Lobster Claw and Bubble Nebulas

I saw a nice image of the lobster claw nebula the other day, so I made it my next target. When composing the image in SGPs framing wizard, I noticed this other nearby nebula and when I zoomed in, saw it was the bubble. I changed my plan and installed my focal reducer so I could capture both at once. I think the bubble in this image is better than my stand alone version capture w/out the reducer.

Once the moon is no longer an issue, I'll grab some RGB and replace the stars with RGB stars.

Description: Ok, grabbed some RGB stars a while ago, but only just now got around to processing them. There were 10x180sec of each RGB and I used ArcsinhStretch to initially stretch to to preserve color. I further stretched them with HistogramTransformation, leaving them smaller than what I had the NB image as I find all those stars in the milky way to be distracting. I also tweaked the color a bit as I was at it.

Description: Looking at the new revision again, I see I. blew out the core of NGC 7538 and the bubble a bit, so dialed back the stretch on those a bit.

Description: While waiting for another target to rise high enough, so I decided to get more data for this image.

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.
