12/28/2022 – EAA – Just Some Open Clusters

Another nice clear night. A little bit warmer, mid-40’s at the start of the night and just about freezing when I covered up the scope. There were some high thin clouds but these cleared out just after dark. I was hunting open clusters, mostly in Perseus, and I found a bunch of them. I limited my time on each object to 15 minutes.

Just after dark I did a visual polar alignment. Only needed a minor tweak from the night before. I did shoot a new set of 60 second darks since there was an issue with the ones I shot last night.

The EAA images in this post were capture with my ZWO ASI294MC Pro cooled to -10 C through my SVBONY SV503 102ED scope with 0.8 Focal Reducer and a SVBONY IR/UV Cut filter. Focus was obtained with the ZWO EAF using the Ekos Focus Module. The images were live stacked using SharpCap Pro. The mount and cameras are remotely controlled with KStars/Ekos with INDI Server running on a Raspberry Pi. The images have been resized (80% of original) and/or cropped for file size but otherwise appear just as I observed them.

Each of these EAA captures is a live stack of first 10 x 30 second exposures and then 10 x 60 second exposures at 121 gain, 8 offset, and bin 2×2.

I packed up and covered the scope at around 10 PM. A fun night looking at open clusters.
