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.

Sharpless 132 is a very faint emission type nebula on the Cepheus/Lacerta border. It lies at a degree southeast of Epsilon Cep, and has a size of about 40 arc minutes.

Sh2-132 is located at about 10400 light years in the Perseus Arm of the Milky Way , in the region of Cepheus OB1, a large, bright OB association . The stars responsible for the ionization of its gases are very hot and massive; in particular, two Wolf-Rayet stars , known by the initials HD and HD 211 564 211 853 (the latter also having the initials WR 153), as well as a star of spectral class O8.5V and a dozen stars of class B.

Here is 47 Tucanae, AKA NGC 104 from some time I booked on a telescope in Chile. It was harder than I thought it would be to process. This is a total of 1 hour and 40 minutes of exposure after I tossed 30 minutes of L due to 300s subs absolutely destroying the core of this. I wish I had done 2x more of R, G, and B rather than the 6x L. Still, it's a really cool looking glob!

The Horsehead is one of the most famous nebulae on the sky. The horse-head feature is dark because it is really an opaque dust cloud that lies in front of the bright emission nebula. Like clouds in Earth's atmosphere, this cosmic cloud has assumed a recognizable shape by chance. After many thousands of years, the internal motions of the cloud will surely alter its appearance. The emission nebula's color is caused by electrons recombining with protons to form hydrogen atoms. On the image left is the Flame Nebula that also contains filaments of dark dust. Just to the lower left of the Horsehead nebula is a blueish reflection nebulae that preferentially reflects the blue light from nearby stars.

WR 134 is a Wolf-Rayet star in Cygnus which is around 6,000 light years distant. It shines at 400,000 times the luminosity of the sun. Intense radiation and stellar winds have created a bubble of gas around the star. In this image the bubble is seen in blue/green doubly ionized oxygen (OIII) light. A large amount of hydrogen (HII) emission is also displayed as the red areas. The star responsible for this is near the center of the bubble and is whiteish. The image was taken with my #Stellarvue SVX 152T refractor and #zwoasi 6200 camera through RGB and HII/OIII filters. The image combines a bit over 47 hours of exposure time. Automation was controlled with a #primalucelab Eagle 4 pro and Voyager Astrophotography Automation software. The image is cropped and rotated for a pleasing view.

The Cave Nebula lies in the constellation Cepheus about 2,400 light years away, pretty close in cosmic terms. The “cave” has a bright rim ionized by the hot blue-white stars in the vicinity. The main “cave” structure is 10 light years across and is catalogued as Sharpless 155 (Sh2-155) and also as Caldwell 9 (the Caldwell catalogue was compiled by Sir Patrick Moore, and named for his mother’s maiden name). Near the lower left corner of the image is a blue reflection nebula, vdB 155. The Cave Nebula region makes a nice natural colour image, highlighting red emission nebula, blue reflection nebulae, dark nebulae and many colourful stars. I’ve also imaged the Cave Nebula before at higher resolution; that image was publishedin the April 2016 issue of Sky and Telescope.

The Belt of Orion or the Belt of Orion is an asterism in the constellation Orion. It contains three bright stars Alnitak, Alnilam and Mintaka.

The Orion Belt is easy to find in the night sky, as it is located on the celestial equator and is part of one of the most prominent stellar patterns in the northern sky, the hourglass-shaped constellation Orion. The asterism and constellation are visible in the northern latitudes from November to February.

This is an image made with an Epsilon 180 ed telescope, on an Atlas mount, Orion, PHP guidance system and a Canon EOS Ra camera.

Data acquisition is 120 images of 60 seconds, plus Bias, Darks and Flats.

mage Description and Details : I present to you an exotic object that was initially discovered as a planetary nebula but was requalified as a supernova afterglow that occurred over 7,500 years ago.
Located about 10,000 light years from home towards the Cassiopeia constellation, these are the filamentary remnants of a supernova that have a shell shape, part of which is doubly ionized oxygen (in blue) while the rest (in red) is essentially ionized hydrogen.
