This is another attempt at the Tadpole Nebula, Sh2-236, 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. This image is a narrowband composite using a total of 6 […]
The Bubble Nebula, NGC 7635, part of a larger HII could, Sharpless 162, in the constellation Cassiopeia with the open cluster 52 in its neighborhood. The “bubble” is produced by the stellar winds from a massive young and hot star, SAO 20575, in its center. The bubble is embedded in a giant molecular cloud that […]
This is my second super wide-field mosaic covering a large part of the constellation Cepheus. It includes many prominent objects: from the M52 Open Cluster, the Bubble Nebula and the Claw nebula on the left to the Elephant’s Trunk and Flying Bat Nebula on the right. As shown in the annotated image below, this region […]
A new three-color narrowband version of the North America and Pelican Complex. 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) show rich and diverse structures filling the […]
Yet another take of 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 […]
The Seagull Nebula, IC 2177 or Sh2-292, in a straight LRGB composite with a total of 16 hours of data. Actually, only the head of the seagull is shown – the wide-spread wings are at and beyond the left edge of the frame. Everything taken with the Astro-Physics RH-305 at the Deep Sky West Observatory. […]
Jones-Emberson 1, also known as PK164+31.1, is a beautiful planetary nebula in the constellation Lynx. Some people also call it the headphone nebula for obvious reasons. It resulted from the collapse of a sun-like star that expelled its outer layers before collapsing to a white dwarf. The picture shows, both, the shells of gas expelled […]
The constellation of Orion is a treasure-trove of deep-sky nebulosity, not only the famous emission nebulae, but also interstellar dust clouds. This is one of them, M78 or NGC2068, an impressive blue reflection nebula about 1500 light-years away and 5 light-years across in the center of the image. The blue nebulosity in the upper part […]
The Helix Nebula again, this time with data from the Astro-Physics Riccardi-Honders-System at Deep Sky West. The pixel scale is around 1 arcsec/pixel, just as for the previous version from the Astro-Physics Starfire Refractor, but the field of view is smaller. At the same time the system is much faster, total integration time was just […]
This is the Helix Nebula, NGC7293, a large planetary nebula located in the constellation Aquarius. It is about 700 light-years away, spanning about 2.5 light-years. The image uses RGB data, with additional Ha data to enhance the luminance channel, taken with the Astro-Physics 175 Starfire Refractor from the Deep Sky West Observatory. Exposure: H […]
Sharpless2-188, a difficult target already for narrowband imaging. This version, however, is RGB with Ha mixed into the luminance channel. This object is an unconventional planetary nebula located in the constellation Cassiopeia. The expanding gas from the planetary nebula is colliding with ambient gas in the interstellar medium. The nebula is brighter to the southeast […]
