The garlic nebula | CTB1/Abell 85 was discovered in 1955 by George Abell on the Palomar survey plates, thinking it was a planetary nebula based on its shape. Later scientists found out that it is a supernova remnant based on its radio signal. Thus, CTB1 is probably the proper designation for this object, even though Abell was actually the discoverer. HOO Image with RGB stars! - Realizado com Pictrs.comThe eye of the universe | This object is called the Wolf-Rayet-134 Ring or Bubble Nebula. But for me it looks like an eye with a dolphin as eyebrow. At least if one emphasises the OIII line as I did. This is a so called HOO image, taken with a full frame cooled astro mono cam and a Ha-Narrowband-Filter and a OIII-Narrowband-Filter. The stars were taken with RGB-Filters. The OIII-line is represented by the blue colours and the Ha-line by the redish ones. Wolf-Rayet 134 is the brightest white star in the center of the eye. Wolf-Rayet-Stars are extremely hot, bright, massive stars, and one of the rarest classes of stars known out there. There are not even 200 of these stars known in the Milkyway which hosts more than 1 Billion of stars. Some of these Wolf-Rayet-Stars produce spectacular nebulae thanks to their strong stellar winds, intense ultraviolet emissions, and clouds of gasses that they shed in earlier stages of their relatively brief lives. - Realizado com Pictrs.comThe Egg of the Dragon | lights-and-darks - Realizado com Pictrs.comEta Carina | lights-and-darks - Realizado com Pictrs.comThe fighting dragons of Ara and the dragons egg | The fighting dragons of Ara and the dragons egg ...This image shows the Fighting dragons in the constellation of Ara (NGC 6188) and the dragon`s egg (NGC 6164). It`s an emission nebula located about 4,000 light years away from earth.Due to its hydrogen-rich clouds, NGC 6188 is a region of active star formation, and its structure is shaped by the powerful stellar winds of the young and massive stars within.The glowing bipolar planetary nebula, NGC 6164, is visible at the bottom of the frame, which many refer to as the "dragon's egg".Took it in Namibia and it`s an RGBHOO Image. - Realizado com Pictrs.comThe cosmic jellyfish | The cosmic Jellyfish ...from wikipedia:The Jellyfish Nebula aka Medusa Nebula (IC 443 or Sharpless 248 (Sh2-248)) is a galactic supernova remnant (SNR) in the constellation Gemini. On the plane of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth. IC 443 may be the remains of a supernova that occurred 3,000 - 30,000 years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.SHO version with rgb stars shot on a full frame mono astrocam. Roughly 34hours of total integration! - Realizado com Pictrs.comThe cosmic Lion | The Cosmic LionThe Lion Nebula (Sh2-132) is a rich Ha region and emission nebula. It's rather faint and lies at the Borderline between cepheus and lacerta roughly 10.000 lightyears away from earth.This one ins from my remote observatory in Austria. HSHO version with RGB stars! Roughly 30h of integration. - Realizado com Pictrs.comThe giant squid | SH2-129 is a relatively faint emission nebula in Cepheus, a neighbor of the larger and more often imaged IC 1396. Sometimes referred to as the "Flying Bat" nebula, this region is characterized by Ha emission as well as a small, mixed emission and reflection nebula (vdB 140). What is most remarkable about this region is a recent discovery made in 2011 by Nicolas Outters, called the "Squid Nebula" due to its shape, but more officially called Ou4. This region is characterized by a very faint OIII emission that has a bipolar shape reminscent of a planetary nebula, seen as the teal-colored region in the image looking like a squid, hence the name. Although it was originally thought to perhaps represent a planetary nebula derived from an unknown, dying star, more recent evidence suggests that Ou4 is located within SH2-129 itself and is a bipolar outflow emitting in the OIII spectrum, moving at the same rate as SH2-129, and possibly emanating from a triple star system located in the center of Ou4 (HR8119, visible above as the bright star in the center of the Squid). Shot on an 11" astrograph and a full frame mono astrocam nearly 19h of OIII, 2:45h Ha 30min per rgb filter - Realizado com Pictrs.comThe wizard of the universe | The Wizard Nebula is a collection of interstellar gas surrounding the open star cluster, NGC 7380. It lies approximately 7200 light-years away from Earth in the constellation Cepheus and is located in the Perseus Arm of the Milky Way. See my second image where it is in the Milky Way! SHO image (the so called Hubble Palette, because the famous telescope takes pictures this way). So Sulphur is put into the Red Channel, Hydrogen into the Green Channel and Oxygen into the Blue Channel. The Channels where shot with Narrowband Filters and a Mono-Astrocam. The