LBN 640

This object is a dim reflection nebula located in the constellation of Perseus at a declination of +54 degrees.

This object came to my attention when it was written up in the October 2019 Sky & Telescope magazine (p 59). I can't believe that this nebula was presented as an eyepiece object. I don't see how this could be seen visually when I struggled so much just to obtain some type of image of it. The stars are blown out above because I had to stretch the image so much to see the nebula.

The brightest area of this object looks like a combination of a blue reflection nebula with a faint cometary nebula, but as far as I could tell this smaller region of LBN 640 has no specific designation, which surprised me. A faint HII signal runs throughout the nebula, adding a nice subtle red hue.

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.
