Lion Nebula and my myriad of mistakes

You ever wake up and just say what a week I am having! This image has been a huge challenge and mostly because of me. First night I captured about 5 hours of data using my UV/IR cut filter, but I guess my skies aren't dark enough for an emission nebula as I had very little detail or color. Second night I captured about 7 hours of data with my NB filter (much better), but lost 2 hours due to clouds rolling in. Also, I had some strange streaky noise in my first stake. Figured out is was bad darks, so I had to make 30 more 5 minute darks (a 2 1/2 process). Also, I forgot to switch my Autorun capture from Flats to Lights and FYI, I just learned that the ASIAir Pro only dithers when Lights are selected, so my dithering was disabled, so I still have more noise than I would like. Then last night, I captured 175 2 minutes exposures (shortened up the time, it was pretty gusty) and they were looking great, stars were round and dithering was going great, but somehow I overrode and lost all my images, I still have no idea what I did. Anyway here is my current Lion Nebula ran with new darks, just the NB images. You can kind of see the lion, head to the left, tail to the right.

This nebula AKA Sparpless 2-132 is in the constellation Cepheus and is around 1,700 light years from our solar system.

Description: Someone provided me a link that helped me restore 90 of my exposures from the other night that were deleted from my USB drive. I incorporated these into my image train and I think it did help get a little more detail.

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.
