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 moon. This is a […]

The Sadr region, IC 1318, is the busy neighborhood round the mag 2.2 star Sadr or gamma Cygni. It is a large expanse of nebulosity with dominant Ha emission nebulae and various dark nebulae. The Crescent Nebula (in the lower left cover of the image) is embedded into the region. This is one of my […]
The Sadr region, IC 1318, is the busy neighborhood round the mag 2.2 star Sadr or gamma Cygni. It is a large expanse of nebulosity with dominant Ha emission nebulae and various dark nebulae. The Crescent Nebula (in the lower left corner of the image) is embedded into the region. This is a simple Ha […]
Now the full three-color narrowband version of the North America and Pelican Complex, following my earlier Ha monochrome version. 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) […]
This is the second target for my new wide-field setup, the North America and Pelican Complex. Both 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 a rich and […]
Now the three-color version of the Cygnus Loop in Ha, OIII and SII using 24 x 300 sec exposures for each channel, i.e. a total of 6 hours. Taken with the ATIK 460EXm camera in combination with my Asahi/Pentax Takumar 135mm f2.5 photo lens. Exposure: HOS, (24,24,24) x 300sec Date: 2016-7-17…2016-7-18 Setup: Takumar 135mm f2.5 […]
This is the first-light image with my new wide-field travel setup. I decided to try the ATIK 460EXm camera in combination with some old M42 photo lens, in this case with the Asahi/Pentax Super-Multi-Coated Takumar 135mm f2.5, a wonderful super-solid 6-element tele-lens from 1972 (my age). This combination gives a field of view of more […]
The Crescent Nebula, NGC 6888, in a wide-field setting with lots of surrounding nebulosity. This is a pure narrow-band composite based on (18,16,15) frames for Ha, OIII, and SII with 1800sec each, taken at the Deep Sky West Observatory. The different versions below represent different color mappings, otherwise the processing is pretty basic. Exposure: HOS, […]
Following the plain H version, here the false-color HSO image of the Orion Nebula, M42. I went for a unconventional color scheme, which highlights the structure of the nebula outside of its main part… lots of dynamics. Exposure: H 16x60sec + 14x300sec + 8x900sec, S 11 x 1800sec, O 18 x 1800sec Date: 2016-1-17 Setup: […]
Something simple for a change… the Orion Nebula, M42, and its neighbourhood in H-alpha light. This mono image results from an HDRComposition of stacked frames with three different exposures to cover the large dynamic range of this target. Exposure: H, 16x60sec + 14x300sec + 8x900sec Date: 2016-1-17 Setup: Takahashi FSQ106 EDXIII with QSI 683WSG-8 Site: […]
This in an incredibly faint object – EGB 6 – discovered by Ellis, Grayson, and Bond in 1984 in a visual search through prints from the Palomar Sky Survey. Here is a link to their original paper. EGB 6 is an old and hence large planetary nebula with extremely low surface brightness. The image is […]
