The Bubble Nebula is photobombed by M52. I wasn't sure I was going to like this framing but thanks to the gas extending to the edge of the frame, it made it all work out.

We had a rare stretch of five clear nights here in Virginia so of course, circumstances kept me from taking advantage of the first two but I did manage the last three. I wanted a target I could devote a good chunk. of the night two and it needed to be away from the still bright moon. When I looked at the possibilities there weren't a lot of choices. I had done the Bubble before on the SRO scope but this would be wider field and when I look back at that older version (which had some data problems as we were still learning how to use that CCD camera properly), I much prefer this version though I've learned more about processing since then so maybe I should reprocess that old data to give it a fair chance.

As it turned out, I liked this a lot. Though the Bubble is relatively small there's.a lot going on around it!!

Processing:

Each S, H and O:
blurXterminator
starXterminator
noiseXterminator
GHS (GH, linear, GH)

stars:
channel combination (SHO)
GHS (GH)

SHO:
channel combination (SHO)
histogram transformation (to align peaks and further stretch data)
SCNR (maximum mask)
noiseXterminator (those big stretches brought out a bit too much noise in the dark areas
LHE
MLT (mild sharpening)
pixel math in stars (screen)

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
