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.

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 […]

Cygnus Region – Wide-Field Mosaic

This is the central part of the constellation Cygnus, including Deneb and Sadr as main stars, covering a field of about 13 by 10 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, and the Crescent […]

Flaming Star Region – Wide Field

The Flaming Star Region, including the Flaming Star Nebula (Sh2-229, IC405), the Tadpole Nebula (Sh2-236, IC410), the Spider Nebula (Sh2-234, IC417), the Fly Nebula (Sh2-237), the Starfish Cluster (M38), and some more stuff. This is a wide field monochrome image using 3 hours of Ha data taken from my backyard in the light-polluted Frankfurt area […]

Cone Nebula & Christmas Tree – Wide Field

This is a very wide field monochrome image of the region around the Cone Nebula and the Christmas Tree Cluster. They are sitting in the middle of a much larger emission nebula with lots of structures. Composed of more than 6 hours of Ha data taken from my backyard in the light-polluted Frankfurt area – […]

Barnard 22 and Little Flame

Dark nebula Barnard 22 with embedded reflection nebula IC2087. An LRGB composite using 30+20+20+20 individual frames with 900 sec exposure time. Data taken at the Deep Sky West Observatory. Exposure: LRGB, (30,20,20,20) x 900sec Date: 2017-01-22…28 Setup: Takahashi FSQ106 EDXIII with QSI 683WSG-8 Site: Deep Sky West Observatory, NM, USA

IC447

Exposure: LRGB, (19,16,16,16) x 900sec Date: 2016-12-10…2017-01-18 Setup: Takahashi FSQ106 EDXIII with QSI 683WSG-8 Site: Deep Sky West Observatory, NM, USA

Wizard Nebula – Sh2-142

The Wizard Nebula, Sh2-142, in a plain H-alpha image. Composed of a total of 7.5 hours of 10 min exposures from my backyard. Exposure: H, 45 x 600sec Date: 2016-12-29… 2017-01-07 Setup: APM 107/700 Triplet, 0.79 Reducer, ATIK 460 EXm Site: Langen, Hessen, Germany

Tadpole Nebula – Sh2-236

The Tadpole Nebula, Sh2-236, now 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. Composed from over 9 hours of 10 min exposures with the Baader Ha and OIII […]

Tadpole Nebula – Sh2-236 – Mono

The Tadpole Nebula, Sh2-236, in an plain H-alpha image. You can easily find the two tadpoles that give rise to the name. It belongs one one big emission complex together with the Flaming Star Nebula. Composed of a total of over 5 hours of 10 min exposures from my backyard. See also the bicolor version. […]
