This is my next attempt on M101, this is as M81 not an easy one. I should have learned that 2 minute exposures just don't do this galaxy good. I had an hour of 300s luminance and it helped, was just not enough. I will give it in my future one more time with a new scope and mount, and maybe I have to go to a dark spot as well, all stars need to line up for me to have at least a chance to make a nicer image. And I need to go to some school of galaxy processing, watched several already on YouTube but so far I cannot get it to click. Some Hα might be not bad though too! Oh and I almost forgot ... man, those gradients in the images were awful! Read through the PI lesson on how to get rid of them the best way, oh my, I do need another scope for that and take some more images of M101!

P.S.: Rodd, please don't compare with yours 😊😊😊, yours is magnificent!

Description: Added more Lum and gathered some Hα data. To make the image better I would need some more RGB data, especially G data, for some reason the current set of G data sucks ... 😉

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.
