VdB 136 Yellow Reflection Nebula

Images from the following two scopes (piggybacked) contributed to this image:

AG12+ASI1600MM at .70 asec/pix (RGB)

TV127is+ASI183MM at .75 asec/pix. (L)

They were all registered to the best R image taken on the AG12.

This image was unguided.

The original version of this was just awfull! Why didn't someone say something. Somehow I deluded myself into thinking those colors were real. Actually I had a very bad color gradient and it took multiple applications of DynamicBackgroundExtraction to correct it. Color gradients are a real risk doing RGB with a full moon.

This image shows an unusual and rarely imaged yellow reflection nebula. Light from the red giant star in the center is being reflected in our direction by particles of soot and gas behind the star, giving the diffuse yellow glow of VdB136. The area is surrounded by faint H-alpha emissions and interesting dark lanes too. This patch of sky lies about 2 degrees from the Cygnus the Swan’s brightest star, Deneb. VdB 136 is a around 2510 light years distant.

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.
