Description

A three-image-mosaic of the surroundings of North America Nebula. Single exposures, no stacking. Canon EOS 6D, ISO 3200, 30s, EF 100/2 @ f/2.0.

The 100mm lens seems to have very even field even wide open and coma can be found only in the extreme corners. Unfortunately brighter stars have ugly fringe in them, but most of it goes away @ f/2.8.

Stitched with PTGui Pro. A version as-is, B version with slight fringe kill in Lightroom.
