The square 'Antares - M4 - Alniyat - IC 4605'
The 'square' covers a number of interesting objects (see Annotated version as well), such as Alniyat (part of the Sigma Scorpii star system) on the left side of the photo. Then we have the globular clusters M4 (brightest cluster, top of the photo) and 1° away to the right we have the NGC 6144 as well. To the right, at the edge of the blue zone we have Antares - the brightest star in the constellation of Scorpius. At the lower end of the photo we have 22 Scorpii (also known as IC 4605).
Overall very interesting area, and tricky to process, based on 90 mins total exposure and a lot of processing effort due to the high resolution of QHY 600M (not complaining ;), just took a few more extra hours compared to anything else I've processed so far). Both PixInsight and StarTools were taking a long time for every operation! It was joy though. Since I've only joined Telescope Live a week ago, this was an awesome challenge! I hope you like the result!
Have a look at the other versions I've attached as well - simple annotated version, heavily annotated version and a flipped version, which also happens to be more starry (less applied StarXTerminator effect).
