LRGB Version of B33 Horsehead Nebula with stars
Winter wouldn’t be complete without capturing an object within the glorious constellation of Orion, and fortunately we have a huge legacy archive at Grand Mesa Observatory and this time around I decided to process The Horsehead and Flame Nebula captured using our system 1 from broadband data (LRGB) collected in November 2020.
As I have done this so many times before I decided to process and present both a regular LRGB and starless versions which in my opinion provides a very surrealistic rendering of the nebulous regions full of detail that are otherwise hidden by the many visible stars.
As B33 has been selected as one of the GMO targets for January I am also hoping to add more data in narrowband soon “and when the snow clears”

Less than one hundred light years from the Orion Nebula lies the aptly named Horsehead Nebula, another outcropping of the Orion Molecular Cloud and one of the most recognizable assemblies in the heavens. Whereas the Orion Nebula generates enough light to be visible to the unaided eye, the Horsehead has a far lower surface brightness and presents a challenge to visual observers even with large telescopes. But it’s a delight for astrophotographers and arm chair stargazers.
The Horsehead complex lies just south of the brilliant blue supergiant star Alnitak, the easternmost star in Orion’s Belt and just north of the Orion Nebula. The glowing reddish-pink region in the background is cataloged by astronomers as IC 434. Like the Orion Nebula, IC 434 is an emission nebula. It’s powered by the blazing-hot star Sigma Orionis, just south of Alnitak. Much of the nebula is permeated by tenuous streaks caused by magnetic fields in the region.

Forsaken Nebula is a Hydrogen-alpha emission region that is located just south of the North America and Pelican Nebulae. This dim nebula is often overlooked by astrophotographers who usually favor its brighter neighbors just to its north.
I attempted to use the Foraxx script to derive RGB-colored stars from narrowband data. Not being happy with the result I decided instead to use white stars in this image. The takeaway from this exercise is that there doesn't seem to be a way around shooting RGB stars if RGB stars are to be included in an image.

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.

In this cropped version of the original 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" and the stars were later replaced during Post Processing in Photoshop CC with the more naturally colored stars from the RGB data.
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.

A couple of weeks ago I posted an image of the Soul Nebula without stars as “work in progress” so here is the final result with the more natural star color made possible by inserting stars from the LRGB image into the starless image. In this Hubble Palette version (SHO) the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel and while the colors in this image are not the true colors, the narrowband filters used in the making of this Hubble Palette image reveal much more of the hidden gasses not visible in a broadband image.
Captured over 5 nights in October and November 2020 for a total acquisition time of 23.4 hours.
7000 light-years distant in the constellation of Cassiopeia lies the emission nebula colloquially known as the Soul Nebula. The gasses (mostly hydrogen) that comprise the nebula are being ionized by the stars within the region and as a result, the gases glow, much like a neon sign.The pressures exerted upon the material by the stars nearby are causing the material to become compressed. When enough of the gas becomes highly compacted, it triggers the birth of new stars. In effect, this is a beautiful snapshot of a multimillion-year process of an enormous cloud of dust and gas transforming itself into new stars.

The dim constellation Monoceros, just east of Orion, hosts yet another majestic star factory. The Rosette Nebula, a vast wreath of gas and dust with a cluster of new stars near its center, is not associated with the Orion Molecular cloud but lies further along the Orion Arm of the Milky Way.
The Rosette has an apparent size similar to the Orion Nebula. But at a distance of 5,000 light years, it’s three times farther than the Orion Nebula, which means it’s intrinsically three times larger, spanning a diameter of about 115 light years.

Less than one hundred light years from the Orion Nebula lies the aptly named Horsehead Nebula, another outcropping of the Orion Molecular Cloud and one of the most recognizable assemblies in the heavens. Whereas the Orion Nebula generates enough light to be visible to the unaided eye, the Horsehead has a far lower surface brightness and presents a challenge to visual observers even with large telescopes. But it’s a delight for astrophotographers and arm chair stargazers.
The Horsehead complex lies just south of the brilliant blue supergiant star Alnitak, the easternmost star in Orion’s Belt and just north of the Orion Nebula. The glowing reddish-pink region in the background is cataloged by astronomers as IC 434. Like the Orion Nebula, IC 434 is an emission nebula. It’s powered by the blazing-hot star Sigma Orionis, just south of Alnitak. Much of the nebula is permeated by tenuous streaks caused by magnetic fields in the region.
