Description

Originally intended to capture this as a 3-panel mosaic using my ASI1600 last year. Probably a good choice to delay it until I upgraded to a 6200 considering how many nights would have been required. Not sure I like the framing on this (one large nebula on each side looks odd) but I couldn't justify rotating the camera to only capture one of the nebulae.
