Helping Hand Nebula (LDN 1355, 1357, 1358)

This area of the sky is located between Cassiopeia and Camelopardalis but is technically part of Cassiopeia. The hand or dark nebula LDN 1357 appears to have been caught in the moment after star SU Cas slips through its dusty fingers. SU Cas is wreathed in a bluish reflection nebula vdB 9. Two other named dark nebula appear in this image: LDN 1355 is located in the wrist of the "hand" and LDN 1358 would appear on the arm or shoulder of this spectral appendage. The colorful reflection nebula at the lower left is vdB 7 and is illuminated by RZ Cas.

As a science fiction fan, this cosmic hand reminds me of the alien hand throwing galaxy marbles at the end of the first Men in Black movie. https://sm.ign.com/t/ign_za/screenshot/t/the-final-/the-final-alien-in-the-first-men-in-black-movie-is-only-glim_txuv.1080.jpg

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.
