M106 and nearby friends

Revision title: HaOiiiRVB

M106 captured over three nights.
RGB : ss stars were accidently burned during the second night because 300s is too much for good those nice stars under a good sky, the star layer is restricted to the first session, totaling 46x300s. The outcome is not as good as hoped for but not that bad either.
Ha/Oiii : In the final version, the RGB data are supplemented by Ha and Oiii data using an l-ultimate filter. Considering the size of the main object, the added value is not huge (compared to an object like M101 at the same focal length). However, the additional data brings a nice contrast to the center and the immediate periphery of the core of M106.

Description: In this new version, the RGB data are supplemented by Ha and Oiii data using an l-ultimate filter. Considering the size of the main object, the added value is not huge (compared to an object like M101 at the same focal length). However, the additional data brings a nice contrast to the center and the immediate periphery of the core of M106.

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.
