Finns Nebula is an unknown and uncatalogized reflection nebula around the variable star BE Cam (V* BE CAM, HIP 17884) in the constellation Camelopardalis. It has never been photographed before.

Finns Nebula is a very rare orange-yellow reflection nebula of the Merope type, because it reminds optically strongly of the nebula around the star in the Pleiades.

Because Finns nebula is located around a variable star, its brightness varies periodically analogous to its central star. This makes Finns nebula an extremely rare yellow, variable reflection nebula.

With an extension of 30-40 arc minutes, the reflection nebula is very large, but extremely weak in brightness.

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.
Dismissals 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.
