This image of a part of the Milky Way/Sagittarius region was imaged with a QHY268M and a Sigma 80-400mm EX zoom telephoto lens at 80mm focal length on the nights between 25th June and the morning of 9th July 2022.

Sagittarius is a large constellation located south of the ecliptic, FOV near toward the center of the Milky Way galaxy.
This constellation is in a region of the Milky Way which is rich in gas and dust as well as various nebulae and objects through out. Objects such as the Omega, Trifid and Lagoon nebulae... full list of objects detected in Astrometry.net listed below.

The total integration time for this image was 14 hours and 52 minutes of subs, 54 subs each of 90 and 180 second for Luminance, and 100 x 60 second subs for the red channel, 71 x 120 second subs for the green channel and 64 x 180 second subs for the blue channel for the broadband data and 43 x 300 second H-Alpha subs to emphasize the Hydrogen Alpha signal in the frame.
