Color NB

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.

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 […]

Rosette Nebula

The Rosette Nebula, a stunning emission nebula at the edge of a large molecular cloud in Monoceros, some 5000 light years away. Its flowery appearance is sculpted by the winds and radiation from its central cluster of hot young stars. This is a narrowband composite from (16,16,20) x 1800 sec exposures in Ha, OIII, and […]

Cygnus Loop in Bicolor

The complete Cygnus Loop or Veil Complex in a bicolor narrowband rendering. Recently, I posted a version of the same object taken during my summer vacation in the Mediterranean. I liked it, but was not perfectly happy with the raw data and the processing. So, back home I decided to do it again from scratch, […]

Great Cygnus Wall

The southern part of the North America Nebula, NGC7000, with a dramatic cloudy ridge also known as the Cygnus Wall – the most active star forming regions in the nebula. This image is composed of Ha, OIII, and SII frames with a total of 22 hours of exposure time. Exposure: HOS, (18,10,16) x 1800sec Date: […]

Sh2-86

Sharpless 86 (Sh2-86) is a rich and beautiful emission nebula surrounding the open star cluster NGC 6823 plus small reflection nebula NGC 6820 in Vulpecula. The star cluster including 50 to 100 stars was discovered by William Herschel in 1785 and is about 6000 light years away. The remarkable pillar like features that are pointing […]

Sh2-119

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 […]

IC1396 – Emission Nebula in Cepheus – Bicolor

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 […]

North America and Pelican Complex

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) […]

Cygnus Loop – Wide Field II

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 […]

Cygnus Loop – Wide Field

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 […]

NGC6888 – Crescent Nebula

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.
