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. Exposure: HOS, […]

M42 – Orion Nebula in Color

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: […]

EGB6 – An Ancient Planetary Nebula

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 […]

Heart Nebula – IC1805

The Heart Nebula IC1805 – it is kind of obvious why it got its name. The Heart Nebula is an emission nebula and star forming region of almost 200 light-years across, located within the Perseus Arm of our Milky Way galaxy, about 7500 light-years away in the northern constellation Cassiopeia. This is a complete narrowband […]

Pacman Nebula – NGC281

The Pacman Nebula (NGC281) is an active star forming region. Prominent features include a small open cluster of stars, a diffuse red-glowing emission nebula, large lanes of obscuring gas and dust, and dense knots of dust and gas in which stars may still be forming. The open cluster of stars IC1590 visible around the center […]

Elephant’s Trunk Nebula – IC1396

The Elephant’s Trunk Nebula is an elongated dark globule within the emission nebula IC 1396 in the constellation of Cepheus. Located at a distance of 2,450 light-years, the globule is a condensation of dense gas that is barely surviving the strong ionizing radiation from a nearby massive star. The globule is being compressed by the […]

Heart Nebula – IC1805

The Heart Nebula IC1805 – it is kind of obvious why it got its name. The Heart Nebula is an emission nebula and star forming region of almost 200 light-years across, located within the Perseus Arm of our Milky Way galaxy, about 7500 light-years away in the northern constellation Cassiopeia. This is a two-color narrowband […]

Bubble, Claw and More

A quite busy scenery… including the Bubble Nebula NGC7635 together with the open cluster M52 in the upper right, the Lobster Claw Nebula Sh2-157 in the lower left, and NGC7538 in the lower right. This is a two-panel mosaic of Ha, OIII and SII narrowband exposures with a total of 48 hours (!) worth of […]

Western Veil Nebula – NGC6960

Here is the western part of the Veil Nebula, also known as Witches Broom, again as a bi-color image composed of Ha and OIII data taken from my backyard. The Veil is one of the largest and most spectacular supernova remnants. The supernova that created it has exploded 8000 years ago and the remnant has […]

Eastern Veil Nebula – NGC6992, NGC6995

It has been a while since the last few hours of clear skies from my backyard, but now I had another chance. I decided to go for a bi-color image of the Eastern Veil Nebula using Ha and OIII data. The Veil is one of the largest and most spectacular supernova remnants. The supernova that […]
