Between Crescent and Eta Cygni

Lots of amazing faint nebulae are hidden under the starry flow of the milky way in Cygnus. This shot captured area between the famous Crescent nebula NGC6888 and Eta Cygni. The Sharpless 101 "Tulip Nebula" located around the Eta Cygni is a good guide to find the famous X-ray source X-1 Cyg.

Unfortunate weather condition at the night did not allow me to expose as planned, totally 1 hour of both L and RGB images from cooled CCD camera and DSLR were captured though thanks to the dual telescope system. This shot is not a mosaic, then you can see the image form of the new APS-H sensor KAF16200 is amazingly close to square compared to typical rectangle APS-C sensors.

Detailed acquisition information is as follows:

[Exposure Time]

L Images:

2016/8/9 0:14-0:42

300 secs x 6 frames, total exposure 30 minutes

RGB Images:

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.
