The Heart Nebula (IC1805, Sh2-190) is an emission nebula located in the constellation Cassiopeia. It its about 7500 light years from earth in the Perseus Arm of our Milky Way galaxy. It has a diameter of about 165 light years. This image shows the hear of the Heart Nebula, the […]

After the first-light version of Pickering’s Triangle we collected a few hours more data of this fascinating part of the Cygnus Loop. This combined set of 15 hours of H-alpha and OIII narrowband data allows to bring out all the intricate structure in this supernova remnant. To emphasize the nebulosity […]
The Pacman Nebula (NGC281, IC11, Sh2-184) is a nice combination of an emission nebula and some dust clouds. It is located in the constellation Cassiopeia at a distance of about 9000 light years. The false-color images below are composed of narrowband exposure using Ha, OIII, and SII filters. The way […]
Among the more mysterious deep-sky objects are dark nebulae – clouds of interstellar dust that do not emit light themselves, but absorb the light from background stars. Hidden the denser regions of these dust clouds new stars are formed, new stars from the ashes of previous generations. Observing them requires […]
The Andromeda Galaxy, M31, a truly magnificent sight. It is the sister of our own galaxy and the closest major galaxy with a distance of only 2.5 million light years. Our Milky Way, the Andromeda Galaxy, and the Triangulum Galaxy, M33, are members of the Local Group, which also hosts […]
The Crescent Nebula, NGC6888, is one of the prominent emission nebulae in Cygnus, about 5000 light years away from Earth. It is associated with the Wolf-Rayet star WR136. When this star turned into a red giant about 100,000 years ago, it expelled its outer layers of gas, which slowly expanded […]
The Elephant’s Trunk is one these mysterious combinations of dark dust clouds embedded into bright emission nebulae. The elephant’s trunk itself is the dark horizontal column left of the center in the image below. It is embedded into a much larger emission nebula IC1396 in the constellation Cepheus at a […]
This is the last in our series of “first light” images taken at the TURMX observatory. All of the data for these first light images was collected in the first two or three weeks of remote operation. The object for this image is the so-called Cygnus Wall, a part of […]
Pickering’s Triangle is named after Professor Edward Charles Pickering, director of the Harvard College Observatory. It should better be called Fleming’s Triangle, because it was discovered by Williamina Fleming as part of her work on evaluating photographic plates at Pickering’s observatory. It is a part of the Cygnus Loop or […]
The Iris Nebula is one of the most famous reflection nebulae. It is located about 1300 light years away in the constellation Cepheus. The bright reflection nebula showing the characteristic blue hue is actually a part of a larger dark dust cloud. It appears bright because light from a star […]
The Cygnus Loop is one of the iconic emission nebulae in the constellation Cygnus. This region of sky is very rich in stunning emission nebulae of different origin. One of these gas clouds is the Cygnus Loop – a large structure whose different parts go under a number of names: […]
This is one of the grand galaxies of the Local Group, a sister galaxy of our own Milky Way Galaxy. This is the Triangulum Galaxy, or Messier 33, in the constellation Triangulum. It is 2.7 million light years from Earth, has a diameter of 60,000 light years, and hosts about […]
This is one of the first images taken with our TURMX remote setup at the E-EyE observatory. The target ist a classic, the globular cluster M13 in the constellation Hercules, one of the most magnificent clusters in the northern sky and also known as the Great Globular Cluster in Hercules. […]
