Backyard - IC 443 - A Galactic Supernova Remnant

RASA8 project hit a pause. The Chroma 5nm filters do not suit for F2.0 system at all. Now going back to the Astronomik 12nm filters as the F2.0 system narrowband solution. Waiting for ordering from Astronomik once confirmed.

Too much fun to image within 30 degrees of the bright moon. And of course, as poor as the SNR could be - especially the O3 channel. To my surprise, even Ha master got strong gradient because of the moon. Never did DBE for Ha master before. 🤣

But, lots of fun this time in color blending - with PixelMath boosting the super low SNR O3 channel. No Photoshop color match-making this time. Except the export, all done in PixInsight.

Pre-processing of Narrowband Masters

– MultiscaleLinearTransform (Denoise), PixInsight
– ScreenTransferFunction / HistogramTransformation, PixInsight.

Pre-processing of RGB Masters

– Calibration / Integration, Astro Pixel Processor
– Dynamic Background Extraction, PixInsight
– MorphologicalTransformation, PixInsight
– ScreenTransferFunction / HistogramTransformation, PixInsight.

RGB Combination

– LRGBCombination, PixInsight
– MorphologicalTransformation, PixInsight
– ScreenTransferFunction / HistogramTransformation, PixInsight.

Narrowband Combination

– PixelMath, PixInsight (Fun! Fun! Fun!)
– ScreenTransferFunction / HistogramTransformation, PixInsight.

Narrband & RGB Combination

– PixelMath, PixInsight (What layer blend?)
– Final Export, Photoshop

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.
