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 – […]

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 – 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. […]

Sharpless 171

A plain H-alpha image of the central region of Sharpless 171 (Sh2-171). This busy region is surrounded by another ring of gas, not visible in this frame. Composed of a total of 4.5 hours of 10 min exposures from my backyard. A first test of the 0.79 Reducer from TS… stars are looking good already. […]

Bubble Nebula & M52

Exposure: H, 30 x 600sec Date: 2016-12-03 Setup: APM 107/700 Triplet APO with ATIK 460 EXm Site: Langen, Hessen, Germany

Heart of the Heart Nebula

The central section of the Heart Nebula (IC1805) with the open cluster Melotte 15. The stellar wind and radiation from this cluster of massive host stars, about 1.5 million years young, has sculputured the emission nebula and dark dust clouds into a dramatic scenery. One more quick mono Ha image of a well known object […]

Flaming Star Nebula

The Flaming Star Nebula in a simple Ha narrowband image. Composed of a total of 4 hours of data taken from my balcony in the light-polluted Frankfurt area – Bortle class 7 (red zone). Exposure: H, 24 x 600sec Date: 2016-12-04 Setup: APM 107/700 Triplet APO with ATIK 460 EXm Site: Langen, Hessen, Germany

Elephant’s Trunk Nebula

This is the official first-light image with my new APM 107/700 Triplet APO! It works beautifully with the Hotech SCA Field Flattener and the ATIK 460EXm and produces a nice flat field – much better than my previous setup. This combo will be my high-resolution combo for quite some time. As you will have guessed […]

Sh2-119 – Mono

This is Sharpless 119 (Sh2-119), a nice an often forgotten emission nebula sitting right next to the North America Nebula – somewhere in the Pacific Ocean. Probably, this is why are there not many images of it. In addition to the dominant H-alpha emission there are some prominent dark dust lanes. In the center of […]

Sh2-129 – Potato Nebula – Mono

Some people call it Flying Bat Nebula, but I think Potato Nebula is the more fitting name for Sharpless 129 (Sh2-129). The bright star in the upper-right is Alderamin and in the upper-left quadrant you will find a nice compact planetary nebula. This target deserves a little more exposure time to bring out more of […]
