This image presented some interesting processing challenges, but I'm pretty happy with how it came out. Big shout-out to Russ Croman and his Photoshop plugins, which were invaluable to getting this one done!

Image Description and Details : The main goal of this project was to capture the exceptional, extremely colorful, gigantic region enclosing the emission, reflection and dark nebulae around stars named Rho Ophiuchi, Antares and Alniyat, as well as neighboring objects (M4 globular cluster and others). This region is commonly referred as Rho Ophiuchi Molecular Clouds Complex in the astronomical literature. The nebulae have very intensive colors depending on the ionized and molecular gas composition (yellow-orange and reddish colors) or due to the visible light reflexion (blue colored nebulae). Dark nebulae does not transmit much light due to the presence of interstellar dust. This region covers a gigantic region on the night sky compared to many other deep space objects and is located on the border of the Scorpius and Ophiuchus constellations. A total length of 8 Full Moons could be placed side-by-side on the wider, horizontal side of this mosaic. The high dynamic range of colors and contrast in each panel, as well as the size of each file (few gigabytes due to the high resolution) resulted in complex and unusually long computer processing procedures. This 4-panel mosaic is produced by combining the integrated data collected using two different telescopes (Askar FRA400 and William Optics FLT-91) in the last two years. The same astronomic camera (ZWO ASI294 MM Pro with thermoelectric cooling) and same dichroic broad-range filters (Chroma RGB set) were used. Total integration time is on average 4.5 hours per panel. Imaging sessions required a total of 7 car trips to two different locations (Rudine near Skopje and Radibush near Kriva Palanka) spanning driving around 800 km. Difference in the telescopes focal length (280 and 432 mm) and changes in the atmospheric conditions between different nights impose real processing challenge.

Image Description and Details : This is one of the hardest deep space objects I have ever processed. I was well past diminishing returns in the amount of integration time I captured for my poor bortle 8 skies. I started capturing this April of this year; four months ago. It was even more challenging than the squid nebula; Ou4. While Jacoby 1 has only a designation name, I decided to call it the coffee stain planetary nebula for obvious reasons. Jacoby 1 lies within the Bootes constellation. It was discovered in 1995 by George Jacoby. It's amazing given how faint it is that he was able to discover it in the first place.

It was discovered by the German-French team of Marcel Drechsler and Xavier Strottner in 2020 and has the catalogue designation StDr 16 / PNG 039.1-04.5. This photo, taken in collaboration with Sven Eklund from Sweden and processed by Marcel Drechsler from Germany, is the first ever taken of this faint object. Typical for planetary nebulae is a compact envelope of H-alpha and OIII surrounding a tiny white dwarf. Coordinates: 19:18:50.58 + 03:27:20.82 Constellation: Aquila Size: 2.4 arcminutes This was a joint data capture project with my good friend Sven Eklund, with data captured on both my dual rig of 6" refractors and his C14 EdgeHD - all located at Fregenal de la Sierra in Southern Spain.

Image Description and Details : 15 hours on NGC7000/IC5070 from the backyard with a 75mm refractor and QHY600MM! My first attempt at this target a few years ago was terrible so I couldn't wait to shoot it again. Spent 3 nights, one for each narrowband filter, and am happy with the result despite it being "only" 15 hours total.

Image Description and Details : IC4685 can be found in the constellation of Sagittarius, very close to and often shown as part of the Lagoon Nebula. This area is rarely imaged on its own because of the more common photographic targets of M8 (Lagoon) and M20 (Trifid) being much more dominant in this area. The estimated distance is about 4000 light years away. The area of the image contains both emission and reflection nebulae and the open star cluster NGC 6546.

Image Description and Details : RCW 113, also called Gum 55, is a huge emission nebula (H II-region) in the constellation Scorpius, located in the neighboring Sagittarius Arm of the Milky Way. Its core ionising open cluster NGC 6231 is part of young, bluish stars known as the Scorpius OB1 association. This Sco OB1 association contains many star-forming areas with young, energetic stars of spectral class O & B. In this field of view other interesting deep sky objects are visible. The two bright stars to the left of NGC 6231 are zeta1 and zeta2 Scorpii. The Prawn Nebula (upper right, with blue hues), also known as IC 4628, is an emission nebula around 6,000 light-years from Earth. To the right of IC 4628 there is another open cluster NGC 6242. The Wolf or Fenrir Nebula (SL-17), @ 10 o’clock position in this image, is a dark nebula of dust and gas hiding the background stars. The Dark Tower (SFO 82) is the prominent bright-rimmed cometary globule, about 1.5 degrees away from NGC 6231 and Zeta Scorpii. The shape of this massive structure of cosmic dust resembles a dark tower emerging from the star field background. Most of these objects lie at a distance between 5,300-6,000 light-years from Earth.
