Sh2-140, not a very familiar name but certainly an amazing target for this time of the year. In this image you can see three different nebulas, emission, dark and reflection. The emission Sh2-140 is caused by the radiation of young stars in the star cluster Pismis-Moreno1. A bow shock (bright rim) is formed due to the radiation towards the dark nebula LDN1204. This dark nebula divides Sh2-140 from Sh2-145 which can partly be seen in the upper left corner of the image. The small blue reflection nebula on the right side of the image is catalogued as GN 22 12.3.

It took me almost 30h of image acquisition, between HRGB filters, to get this image where I wanted. The Ha was done in the city and the RGB in dark skies.

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.
