Orion Region – Super-Wide-Field

I was planning to get a wide-field shot of Orion with Barnard’s Loop for quite some time. Somehow, the weather never cooperated and even now the conditions were far from good… Anyways, I did process this first batch of data for a 3 x 4 mosaic of Barnard’s Loop, just to get an idea. I […]

Tadpole Nebula – IC410

This is another attempt at the Tadpole Nebula, Sh2-236, in a bi-color HO narrowband image. You can easily find the two tadpoles that give rise to the name of this nebula. It belongs to one big emission complex together with the Flaming Star Nebula. This image is a narrowband composite using a total of 6 […]

Bubble Nebula – NGC7635

The Bubble Nebula, NGC 7635, part of a larger HII could, Sharpless 162, in the constellation Cassiopeia with the open cluster 52 in its neighborhood. The “bubble” is produced by the stellar winds from a massive young and hot star, SAO 20575, in its center. The bubble is embedded in a giant molecular cloud that […]

Cepheus Region – Super-Wide-Field

This is my second super wide-field mosaic covering a large part of the constellation Cepheus. It includes many prominent objects: from the M52 Open Cluster, the Bubble Nebula and the Claw nebula on the left to the Elephant’s Trunk and Flying Bat Nebula on the right. As shown in the annotated image below, this region […]

Andromeda Galaxy – M31

The Andromeda Galaxy M31 a truly magnificent sight. It is the sister of our own galaxy and the closest major galaxy. Our Milky Way, the Andromeda Galaxy, the Triangulum Galaxy M33 are members of the Local Group. M31 contains about 1 trillion stars, twice as many as our home galaxy. It’s not only one of […]

North America and Pelican Complex – Again

A new three-color narrowband version of the North America and Pelican Complex. Both nebulae belong to the same interstellar cloud of ionized hydrogen gas, but they are separated by a ragged lane of interstellar dust that absorbs their light. The North America (NGC7000) and the Pelican Nebula (IC5070) show rich and diverse structures filling the […]

Elephant’s Trunk Wide-Field

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 […]

Markarians Chain

On end of Markarians Chain with M84, M86 and NGC4438 (The Eyes) plus lot of smaller galaxies. Straight LRGB with data from the Astro-Physics RH-305 at Deep Sky West Observatory. Exposure: LRGB (24,24,24,24) x 600sec Date: 2018-04-10…2018-05-16 Setup: Astro-Physics RH-305 with FLI ML8300 Site: Deep Sky West Observatory, NM, USA

NGC3718

This is NGC 3718, a twisted spiral galaxy with dust lanes obscuring its yellowish central regions. Only 150000 light-years to the left is another large spiral galaxy, NGC 3729. The two are likely interacting gravitationally, accounting for the peculiar appearance of NGC 3718. While this galaxy pair lies about 52 million light-years away, the Hickson […]

NGC6888 – Crescent Nebula

The Crescent Nebula, NGC 6888, based on H and O narrowband data provided by Adam Jaffe via The Astro Imaging Channel. Exposure: HO (18,18) x 1800sec Date: 2018-07-16…2016-07-30 Data by Adam Jaffe The Astro Imaging Channel

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 […]
