IC443 Ha-SHO-RGB

IC443 named also the Medusa is a nebula that originated from a supernova event that took place thousands of years ago. NASA’s latest research estimates the age of this supernova remnant to be tens of thousands of years, which aligns with previous work that estimated IC 443 to be about 30,000 years old. IC443’s true age remains in question, as other scientists have inferred much younger ages of about 3,000 years.

I shooted this picture by accumulating a lot of Ha images, so to enhance the very faint Ha regions around the core of the nebula. I decided to stop after accumulating nearly 20hrs integration of Ha signal, but I think that one may easily go to 50 hrs to capture the deepest details of this fascinating nebula. I was BTW suprised by the strong intensity of the SII signal.

I hope that you will enjoy this new version among the hundreds already shooted by many valuable astrophotographers.

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.
