Image Description and Details :Heckathorn-Fesen-Gull 1 (HFG1) and Abell 6 are a duo of planetary nebulae from the constellation Cassiopea.
The central star of HFG1 is a 14.5 mag binary star. It leaves behind a gas tail of at least 20 '. She is said to be around 10,000 years old.
The structure of HFG1 presents an arc of a circle opposite the tail, in the direction of movement of the nebula, which suggests that it is a shock wave front of matter interacting with the interstellar medium.

Abell 6 is an example of a bubble-shaped planetary nebula. However, it remains quite faint (Mag = 15). It emits more in OIII than in Ha.

Image Description and Details : We are very proud to present Patchick-Strottner-Drechser 8 (PaStDr for short) the latest discovery of our team consisting of Dana Patchick from the US, Xavier Strottner from France and Marcel Drechsler from Germany.

6 MONTHS OF WORK, 68 NIGHTS AT THE CHILESCOPE AND 133 HOURS OF EXPOSURE TIME WERE NECESSARY TO IMAGE THIS EXTREMELY FAINT NEBULA.

Our discovery is a previously unknown potential planetary nebula in the constellation Sagittarius.
The structure has a diameter of almost one degree in the night sky and a distance of about 840 light years to Earth.

The special feature of this photo are the extremely filigree and blood red filaments of the supernova remnant G354-33, which can be seen in the left part of the image. This is the first photo ever taken of this almost unknown supernova remnant. In 2004 G354-33 was mentioned as a possible SNR in a scientific paper. However, with our work we were able to confirm G354-33 as a true SNR.

The scientific paper on this SNR, on which we worked with Professor Robert Fesen of Dartmoor College, can be found here:
https://arxiv.org/pdf/2102.12599.pdf

It is noteworthy that PaStDr 8 does not appear approximately spherical as usual, but appears much brighter and denser in the west (note, in the night sky the west is shown on the right and the east on the left).
We suspect that the structure of this candidate interacts with supernova remnant G354-33 or is distorted by its shock.
Measurement of the distance between the two structures suggests spatial proximity.

Our thanks to Sergey from Chilescope, who strongly supported us with this project.
We would also like to give special thanks to the many donors without whom this costly photograph would never have been possible. Especially the residents of my home community Bärenstein in Germany should be mentioned here, who also supported our project financially. We thank you so much!

Image Description and Details : This dark nebula lies at a distance of 1200 light-years from Earth in the Constellation of Cepheus. Because the nebula is in the Milky Way's plane it stand outs from the background filled with colourful stars of our galaxy, a keen eye can also distinguish three separate dense dust cores that actually are star formation regions.

Image Description and Details :

NGC 7582, 7590 and 7599 are an interacting group of galaxies situated 70 million light years away in the constellation of Grus.
Studies in indicate the existence of faint H I bridges between the galaxies.
NGC 7582 at the top right is the brightest galaxy of this trio. It is of interest as it exhibits the characteristics of both a starburst and a Seyfert II spiral galaxy. The starburst activity is quite intense but is localized to several regions.
In 1996 a study indicated that NGC 7582 appears to have two rather than a single nuclei indicating a merger with another galaxy sometime in the distant past.

Image Description and Details : IC 1340, otherwise known as The Bat Nebula and Caldwell 33, is a beautiful portion of the Cygnus loop supernova remnant that reveals delicate wisps and filaments of nebulosity. Sadly, it is often overlooked because of the notoriety of three other portions of the Cygnus loop, namely the Veil Nebula, The Witch's Broom Nebula, and Pickering's Triangle. IC 1340 is the continuation of the Veil Nebula. The nebula lies approximately 1,500 light-years from Earth.

PM1-320 is a small planetary nebula in Cygnus, close to DWB 111, the Propeller Nebula.
It was discovered by Andrea Preite-Martinez in the 1980s.
I believe this to be the first deep high-resolution image of PM1-320.
The outer parts of the nebulosity are very faint, hence 56 hours of OIII integration.
HASH records it's size as 60 arc seconds.

Image Description and Details :

Rupes Recta is a linear fault on the Moon, in the southeastern part of the Mare Nubium. The name is Latin for straight cliff, although it is more commonly called the Straight Wall. This is the most well-known escarpment on the Moon, and is a popular target for amateur astronomers.

When the sun illuminates the feature at an oblique angle at about day 8 of the Moon's orbit, the Rupes Recta casts a wide shadow that gives it the appearance of a steep cliff. The fault has a length of 110 km, a typical width of 2–3 km, and a height of 240–300 m. Thus although it appears to be a vertical cliff in the lunar surface, in actuality the grade of the slope is relatively shallow.

To the west of this escarpment is the crater Birt, which is about 17 km in diameter. The Birt Rille is a slightly curved ~50 km long channel that starts and ends in a pit.

The Cave Nebula (Sh2- 155 or Caldwell 9) is an emission nebula of the Cepheus constellation.
It is a weak light nebula and very diffuse in a greater complex of nebula containing dark emission, reflection and nebulosity. It is located in the constellation of Cepheus and is about 2400 light years from Earth.
