LBN 683 and IFN

LBN 683 is a cold, molecular cloud in the northern sky near M81/M82. It’s listed in the Lynd’s Bright Nebula catalog as a brightness of 6, or “barely detectable”. Emission nebulae contain ionized gases which emit their own light. Reflection nebulae are clouds of gas or dust that are illuminated from nearby stars. But molecular clouds are usually not near sources of light or heat so they are cold enough to allow gas molecules to form, and are only faintly illuminated from the diffuse light of distant stars in the galaxy.

This one was extraordinarily dim and took over 32 hours of exposure over 5 nights to get this image. There’s not a lot of information available on the internet regarding the size, distance, etc. of these kinds of clouds. But they makes for an interesting image. This image covers about 4° of the sky horizontally.

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.
