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.

LDN 1082 or Barnard 150, also known as Seahorse Nebula because of its striking appearance, is an extended, elongated dark molecular cloud of dust in Cepheus constellation, so thick, that it absorbs all the light that comes from the stars behind it. This molecular cloud is part of our Milky Way galaxy, one of the 182 objects cataloged by astronomer Edward E. Barnard and it lies at about 1200 Llight -years away. Cloud location on the Milky Way's plane, makes it stand out on the background completely filled with colorful stars of any age and size.

This nebula is about 1 degree in size, width of two Moons. What is also interesting about this cloud, as it have 3 highly dense dust cores, which actually is a star formation regions. They were cataloged by Lynds and named LDN 1082 A, B and C.

Because the molecular cloud is only illuminated from behind by starlight, it is a major challenge for astrophotographers to process the dark dust on a dark background. To make things easier, nebulae of this type require very dark skies, so I was skeptical about the success of the photo from a polluted city sky (Bortle 7, SQM 19). The result surprised me quite a bit, also considering that this nebula is still low in this period.
