The Iris and Ghost Nebula

Back in August 21' I took an opportunity to begin imaging this wide field view of the Constellation Cepheus.

At the bottom of this image is the blue reflection nebula NGC 7023 aka the Iris nebula which is illuminated internally by the very bright star HD 200775. Above the center is a dark nebula vdB 141 aka the Ghost nebula.

Much of this region is brown/gold galactic cirrus which reflects light emitted by the milkyway. There is also alot of bluish reflection nebula illuminated by the very bright stars in this region.

I collected this data over 2 nights.
I shot 6.66hrs at my friends property in natural bridge. It got to a mag 21.4 that night.

I shot another 7.66hrs at my house which is in the suburbs, the darkest it gets here is mag 20.4 around 1 am.

I was able to get a good amount of color from this data but I may continue to add more data and re process next year.

Image specs :
Camera: ASI 2600MC at 0c
9/12/21 : Gain 0, 50 x 480s subs, 6.66hrs

9/30/21 : Gain 100, 600s x 46 subs, 7.66hrs

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.
