IC2177 – Seagull Nebula

The Seagull Nebula, IC 2177 or Sh2-292, in a straight LRGB composite with a total of 16 hours of data. Actually, only the head of the seagull is shown – the wide-spread wings are at and beyond the left edge of the frame. Everything taken with the Astro-Physics RH-305 at the Deep Sky West Observatory.

Jones-Emberson 1 in RGB and HO

Jones-Emberson 1, also known as PK164+31.1, is a beautiful planetary nebula in the constellation Lynx. Some people also call it the headphone nebula for obvious reasons. It resulted from the collapse of a sun-like star that expelled its outer layers before collapsing to a white dwarf. The picture shows, both, the shells of gas expelled […]

Triangulum Galaxy – M33

The Triangulum Galaxy (M33, NGC598) the third largest member of the local group, with its larger sisters the Andromeda Galaxy and our Milky Way. It consists of 40 billion stars, really small compared to the 400 billion of the Milky Way and the 1 trillion of the Andromeda Galaxy. This image is an LRGB composite […]

M78 and McNeil’s Nebula

The constellation of Orion is a treasure-trove of deep-sky nebulosity, not only the famous emission nebulae, but also interstellar dust clouds. This is one of them, M78 or NGC2068, an impressive blue reflection nebula about 1500 light-years away and 5 light-years across in the center of the image. The blue nebulosity in the upper part […]

Helix Nebula in RGB – Different Data

The Helix Nebula again, this time with data from the Astro-Physics Riccardi-Honders-System at Deep Sky West. The pixel scale is around 1 arcsec/pixel, just as for the previous version from the Astro-Physics Starfire Refractor, but the field of view is smaller. At the same time the system is much faster, total integration time was just […]

Helix Nebula in RGB

This is the Helix Nebula, NGC7293, a large planetary nebula located in the constellation Aquarius. It is about 700 light-years away, spanning about 2.5 light-years. The image uses RGB data, with additional Ha data to enhance the luminance channel, taken with the Astro-Physics 175 Starfire Refractor from the Deep Sky West Observatory.   Exposure: H […]

Sh2-188 in RGB

Sharpless2-188, a difficult target already for narrowband imaging. This version, however, is RGB with Ha mixed into the luminance channel. This object is an unconventional planetary nebula located in the constellation Cassiopeia. The expanding gas from the planetary nebula is colliding with ambient gas in the interstellar medium. The nebula is brighter to the southeast […]

Iris Nebula – AP175 Refractor

This is the Iris Nebula, NGC7023, as seen with the Astro-Physics 175 Starfire Refractor from the Deep Sky West Observatory.   Exposure: LRGB (21,27,23,10) x 900sec Date: 2017-07-17…2017-09-21 Setup: Astro-Physics 175 Starfire with FLI PL16070 Site: Deep Sky West Observatory, NM, USA

Cocoon Nebula

The Cocoon Nebula, IC5146, seen with the RH-305 setup at the Deep Sky West Observatory. I was hoping to get a more prominent appearance of the dark lane extending from the Nebula itself… will have to reprocess this image to get out more. Still, the colors are beautiful. Exposure: LRGB, (63,22,13,18) x 600sec Date: 2017-05-05…2017-09-16 […]

Pelican Nebula – NB vs. RGB

Two different perspectives on the head of the Pelican Nebula: false-color narrow band (above) and real color RGB (below). Both taken with the same setup, the new Astro-Physics 175 mm f/8 Starfire EDF at the Deep Sky West Observatory. Processing was very straight forward, no tricks necessary.   Exposure: HOS (13,5,10) x 1800sec LRGB (14,15,14,9) […]

M20 – Trifid Nebula

This is the Trifid Nebula, M20, with the open cluster M21, my first test target from the new Astro-Physics 175 mm f/8 Starfire EDF at the Deep Sky West Observatory. Processing was very straight forward, no tricks necessary. Exposure: LRGB, (22,8,9,10) x 600sec Date: 2017-06-14…2017-06-30 Setup: Astro-Physics 175 Starfire with FLI PL16070 Site: Deep Sky […]

Supernova SN2017eaw in NGC6946

My first shot of the Fireworks Galaxy, NGC6946, with the Supernova SN2017eaw (marked) that was discovered 13 days earlier, on May 14th. A list of photometric and photographic observation of the supernova can be found here. Data taken at the Sternenwelt Vogelsberg. My equipment was not running too well, guiding and auto-focussing were bumpy. I […]
