The towering Trunk IC1396 "Starless version"
The Elephant's Trunk nebula is a region of ionized gasses located in the constellation Cepheus at a distance of 2,400 light-years from Earth. Of interest in this area is the population of very young newborn stars, whose intense stellar winds are excavating the interior of the nebula. Dark wisps of dust hide the cocoon of forming stars, called "globules", which will be blown away when the star ignites.
Captured recently in Narrowband and Broadband using a QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on a Takahashi 130 FSQ, courtesy of QHYCCD.
This setup is available immediately for people wanting to subscribe to Grand Mesa Observatory's system 1.

In this Hubble Palette version (SHO) the H-Alpha is mapped to green channel, SII is mapped to red channel and OIII is mapped to the blue channel. The raw data was preprocessed using Pixinsight, the stars were removed using a tool called "Starnet" I was so delighted with the result of the starless image I decided to post a starless image as well as the image with the RGB stars.
Captured bin 2x2 over 5 nights between March and July 2021 for a total acquisition time of 13.1 hours.
