Description

This is a 9-frame mosaic, taken in six nights from Dec 2016 to Feb 2018.

Ver.A (the final) is a version with stronger contrast stretch to bring out the faint nebulas. Ver.B is a standard version with a more natural look.

The original image has 345 mega pixels. Here I upload the 40% reduced versions, for the sake of file size. Later I will probably upload a larger image to Gigapan or somewhere else.
