Image Description and Details :

This cosmic pillar stretches for approximately 1,400 light years along the northern part of the Milky Way, in the constellation Cepheus. Near the edge of the large molecular cloud, pockets of dust block all light from the stars in the background or weaken the light of the brightest star at the top, this star giving the nebula its characteristic blue color.At the bottom right of the image is a planetary nebula LBN 538 (red / blue).

Image Description and Details : IC 1318 taken in South Portugal.
IC 1318 also called the Butterfly Nebula, is a nebula in emission in the constellation Cygnus.

It is a huge nebula in emission, quite bright and distinct, in the shape of a circumflex accent, rather difficult to see, but which appears easily on photographs. It has in its center a dark nebula. It spreads around the bright star Sadr (γ Cygni). It is located in the Milky Way, thus on a background rich in stars.

Image Description and Details : IMPACT on the planet Jupiter
=========================
On 13.09.2021, I made a series of exposures to the transit of the IO satellite over the planet Jupiter.
Towards the end of the observation session, I noticed a large rapid spark in the IR filter, but I did not realize its importance until, the next day, the Brazilian amateur observer José Luis Pereira also discovered it in his captures and
he made it public. The seeing was good that night, but at the time of the impact it had dropped considerably.
Processing was required to combine the exposures made on the IR filter, in which the impact occurs, with the rest of the filters,
green and blue, to achieve a color image. The capture was made with a monochrome ZWO ASI 290MM camera, the exposure video being 2000 x3 frames on each filter.
The derotation of the SER videos was performed in the WinJUPOS program, the total duration being 14 minutes.
Although I am the beginning of the exposures to the planets, being focused on the deepsky pictures, I think I was very lucky to catch this event.
I want to thank Dm. astrophotographer Pepe Mera, for the tips related to the optical part, which have a lot in mind in the realization
exposures to planets.

The Cepheus constellation part of the sky shows part of the Milky Way that host several star forming regions. One of the molecular clouds which spreads from 600 to around 1400 light years away from Earth and is named Cepheus Flare. Near one of Flare edges is the beautifully formed nebula vdB-141 also known as Sh2-136. “vdB” comes after Sidney van den Bergh who discovered the “dark” nature of the object in 1966. “Sh2”comes after from the second edition of Stewart Sharpless emission nebulae catalog published in 1959. It also has popular name “Ghost Nebula”.

Being part of star forming region means that many things are happening. It is a reflection nebula that shines with the light of several stars embedded in it, most obvious is the one in the central blob. In right dark part there is cone shaped area – this is a Bok globule cataloged as CB230. The Bok globules are dark clouds in process of condensing and forming protostars. CB230 is considered to be producing a binary star system. The same place is also cataloged as Herbig Haro object HH 157. The Herbig Haro objects are nebulae around newborn stars that are formed in the nearby clouds by the ionized gas jets emitted by the young stars. It is an interesting area described in the results of different sky surveys.

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.
