Jellyfish Nebula

A rework of the Jellyfish with new data added as well as new processing techniques. 25Hrs of 20 minute exposure to go in deep and highlight the Oiii sheathing the head of the jellyfish.

Note the small planetary nebula in the upper left, named HoCr1 (Howell-Crisp 1, discovered in 2006 by amateur astronomers Michael Howell and Richard Crisp). This is just 73" across. I do need to reprocess this to pull out the PN with optimal deconvolution as the decon result I achieved was messed up by star removal - so I dropped in a non-deconvoluted version with a predominant Oiii bias, losing the detail which I think is there in the Ha; I'll try drizzling it to see what I can pull out of it.

Rendered as a blend of SHO PIP and HOO PIP, with wideband stars.

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.
