The constellation Eridanus hosts many nebulae, and LBN 917 is one. It lies west of the Great Nebula in Orion, and is considerably fainter. LBN 917 has not been much studied and, consequently, little is written about it. Apparently, it is a bit of a hybread HII (red) and reflection nebula (blue), as well as passive areas (brown or gray). In fact this deep-sky object is seldom imaged, even by amateurs. However, it commonly occurs in stock-photo collections and even on a tote bag, where it is commonly mislabeled as the “question mark nebula” or the “Wolf nebula.” I have not found a widely accepted name for this cloud. I think I’ll call it “The Incognito Nebula”.

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.
