Description

Quick test of a Tamron 17-50mm zoom lens @ f/5.6 with my ASI1600MM.

Used gain=76 offset=50 T=-10C.

Had thin scattered clouds come through frames during exposures but since they were moving seem to have mostly "averaged out" when stacked.

Saturn is the bright object at the bottom of the image.
