I did note that I would try to analyze subframes in the last post, but I thought it was worth a shot to take some pictures. The target was NGC 6974, one of two luminous knots within the Veil Nebula. It was particularly tricky because of the scattered clouds in the evening. It started fine, with the polar alignment taking almost no time at all. Focusing with SVBony’s SV220 Ha+OIII filter was not challenging at all. Once I slewed to the target things got worse. There were scattered clouds hindering the guiding, so I waiting a bit until they passed. Once they had passed, I continued the guiding assistant in PHD2 and then realigned on NGC 6974 to start guiding. I had to interrupt the session while clouds came in, then started it again when they passed.
Observations
On first glance, NGC 6974 is barely visible with my imaging setup and the duo with NGC 6979 seemed oddly framed. NGC 6974 was in the middle and NGC6979 was off to the side. This won’t be an exceptionally framed capture, but I had never shot this target and wanted to see how it looked.

Images
The image here was a quick stack and process to get the image to come out. This is about half the time that I would like on target with this filter. There’s no cropping and all defaults were chosen when running PixInsight processing.
