IC443 - Jellyfish Nebula

Hey,I would like to present to you my winter struggles with the weather. The hero of my picture is the Medusa Nebula. I was collecting material for it practically from December to the beginning of March. The conditions this winter were extremely unfavourable, which affected the visibility of oxygen in the nebula. Composed in the SHO palette.A little information about the object itself: IC 443 was discovered on 25 September 1892 by the German astronomer Max Wolf. Because of its appearance, the nebula has been named the "Medusa Nebula", not to be confused with Abell 21. Unlike Abell 21, IC 443 is a supernova remnant and not a planetary nebula. The pulsar wind nebula with the neutron star CXOU J061705.3+222127 has been identified as the source of the supernova. A jet-like structure has been discovered in IC 443, which appears to originate from a neutron star. The distance to IC 443 is about 1.9 kpc (6200 light years) and its age is estimated to be about 30,000 years.The image consists of Ha: 220x300s, Sii channels: 104x300s, O3: 89x300s. The disparity is mainly due to the fact that I avoided collecting oxygen while the moon was towering high or its visibility was above 50%. The stars are a mixture of SHO with a minimally altered ratio to nebula.Material collected with SGP, stak and processing in PixInsight, resize to 4k px on the long side.

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.
