Description

Captured with nikon d5600 unmodified, Tamron 70-300 @300mm, 40sec expos. (it is 450mm on the crop body)

During 2 nights I captured more than 400 lights, and I got 175 keeper images. From that I stacked the 140 best.

1h41m total exposure time.

Bortle 4 backyard.

Iso1600 with f5.6 and iso2000 with f7.1 on the other night.

This lens is a lot sharper at f8 so the second set made the stack a lot sharper.

Let me present to you my version of the M101 - Pinwheel galaxy.
