wide 16mm full frame.
I knew I was pushing it with the
'500 rule'.
The stacking program I used, Registar, does a wonderful job in registering and aligning the sky, but the tree line suffers.
If I was to do a proper nightscape, I'd also do one exposure just for the foreground and blend the two, but I was only at home without an interesting foreground.
Cheers mate, thanks for the feedback.
Next time at the PC, I'll try and get a tracking shot with my plateform and a foreground.
