A Ghostly Bok Globule

At approximately 18 x 9 arcmin, the Ghost Nebula is a small target for the Esprit 100's focal length of 550 mm. Designated Sh2-136 in the Sharpless catalogue of H II regions as well as VdB 141 in Sidney van den Bergh's catalog of reflection nebulae, the Ghost Nebula is also designated as a Bok Globule ( Bok globule CB230) that is located in the same star-forming region (the Cepheus Flare molecular cloud) as the much larger and brighter Iris Nebula. Interestingly, when I imaged the Iris Nebula last year with a modified DSLR, the Ghost Nebula itself was a small and indistinguishable smudge; better camera and added imaging time (nearly 11 hours versus a little over 2 hours) have at least revealed some detail. Still, I can hear the cautionary note of other respected astrophotographers: I probably have not "earned the right" to display the data I am trying to show at this crop level. Need a bigger scope!

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.
