M109 had a complex and travailed gestation history and that should be no surprise to anyone who is following my imaging thread. In fact the said gestation period is mostly likely to go on for quite a long time further. However it felt right to issue this image to close the door to a certain period and possibly usher the next one, so to speak. Th image started in 2009 but I found it hard going despite the clearly advantageous position in the sky. Caught up it again in 2011 to a better overall luminance (but still somewhat lacking at that image scale) but, despite the effort, something wasn't quite right with the colour integrations. Cue to 2020; I am reprocessing the whole lot and still can't get my head around it no matter they way I turn and twist the data. Decided to give it another go with my recent hardware and hopefully get a better colour. And here is the final result. Any new image of M109 will be done without recycling any old 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.
