Revision title: M101 (Northern Pinwheel Galaxy) with Ha-starbirth centers

Same base image as shown before, a few days ago but this time, I was able to add Ha to the RGB image. Last night, the skies were nice to me - for about 3 hours, before fog set in, and so I was able to get 57x180sec subs with a newly developed L-extreme 2.0 filter for RASA applications. The result is quite fine, showing nicely the Ha emission centers.

Technical data in general as before---- RASA11 with ASI183MC on a CEM120EC2 mount. Processing in PixInsight and Photoshop.

Since the base image (RGB) was existing - see my gallery - I did not declare again its technical data.

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.
