The Cygnus Wall 

C20, NGC 7000

Cygnus

28/08/24

Here's my go at Caldwell 20, the North America nebula or more specifically, the Cygnus Wall part of it. Seems to be a popular target this week! I captured data over two nights, 2 hours on 26/08/24 and 7 hours on 27/08/24. The first session was intermittent cloud so I didn't use any of it in the end. The second session was very clear all night long. While I was at it I did an All Sky Video of the night sky. 

54 x 240 seconds Luminance, 17 x 240 seconds RGB. Stellarium, Pegasus Unity, CPWI, NINA, PHD2. Stacked and Processed in PixInsight. The colours are a little unexpected but the Photometric Colour Calibration Process seemed happy with it.

I'm getting right into Open Star Clusters! Here is the first on Patrick's list. An Open Cluster with another one behind it in the distance and then another one behind that at an even further distance!

The Intergalactic Wanderer 

C25, NGC2419

Lynx

Globular Cluster

Well the full Moon bleached everything out as you would expect. But when the night sky is clear you got to do what you got to do! I was tricked by the low humidity and forgot to turn up the percent aggression on the dew controllers for a close to zenith target so copped some condensation. But I didn't want to over process it and loose the detail of the glob. So here's a suboptimal Caldwell 25, the Intergalactic Wanderer. I was going to rotate the camera to get a nice horizontal conga line but I had already calibrated the guiding and didn't want to move it!

NGC6946 - Spiral Galaxy

Caldwell 12

Cygnus

06/09/23

Here's Caldwell 12, NGC6946, the Fireworks galaxy. Captured over three nights this week and last week, each time packing up before the night was over, due to the high humidity causing USB connections failures!

My last attempt at this target was a couple of years ago on fireworks night!

This galaxy was one of the targets in the TSS Monthly Challenge. It also won the TSS APOD award for 11/09/23
