Orion to Andromeda (lefty7283)

Orion to Andromeda

I captured this to serve as the background panels for [project patchwork](https://www.reddit.com/r/astrophotography/comments/dlz1zb/happy_10th_birthday_rastrophotography_and_an/). Good thing they're going to get covered up in the final mosaic, as the lens distortions and the streetlamp just below the FOV really don't help this image. **[I've also made an annotated version highlighting all of the Messier and NGC objects in the FOV](https://i.imgur.com/6rosNOG.jpg)**. Captured on December 19th 2019 from a bortle 6 zone.

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.
