It looks like Carlos and I were thinking similarly this last week as we both spent time capturing part of Rho Ophiuchi, the Antares Region as I call it.
My goal was to get the M4 Globular Cluster, I will crop in for a tighter view of it later, but this was my view at 500mm. I limited myself to 60 second exposures as it was 96 degrees out during the day and down into the 70's at night in the Bonneville Salt Flats where I stopped to capture this and the Milky Way on my way to Colorado a few days ago. With it being so warm out, I didn't want to take any chances with the sensor getting too warm from the longer shutter speeds and causing noise.
SkyGuider Pro - Tracking
Nikon D850 - Not Modified
Tamron 150-600mm @ 500mm
22 - Lights @ ISO 800, f6.3 and 60 seconds
5 - Dark Frames
I probably could and will work on this some more later. But with babysitting 6 grandkids here, my time is limited to be able to really focus on processing.
All comments are welcome,

PS. the M4 Globular Cluster is the cluster of stars in the middle on the right side. There is a smaller Globular Cluster above the Antares star that I could not find the name for.
