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 […]

Melotte 15 – Heart of the Heart Nebula

Melotte 15, a cluster of young super-giant stars in the heart of the heart nebula. The strong stellar winds from this cluster sculpture the gas clouds in their vicinity, creating pillars and cavities. A spectacular array of shapes and colors. This is a narrowband composite using more than 14 hours of data in Ha, OIII, […]

Cygnus Region – Super-Wide-Field Mosaic

This is the main part of the constellation Cygnus, including Deneb and Sadr as main stars, covering a field of about 20 by 20 degrees. This image focusses on the rich H-alpha nebulosity in this region. In contains some of the famous emission nebulae, e.g. the North America Nebula, the Pelican Nebula, the Crescent Nebula, […]

Eastern Veil Nebula – First Light QHY 163m

This is the official first-light for my new QHY 163m cooled CMOS camera. For this, I decided to go for the Eastern Veil Nebula, again. The Veil is definitely one of the most striking supernova remnants. The supernova that created it has exploded 8000 years ago and the remnant has been expanding since then. The […]

IC1396 – Again

Yet another take of the Sh2-131 emission nebula in Cepheus with the embedded star cluster IC1396 and home to the famous Elephant’s Trunk Nebula VDB142. It is a large emissions nebula with stunning inlays of dust clouds absorbing most of the lights. The total size of the complex corresponds to about 10 times the full […]

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 […]
