Revision title: M81/82 Core Fixed

So I have tried stacking before using PixInsight but never seem to work but I decided to have another go and after some help from YouTube tutorials and the kind people of Astrobin I was able to achieve stacking multiple nights in PixInsight. First I used Blink to blink all the images from the previous image of M81/82 I uploaded here and I had to delete over an hour of light frames. I saw a post here about Generalised Hyperbolic Stretch and my goodness that script makes a huge difference compared to stretching with the normal histogram. I removed the stars to work on them separately then added back together using Bill Blanshan's rescreening scripts. Cores are a bit blowned out so I will need to shorten my exposures next time. I'm currently working on the Ha data and will be combining it with this data.

Title: M81/82 Core Fixed

Description: The core was a bit blowned out on my original image but got it fixed by applying the GAME script as a mask and used the Generalised Hyperbolic Stretch

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.
