Image Description and Details : I took this Picture from the ISS on May the 19. at 0h29m04s MESZ from my Balkony in Hamm / Western Germany / Ruhrgebiet.
My Teleskop was an Explore Scientific 10 Inch Dobson with f/5
The Camera was a Asi 178mm with a cheap 2x Barlow

I once labeled a few parts of the ISS. I hope I got it right.

Image Description and Details : The Propeller nebula (also known as DWB 111 or Simeis 57) is a emission H-alfa nebula in Cygnus constellation in the center of a triangle made by Deneb, Sadr and Delta-Cyg.
DWB and Simies designations are not so commonly known. The Simeis Catalog was created in the 1950s by the Crimean Astrophysical Observatory in Simeis, Ukraine. This catalog is focused on HII regions and documented 306 of them. The Propeller Nebula is item 57 in this catalog.
The DWB catalog was created in the 1960s by H. R. Dickel, H. Wendker, and J. H. Bieritz, and it cataloged the HII regions they were studying in the Cygnus X Complex. While DWB 111 is often used as the designation for the Propeller, it only deals with the southern arm of the Propeller, while DWB 119 deals with the northern arm. So you can call the Propeller Nebula DWB 111/119 or Semeis 57.

Messier 82 was discovered in 1774 by Johann Elert Bode, rediscovered by Pierre Mechain August 1779 who reported them to Charles Messier, who added them to his catalog in 1781.

M 82 is the prototype irregular starburst disk galaxy. In the core of M 82, the active starburst region spans a diameter of 500 parsecs.

Tendrils of material extend away from the nucleus, suggesting a colossal explosion. Studies have revealed filaments expanding outward from M 82 at 600 miles per second.

Image Description and Details : During May 6 2023 i imaged the Lacus Veris Lacus Autumni Schluter and the Montes on the lunar limb as in previous image. The region into account was selected and studied for identification of the features here enclosed and compared with WAC LRO imagery. some peaks of this region were identified, according to the work of Vandenbohede (J. Br. Astron. Assoc. 132, 2, 2022). The location is shown based on favourable libration.

IC 2948 - The Heart of the Running Chicken Nebula.

Hello everyone, we reached the middle of the week and I am going to leave here this image of another object located in the southern hemisphere and that I finished yesterday, I hope you like it and you all have a very good day.

The image covers IC 2948 and part of IC 2944, it is located in the constellation of Centaurus, very close to the star λ Centauri.

IC 2948 is the brightest emission and reflection nebula, located within the nebula but to the southeast of the Running Chicken Nebula. IC 2948 harbors several Bok globules, although this time here called Thackeray globules in honor of their discoverer, these globules made of dust and gas are places where active star formation usually occurs.

It is separated from us by approximately 6,500 light years.

Image Description and Details : The Pencil Nebula is an emission nebula in the constellation Vela. It’s a small part of a supernova remnant that exploded about 11,000 years ago. The pencil-like shape suggests that it is part of the supernova shockwave that encountered a region of dense gas. It’s that intersection that causes the nebula to glow. The colors of the various regions in the nebula yield clues about this cooling process. Some regions are still so hot that the emission is dominated by ionized oxygen atoms, which glow blue/green in the picture. Other regions have cooled more and are seen emitting red in the image (cooler hydrogen atoms). In this situation, color shows the temperature of the gas.
The image was acquired over 9 days between 4/14/23 and 5/5/23 with total integration time of about 38 hours. It was processed in the HOO palette with RGB for the stars.

Image Description and Details : We have photographed the LDN 1400 object that hides the SNR G150.3+4.5, aka "Thor's Lightning."
A collaboration on data acquisition allowed us to highlight the SNR signal but also to unveil an OIII shell around the star "CI Camelopardalis".
The StDr team, which supported us on this project, analyzed our data and helped us to register this discovery, allowing us to open the Martino-Sainty Object (MarSai O) catalog
MarSai O 1 was named the "Angelo's Nebula", in homage to my father.

Image Description and Details : Also the fourth stage of the ShaRA project, with which we occasionally go on a remote trip to the southern hemisphere to film some marvel of that marvelous sky, has recently concluded. ShaRA#4 was characterized by the multitude of shots taken but in this post I show you only the first part that featured the extended nebulae Gum 14 and Gum 15 and the small planetary nebula He 2-11, of which we made the first ever amateur shot and which we renamed the Spin Nebula.

Gum 14/15 are two little photographed nebulae in the constellation of Vela and apparently linked to each other. Gum 14, the largest, is an emission nebula excited by a class O blue supergiant and prospectively adjacent to a complex of reflection nebulae whose most important is NGC 2626. Gum 15 is another emission nebula which, together with Gum 14 belongs to the Vela Molecular Ridge: a mega molecular complex full of young and hot stars, which thanks to their radiation, becomes visible to our telescopes.
He 2-11 is a planetary nebula about 2300 light years away, with the rare peculiarity that its nucleus is characterized by a variable binary system. He 2-11 has a structure characterized by a uniform central core of OIII and two filamentous outer protuberances of low ionization H-alpha.

M 13 is 145 light-years in diameter and composed of between 300,000, to more than half a million gravitationally bound stars in the constellation of Hercules.

It’s a spectacular star cluster to see in a telescope with its super bright core of hot blue stars.

Image Description and Details : M17 Omega Nebula

The Omega Nebula (also known as the Swan Nebula, Horseshoe Nebula, Lobster Nebula or with the catalog codes M 17 and NGC 6618) is an emission nebula, discovered by de Chéseaux in 1746 and rediscovered by Charles Messier in 1764, located in the constellation Sagittarius.
Thanks to its luminosity, the Omega Nebula is quite easy to locate: it is located 2° southeast of the star γ Scuti. it can be identified quite easily even with 10x50 binoculars or even smaller, if the sky is dark and clear: in these instruments it appears as an elongated spot; through a 114 mm instrument, equipped with a UHC filter, it reveals a good part of its nuances and plays of light. From 200mm onwards the vision is exceptional, and it is advisable to take a long exposure photo to capture the rosy colour.

Constellation: Sagittarius
Right Ascension :18h 20m 26s
Declination : -16° 10′ 36″
Distance : about 6000 a.l.
Apparent magnitude: 6.0

This magnificent nebula was taken by my friend Gianni Lacroce. There are just under two hours of shots taken with a zwo ASI 2600 MC camera, a camera given to Gianni by a shopkeeper near Rome to test it. The owner had the doubt of a malfunction (later revealed not to be present). Talking about his performance, I asked him if I could elaborate these few shots and he kindly granted me the integration master.
