NGC 598

In an unplanned attempt, I diverted to this galaxy after my actual target LBN406 in the Draco region had set behind my visible field of view in the north. With the waning crescent moon in close proximity to the target, I decided to give it a try nonetheless that early summer morning.

Within our local group this galactic neighbour is spiralling clockwise from our perspective with an approximate revolution of 200 million years. With its largest ionized hydrogen region known as NGC604 that is showing in the red spectrum visible in the arm on the right side of this image, this galaxy is thought to have crossed its path with M31 some billion years ago.
Being my first try on imaging/processing a galaxy with my telescope and despite the short integration time, I wondered what may be revealed from the data I obtained that morning. Any critique and suggestions for improvement are well appreciated.

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.
