With new data added to a second panel and also an additional hour of SII, Ha and OIII subs for last year's panel, I have re-processed from scratch this two panel mosaic of LBN 251. The FOV has a strong diagonal interest with bright emission nebula as well as dark obscuring dust and is a fascinating region in Cygnus. Last year's image for reference is here https://www.astrobin.com/f7gptv/.

There is a small bright blue planetary nebula, designated PN G077.6+04.3, and located about half-way down the frame on the rig-hand side, has an apparent diameter of just 45", and was discovered quite recently in 2006 (www.cosmicneighbours.net) and its Simbad reference page is here (http://simbad.u-strasbg.fr/simbad/sim-id?Ident=%4091015&Name=PN%20G077.6%2B04.3&submit=submit).

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.
