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.

Image Description and Details : NEW DISCOVERY: Strottner-Drechsler 16 is a new candidate of a planetary nebula in the constellation Aquila. 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.

Image Description and Details : NGC 6729 is a reflection/emission nebula (star-forming region) located some 424 light-years away in the constellation of Corona Australis (The Southern Crown). It is part of one of the closest stellar nurseries to Earth. The Corona Australis Molecular Cloud is a dusty dark molecular cloud just north of one of its two brighter stars Beta Coronae Australis. Within it are stars at the earliest stages of their lifespan. 7 x 10min Ha and 85 x 5min RGB subs @-10C were taken over 5 nights for a total integration time of about 8.3 hrs.

Image Description and Details:

Barnard 174 (=LDN1164) is a very dense dark nebula, which absorbs starlight behind the nebula. Infrared observations show many young stars in this region. Thus, B174 is an active star-forming region. Barnard 174 is a dark nebula in the constellation Cepheus. Dark nebulae or "fog" as they are sometimes called are clouds of cold gas, at temperatures near absolute zero (-273°C), located in cold, dense areas of larger molecular clouds . Their thickness obstructs the visible spectrum of stars or anything in its path. Only infrared and x-ray observations can be made through fog. The dark color is due to microscopic dust particles coated in frozen carbon monoxide and nitrogen, which block visible light.
