Description

I started to use my Nikon 70-200 f2.8 lens and some results are quite nice to my eye. Here is a first publication around Deneb in Cygnus...
Do you see the man's profile with a red eye, on the right ? Once you'll see it, you will not be able to "not" see it anymore :-) Imagination is a funny item.
DATA :
18 x 300 sec. @ 1600 iso (200mm @ f2.8)
B VERSION : 8 x 300'' @ 1600iso : here it is in good focus but less density because I didn't catch more frames during that session. Just for you guys to compare.

NOTE : the f2.8 is sharp but it does bring much coma on the edges. This version is a little bit out of focus, but more detailed than one I did in 8 subs... What to do ?
