Dark Shark Nebula (LDN 1235) and PGC67671

I've done a little diving and am fascinated by the grace of the sharks I've seen (reef sharks so nothing ominous). So why not take a look at a shark in the sky? I've enjoyed others' images of LDN 1235, the Dark Shark Nebula, so thought it was time to take a look myself. This is what I have at the moment with the FL156 and 5hr 45min integration, imaged when the sky quality reading was close to 21 from my backyard in Lowbanks, Ontario. I wanted to see what sort of detail I could pick up with the big refractor, particularly what kind of resolution of PGC67671 (the galaxy photobombing the nebula from 58 million light years away) I could get with my setup. If you imaged this, you know that it can be tough to frame, and with the FL156 given the field of view and the fact that the nebula itself is, well, dark and it's not in NINA's Sky Atlas. But once I brought the coordinates in from Stellarium the framing was a cinch. This one is a lot of fun to work on! I've edited this 3 or 4 different ways and this is my favourite at the moment.

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.
