W63 SNR in Cygnus, HSO + RGB

W63 is an elliptically-shaped supernova remnant in Cygnus. The remnant is faintly visible in Oiii light and is engulfed in a fairly bright region of H-alpha emission nebulae. Its distance from Earth is estimated at 5000 light years with the shell diameter measuring 150 light years across. Light from the exploding star would have reached Earth over 15,000 years ago. So far, no progenitor star has been identified.

In mid-April, I began collecting Oiii data when the target was rising above 30 degrees in the east at 3 AM. I imaged for 13 nights over a 1-month period to collect all the data for the narrowband and RGB channels, putting half of the emphasis and effort on the Oiii channel data to compensate for the faint signal. The three narrowband channels were combined in the final image using an HSO color palette. The stars were removed from the NB channels and the RGB data was used for the stars in the final image.

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.
