Propus and the Jellyfish SNR (IC 443)

A quiet, clear night allowed me to try a dimmer object with my new gear. The Jellyfish Nebula is indeed quite dim and the nearby influence of the bright star Propus (η Geminorum) made exposure levels a bit tricky. Still, with all my imaging, I care more about accurate star color than anything else, so I made sure Propus and the other stars got the proper treatment. Propus is actually a triple star system and the most luminous star is a cool M2IIIa red giant star which overshadows the other two stars.

The Jellyfish Nebula itself is a supernova remnant and I had to do much more stretching than I like in order to pull it out from the darkness. Longer exposures, I'm told, would be a better option for any future attempt.

This is only my third imaging session with all new gear, so I am still taking baby steps, but with this effort I feel myself getting stronger.

Clear Skies to all and thanks for stopping by to read, look and comment!

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.
