M101 - RASA 8 - RGB - 20 minutes imaging time

It is possible I might get a clear night today, so I thought I would try and complete this image and get it done, before I probably need to do some more processing tomorrow and over the next day for the next data set - weather depending. Two nights ago I tried to take 4 hours worth of this object, but the weather simply failed me and all I got was 10 subs, each at 2 minutes long exposure time, and 5 of those subs were really not very good at all. So, 20 minutes integration time! I had to be really inventive with dealing with haloes and high murkiness across the image, so that I could get something out of the data. I am pleased with this image for three reasons: (i) I actually got an image on a night when I should not have done, (ii) it is incredible how fast the Rasa really is, and it still amazes me... even though I've used it a few times now, and (iii) this picture looks more like something that takes around 5 hours integration time, based on a comparable picture from several years ago, when I had a lowly 8 inch f4 Newtonian. I would like to think my processing skills have improved since those days, but even so, the Rasa has been the best purchase I have ever made, astronomy-wise. I hope you all agree. Many thanks everyone and I hope you are well.

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.
