The False Comet in False Color

When Charles Messier was looking for Halley's Comet, he kept coming across a fuzzy patch he realized didn't move like a comet. So, he started a journal of these annoying distractions and designated the fuzzy patch "M1." Ages ago, a massive star spent the last of its fusion fuel and experienced a massive implosion that happened so fast, the inner part of the star sent shockwaves that ejected the outer portion. When the light eventually reached earth, it was so bright it could be seen by day for several years. References around the world have been found for a "wandering star" that suddenly appeared and eventually faded.

I trained my telescope on the spot and recorded photons for 12 hours. I took 3-minute exposures in the red, green, and blue spectrums and combined them for the first image. I also took 5-minute exposures of hydrogen alpha and oxygen III emissions and 7-minute exposures of sulfur II. These mapped to a SHO palette and blended with the visible light data.

Everything was captured using a ZWO 294MM Pro in the "unlocked" bin 1x1 mode at 8k by 4k resolution, then cropped to spotlight the nebula.

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.
