VBD152 or Barnard 175

VBD152 or Barnard 175 is a blue reflection nebula on the tip of a dark nebula LDN1217. The red arc stretching across the image is supernova remnant arc SNR 110.3+11 with planetary nebula PN G111.0+11.6 near the right. I've collected close to 30 hours of exposure time for this object since starting this project last October. There are a few hours of 5 minute Ha subs I didn't end up using since I've replaced them with 10 minutes ones instead. This year I'm mainly interested in revisiting 10 hour projects I already have and driving them deeper. Taking this object from 10 to 27.5 hours helped reveal significantly more color and fine detail all around the image. Continuum Subtraction was used to add Ha to the R channel. Spectrophotometry–based Color Calibration was used to further calibrate the RGB channels. Deconvolution in the form of BlurXTerminator was applied to both RGB channels and Luminance separately before the final image combination.
The image was captured over the course of 6 nights between October 2022 until now.

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.
