IC410 - A Test of PixInsight's SpectrophotometricColorCalibration in Narrow Band Mode

This is IC410 in Auriga.

It is not the final image. It's a test of the new PixInsight SpectrophotometricColorCalibration process. It is primarily intended for RGB images, but it includes a narrow band mode. There have been some comments that the narrow band mode does not do a reasonable color calibration, so I wanted to give it a try.

This image was made from a subset of a full project (which I've not yet processed). I collected a full set of data, including R, G, B, Ha, OIII and SII, but for this test, I just used the Ha and OIII data. The details are as follows:

Telescope: Astro-Physics AP130GTX
Mount: Astro-Physics AP1600-AE
Camera: QSI 690 wsg-8 with Astrodon 3nm filters
Capture Software: NINA with Astro-Physics Tools Plug-In and Dec-Arc Tracking Model
Subs: 47x600 Ha, 49x600 OIII

Processed with PixInsight.

Since this was a test of SPCC, processing was minimal. I applied MureDenoise to the Ha and OIII channels. I combined them with Ha in the R channel, OIII in the green channel, and OIII in the blue channel. I then applied SpectrophotometricColorCalibration in NB mode. Finally, I applied a slightly dimmed auto STF. There was no other processing.

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.
