Jellyfish nebula

Well, I am gradually getting used to this new scope 5.1" refractor, and its smaller field of view will be very useful for the up and coming galaxy season, hopefully. I know the stars are a bit misshapen on this, but I have worked out what to do now to solve this - he says! This was 65 subs at 5 minutes long each, right near a very bright moon. To give you an idea of what this meant - I could barely see the 'cap' of the jellyfish on the individual subs let alone any other parts to this nebula, so I was surprised how much detail was there after stacking. I also cheated - I cropped out the bright star! I could not be bothered to try and fix that as I am no good with bright stars... Anyway, this works out at an integration time of 5 hours and 25 minutes. I found it tough to process, but maybe on a moonless night, on another day, with some more imaging time, things may fair better. I am beginning to enjoy this new scope. Thanks everyone...

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.
