My first image on Astrobin and my first completed image after moving all of my gear to West Texas to be hosted in an observatory in the Davis Mountains. 42 Hours of HaLRGB on a widefield image of M101 and the surrounding satellite galaxies and background fuzzies. With the ultra dark skies, bringing out the fainter outer arms of M101 was much easier, and something I haven't seen a whole lot with most amateur images of this object. Lastly, the Ha enhancement really helped add a nice pop to the spiral arms, and I am happy with how it turned out, seeing as it was my first time attempting this addition.

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.
