NGC7000

Revision title: NGC7000 pseudo HST

Shooting in narrow double band with color camera. L-Extreme filter and QHY294C.

NGC 7000 is an emission nebula in the constellation Cygnus, located near Deneb (α Cygni), which is also called the North America nebula. The dark central region is called the Gulf of Mexico, since in some astronomical plates from many years ago it resembled that region of the Earth.

NGC 7000 is a large nebula that covers an area equivalent to the full moon, but its low surface brightness makes it normally not visible to the naked eye (however, on a dark night and with the help of a UHC filter it can be seen without optical aid ). NGC 7000 and the nearby Pelican Nebula (IC 5070) are part of the same interstellar ionized hydrogen cloud (HII region). The dark area in the center is a very dense region of interstellar material in front of the nebula that absorbs the light from it, giving the whole its characteristic shape.

The distance that separates us from NGC 7000 is not known with precision, nor is the star responsible for the ionization of hydrogen that produces the emission of light. If, as some sources point out, Deneb is the star that illuminates the nebula, the distance of NGC 7000 from Earth would be of the order of 1800 light years.

Title: NGC7000 pseudo HST

Description: This is a salvage RGB image from October 2021, processed towards Hubble's false palette. Originally the image was taken in RGB with a QHY294C color camera and a narrow-pass (HO) double-band filter, H for the light emission frequency of hydrogen and O for oxygen, the main components of this stellar gas cloud. For this I have used the script ( HOO normalitation) by Bill Blanshan for Pixinsight.
Images taken last year in October 2021 of what was originally an in-camera RGB palette. .

19 600sec shots with a (small) 72mm double apochromatic refractor telescope with focal reducer up to 0.79x from Vega Observatory in Ager, Lleida.

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.
