The Crescent & Gamma Cygni Nebulae

A very deep and Bi-Color view of The Crescent and Gamma Cygni Nebulae using H-Alpha and OIII filters covering 4.01 x 2.62 degrees of sky. I was so pleased with the resolution I produced the same image with a zoom view of The Crescent increased in size by approximately 260%

Captured from my amateur backyard observatory in Fremont, Michigan using a QHY11 Monochrome CCD/Takahashi E-180.

Total Integration Time 3.3 hours

Not your ordinary planetary nebula, which are produced when sun-like stars enter the last phase of their lives by becoming a red-giant and subsequently shedding their stellar atmospheres. The Crescent is, like other planetary nebulae, being ionized by it's parent star's intense radiation, but unlike most other planetary nebulae, The Crescent is also being ionized by the nearby Wolf-Rayet star "WR 136" whose intense winds are colliding with the material blown off by the Crescent's parent star. The end result is a beautiful image of two distinct shock waves colliding with each other in the depths of space, heating the gasses to temperatures so extreme that it emits X-ray radiation in addition to wavelengths within the visible spectrum of light.

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.
