vdB 7 - vdB 9 - LDN 1355/57/58

This object is a series of objects located away in the constellation of Cassiopeia at a declination of +70 degrees.

The object in the upper left of the image is vdB 7, a reflection nebula next to the bright star HD 17138 (RZ Cass). The star that is illuminating the nebula is the weaker orange star to the right of the bright star. The nebula is only 200 light years away and is less than half a light year wide.

The reflection nebula just right of and above image center is vdB 9. This nebula is much farther away than vdB 7 at about 1400 light years. It is about 3 light years wide and is illuminated by the bright star at its center, HD 17463 (SU Cass). I find the structure of this reflection nebula to be interesting.

The dark nebula on the left side of the image is LDN 1358. The two dark nebula on the right side, close together, are LDN 1355 (larger) and LDN 1357 (smaller). I love how these nebula appear to be completely isolated from the surrounding brighter star field surrounding them, almost to the point of being lonely out there.

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.