stars are shot with RGB-Filters and the same Mono-Astrocam. Total Integration Time 10hours 40 minutes with a fast f2.2 telescope at 620mm focal length. - Realizado com Pictrs.comThe Cosmic Bat | LDN43 - Realizado com Pictrs.comThe Large Magellanic Cloud | The Large Magellanic Cloud (LMC) is a satellite galaxy of the Milky Way at a distance of around 163,000 light-years. It is the fourth-largest galaxy in the Local Group, after the Andromeda Galaxy (M31), the Milky Way, and the Triangulum Galaxy (M33) at roughly one-hundredth the mass of the Milky Way. RGBHOO image shot in Namibia. - Realizado com Pictrs.comLagoon_rgb_PS_1_1_20231104 | lights-and-darks - Realizado com Pictrs.comEagle flying around the pillars of creation | M16, IC 4703 - Realizado com Pictrs.comThe Orion Nebula | M42, the Orion nebula, is a well known target. I pictured it from the darkest sky available completely without filters to get the natural colours and to reveal the faint dust clouds around it. The entirety of the Orion Nebula extends across a 1° region of the sky, and includes neutral clouds of gas and dust, associations of stars, ionized volumes of gas, and reflection nebulae. I also did an HDR image to avoid burning out the core, which is so much brighter than the rest. From Wikipedia: The Nebula is part of a much larger nebula that is known as the Orion molecular cloud complex. The Orion molecular cloud complex extends throughout the constellation of Orion and includes Barnard's Loop, the Horsehead Nebula, M43, M78, and the Flame Nebula. Stars are forming throughout the entire Cloud Complex, but most of the young stars are concentrated in dense clusters like the one illuminating the Orion Nebula. Shot from Namibia - Realizado com Pictrs.comPortrait of the hunter | 4 panel mosaic of the Orion Region featuring a lot of prominent deepsky objects, like the Orion Nebula (M42), the Horsehead (NGC 2023) and Flame Nebula (NGC 2024), Casper the friendly Ghost Nebula (M78), Barnard's Loop (SH2-276), the Witchhead nebula (IC 2118) and many more. 135mm focal length with astromodified full frame cam, no filter Shot over 8 nights in Las Tricias (la Palma) but I had to remove many hours of exposure due to heavy Calima (sand in the air) so its roughly 4 hours of Integration for each panel. - Realizado com Pictrs.comOmega Centauri | lights-and-darks - Realizado com Pictrs.comThe rose of the universe | Two panel mosaic of the Rosette Nebula (NGC 2244). From Wikipedia: "The Rosette Nebula (also known as Caldwell 49) is an HII region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter." - Realizado com Pictrs.comGhost Rider | SH2-63 - Realizado com Pictrs.comSouthern Jewels | Corona Australis - Realizado com Pictrs.comStatue of Liberty | lights-and-darks - Realizado com Pictrs.comTarantula | The Tarantula Nebula (also known as 30 Doradus or NGC 2070) is a large emission nebula in the Large Magellanic Cloud (LMC), forming its south-east corner (from Earth's perspective). For those who don`t know ... the LMC is a not so well known neighbouring galaxy to our milkyway. That means, this nebula is not in the milkyway. It`s one of the biggest and most active starburst region known in the Local Group of galaxies. Most of you may know the famous Orion Nebula (M42) which is one of the closest starburst regions to earth. To give you a hint how large the Tarantula Nebula is: Would it be at the same distance to earth as the Orion Nebula it would span across half of the night sky and i would never be dark if it shows up. The LMC is only visible from the Southern hemisphere. Shot from Kiripotib in Namibia! - Realizado com Pictrs.comThe Trifid Nebula | The Trifid Nebula (M20) is part of the so called Saggitarius Triplet and sits in the middle of the center of our galaxy. It is an unusual combination of an open cluster of stars, an emission nebula (the reddish-pink part), a reflection nebula (the blue portion), and a dark nebula (the apparent 'gaps' in the former that cause the trifurcated appearance, also designated Barnard 85 from Wikipedia). This is the natural colour palette. Normally I am of the opinion that we amateur astro photographers are more into doing art than science - so the colour is a little bit of artistic freedom. espescially when doing narrow band imaging. However this object is really beautiful and I had enough high quality broadband data so I decided to spectro photometric colour calibrate it to get the coulors as natural as possible. Shot only with an IR-UV blocking filter from Kiripotib in Namibia. - Realizado com Pictrs.comThe Bluehorsehead Nebula | The Bluehorsehead Nebula (IC 4592) is a reflection nebula in the scorpius constellation. It is lit by Nu Scorpi, the Star also representing the eye of the horse. Shot taken in Namibia with a cooled mono astrocam with rgb Filters. - Realizado com Pictrs.com
