Below is an Award Winner (2017 Astrobin Best Pick) processed color image showing a Hubble Palette version of a portion of Sharpless 2-132 (Lion Nebula) that was created by processing 54 stacked, calibrated, and aligned H-Alpha, Oxygen, Sulphur, and Nitrogen narrowband sub images.

Noted Astrophotographer Sara Wager had this to say about the Lion Nebula…

”Sharpless 2-232 is a very faint emission type nebula on the Cepheus/Lacerta border. It lies at a degree southeast of Epsilon CEP, and has a size of about 40 arc minutes.

It is estimated to be about 10,000 to 12,000 light years away… but this is no more than an estimite. It’s a well studied region as well, with lots going on.”

This selection is from the Sharpless catalog which offers listings of famous objects like the Orion Nebula as well as faint objects that were difficult objects for amateurs in the film era. With the advent of digital photography, these faint nebulae have become more accessible. I have found the catalog to be a promising resource for astrophotography target selection.

More can be found on the web about Stewart Sharpless and his catalog at “The Best of Sharpless Catalog.” Accordingly to that resource…

“Many famous objects are imaged by amateur astronomers who are unaware that they are part of the Sharpless (SH2) catalog.  The great Orion nebula, also known as Sh2-281, and the commonly imaged Flame nebula, known as SH2-277, are some of the December favorites.  Six months later in the month of June, SH2-25, which is also known as The Lagoon nebula and the North American Nebula listed in the catalog as SH2-117, are in the sky. 

Some of the objects that Sharpless includes are not HII nebulae at all; instead they are reflected star light off a galactic dust cloud above and below our own galaxy.  This is known as Integrated Flux Nebulae which Steve Mandel cataloged in his Unexplored Nebulae Project.  There are a few Sharpless catalog numbers that fall into this, the largest labeled Sh2-178 near the North Star Polaris.”

The sub images were taken at the Astro La Vista Observatory in Prescott, Arizona with an APM 152MM 1200MM focal length ED APO refractor mounted on an Astro-Physics 1100GTO mount with encoders. The imaging camera was a QSI 690wsg with a Lodestar guider.

Frames were taken in the Fall of 2017 as follows:

Astrodon True-Balance 3NM H-Alpha 12×1800” (6 hours) bin 2×2

Astrodon True-Balance 3NM Oxygen 18×1800” (9 hours) bin 2×2

Astrodon True-Balance 3NM Sulphur 12×1800” (6 hours) bin 2×2

Astrodon True-Balance 3NM Nitrogen 12-1800” (6 hours) bin 2×2

Included in the download are a cropped and rotated version of the files, as well as unmodified versions for your processing convenience.

Below is a processed color image showing an interior closeup of a portion of the Flaming Star Nebula that was created by processing 310 stacked, calibrated, and aligned H-Alpha, Oxygen and RGB sub images. It shows the distinctive blue color of a reflection nebula near the star AE Aurigae and the pink color of ionized gas elsewhere in the image.

According to the “Annals of the Deep Sky” by Jeff Kanipe and Dennis Webb, one of the discoverers, Max Wolf, set the stage for the naming of the nebula. “In a paper he described AE Aurigae as ‘a burning body from which several enormous curved flames seem to break out like gigantic prominences.’ He urged spectroscopists to observe this ‘flaming star . . ., which seems physically connected with the nebulous matter.'”

An H-Alpha image is especially detailed and stunning when taken with long exposures and an ultra narrowband filter.

I have to say that this has to be one of the finest sets of sub images that I have ever taken. The sub images were taken at the Astro La Vista Observatory in Prescott,AZ. with an APM 152mm 1200mm focal length ED APO refractor mounted on an Astro Physics 1100GTO mount with encoders. The imaging camera was a QSI 690wsg with a Lodestar guider. The imaging field of view was only .366 degrees and the pixel scale was .626 arc seconds per pixel.

Frames were taken in October and November of 2020 as follows:

Astrodon Gen2E Red: 90×60″ (1 hr. 30″) bin 1×1

Astrodon Gen 2E Green: 90×60″ (1 hr. 30″) bin 1×1

Astrodon Gen 2E Blue: 90×60″ (1 hr. 30″) bin 1×1

Astrodon Tru-Balance 3nm OIII: (20×1800″) bin 1×1

Astrodon Tru-Balance 3nm Ha: (20×1800″) bin 1×1

As you might be aware, Astrodon filters have been the gold standard for astro imaging. The ultra narrow band filters are expensive and often not readily available.

It takes a very robust imaging setup to achieve the precision necessary to get 1800 second subs with a 6 inch 1200mm refractor. I hope you can utilize these exquisite images to produce your own work of art with attribution.
