Processing an Angel Close-up: RASC Robotic 0.4 m Telescope Data

NGC 2170, the Angel Nebula, is officially a reflection nebula, however, it is mixed up with red Halpha emission and dark nebulosity resulting in the incredibly beautiful and colorful combination that we see here. The Angel is 2400 LY away and thus an impressive 60 LY across!

Processing
I calibrated, registered and stacked all raw image with DeepSkyStacker. I used Startools for background correction, a 50% bin, digital development, HDR and initial color. I finished my processing in Photoshop with StarXTermintator to remove stars, AFP-R (used by NASA) for multi-scale unsharp masking, and NoiseXTerminator for noise reduction. Selective color and color channel mixing were used to optimize colors, then stars were added back in with a linear dodge (add).

Data
The image data is from the Royal Astronomical Society of Canada Robotic Telescope, Sierra Remote Observatories and was taken Oct-Dec 2021. The data included 5 hours of luminance (20x15m) and 5.5 hours of total RGB (11x10m each) with a 2x2bin. Darks and biases (used for dark flats) were also used.

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.
