Jellyfish Nebula, IC443, Unmodified DSLR

I was looking for something besides galaxies to image from my back yard over a period of several days of clear nights. I decided to see what I could get with IC443. I was able to image a little over 1 hour each night before it got too low for a total of just about 6.5 hours. Not much time and not the right equipment for the full experience but I stubbornly stuck in there just to see what I _could_ get. And here it is! The Jellyfish Nebula is the remains of a galactic supernova about 5000 light years from Earth that occurred between 3000 and 30000 years ago. I am sure I'll be imaging this again when I have a camera that can do it justice.

Description: A couple of EZ Star Reduction and made an interesting mask for sharpening based on Green and Blue channels only (extract each, combine, then extract lightness). It's hard with the stock camera and I don't want to push too hard but I think it's an improvement in that it shows what I could capture a bit better.

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.
