Bubble Nebula Region in RGB

Imaged the region around the Bubble Nebula (Sh2-162) that includes the cluster M52 and the Lobster Claw (Sh2-157, barely visible at the top, right edge of the frame) on the nights of November 24 & 25, 2019. The bubble near the center of Sh2-162 is just visible. This is a pretty interesting field with a lot going on. I took some narrowband data that I still need to process, but will need to revisit this region to add more RGB data in the future. Also, the focus is a bit soft in this image, autofocuser on the way to hopefully improve that long time situation...

Imaged with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer, IDAS LPS D1 Clip Filter, and full spectrum modified Nikon D5300.

Pre-processed using PixInsight Batch Pre-Processing (BPP) script. Images calibrated using darks, bias, and flats. Stacked 112 subs (180 sec at ISO 200) for a total integration time of ~3 hours. Post-processed in Pixinsight: Cropped, gradient removal with ABE, MLT for noise reduction, Photometric Color Calibration, stretched using masked stretch, Curves Transformation, ACDNR for noise reduction, Morphological Transformation to shrink stars, Local histogram transform, and Color Saturation boost.

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.
