About:
Do you see a horse? That large dark nebula, called The Dark Horse, lies in the equatorial constellation Ophiuchus, near its borders with the constellations Scorpius and Sagittarius. It is a significant, visible feature of the Milky Way's Great Rift, present in every photo of the central Milky Way. It can be visible from Earth on clear nights without moon, light pollution and with low humidity, creating a dark shape in a star field. The rear of the Great Dark Horse is also known as the Pipe Nebula.

Enriched with the Lagoon, Trifid, Omega and Eagle Nebulae, this photo aims to point out the grandeur of the universe.

Technique:
This photo is a composite taken from the same place and at the same night. The only change is the focal length. Picture of the sky was taken with 135 mm lens, and is a mosaic made of 30 single-shot panels. Foreground picture with my beloved wife holding a lantern is a single-shot taken with 35 mm lens. This composite is not in a scale, the sky is little bit bigger, because I couldn't transform it any more to match with my foreground size is like 90% accurate.

Full Moon of Corfu - The Two Fortresses

Rise of the Full Moon of September between the two Venetian Fortresses of the old town of Corfu.
The moon is about 397655km away, while the city of Corfu is about 3.5km away.

Sh2-115
Sharpless 115 stands just north and west of Deneb, the alpha star of the constellation Cygnus, the Swan. Noted in the 1959 catalog by astronomer Stewart Sharpless (as Sh2-115) the emission nebula lies along the edge of one of the outer Milky Way's giant molecular clouds, about 7,500 light-years away. Hot stars in star cluster Berkeley 90 power the nebular glow. The cluster stars are likely only 100 million years old or so and are still embedded in Sharpless 115.
The small blue object, is Abell 71. The nebula is also cataloged as PK 085+04.1, PN G084.9+04.4 and Sh 2-116. Initially cataloged as a planetary nebula, the object is now recognized as a small patch of HII emission.

To the Far Side of the Moon--rare views from Earth

To the Far Side of the Moon--rare views from Earth by Tom Glenn, on Flickr

Full resolution:
https://live.staticflickr.com/65535/502 ... 7582_o.jpg

This image was taken at maximum libration in both latitude (south) and longitude (east), and therefore shows many features that are rarely observed from Earth. Of special interest in this image are the following features:

1. Shackleton crater, marking the true lunar South Pole.
2. Schrodinger crater (rim visible), a far side impact basin
3. Vallis Schrodinger, a long linear valley on the lunar far side.
4. Numerous far side craters visible near the limb (more details below).

Shackleton crater, marking the true South Pole of the Moon, is visible at the top right of the image, although locating it among the complex crater strewn landscape is not so simple. The rim of Shackleton is partially illuminated, whereas the interior experiences perpetual darkness. To the left of Shackleton, the elevated terrain on the lunar limb marks the perimeter of Schrodinger crater, a large impact basin on the lunar far side. The far side craters Ganswindt and Idel'son are clearly visible here, with Rittenhouse further to the left. Further still to the left, some features of Vallis Schrodinger can be observed on the extreme limb. Vallis Schrodinger is a linear valley on the lunar far side that likely formed during the Schrodinger impact. Vallis Schrodinger crosses through the far side crater Sikorsky, which is partially visible on the extreme limb of the image. Far side craters Chamberlin and Moulton (visible towards left of image, along the limb) lie at the northern terminus of the valley. And finally, at the far left of the image, we see the edge of Mare Australe. Other notable features in the image include Vallis Rheita at lower left, Boussingault crater near top center (large crater with multiple terraces), polar craters Amundsen and Scott at top right, and a series of striking craters along the lunar terminator.

The image was captured with a C9.25 Edge HD telescope, ASI183mm camera, and 610nm long pass red/IR filter on July 20, 2018, at 03:17UT, from San Diego, CA. Focal length 2350mm @f/10. Stack of 500 frames. Software utilized: Autostakkert (version AS!3 for stacking), PixInsight, Photoshop.

Hi every tout le monde !

We can see behind the stars in the foreground a multitude of small spots, they are galaxies ...
I didn't count the numbers, you won't mind me, eh .

I had fun taking it over 3 nights, about 12 hours of integration.

You can feel the limits of the camera.

Sh2-216 - Sh2-221

Stars’ Lifecycles Play Out in One Patch of Sky

Sh2-221 and Sh2-216, to the left and right respectively, resulted from different types of star deaths. Sh2-221, at an approximate age of 6,000 years old, is a supernova remnant (SNR). The planetary nebula (PN) Sh2-216, aged at nearly 500,000 years old, has grown exceedingly dim, and its fuzzy edges indicate that it is beginning to dissipate. SNR Sh2-221 is roughly 2,600 ly away and about 130 ly across, while PN Sh2-216 is approximately 400 ly away and 11 ly wide. Therefore, PN Sh2-216 is much closer and smaller in actual size than SNR Sh2-221.

The three smaller objects: Near the top left are two bright orange nebulae; the larger is Sh2-217 and the smaller--which appears to rest on the shoulder of Sh2-221--is Sh2-219. At the bottom center is nebula BFS 44. These three emission nebulae are all part of the same star forming region.

Hi everyone, this is my first post



You can check the full resolution one and acquisition data on Telescopius

It's very common that big DSO objects are photographed as a whole and usually a lot of beautiful filaments detail is lost. I've centered my attention on the Williamina Fleming's Triangular Wisp area also known as the Pickering's triangle.

Sivan 2 by Jeffrey Lovelace, on Flickr

The first successful narrowband tricolor image of Sivan 2?

Little is known about the nebula Sivan 2 (Siv 2) beyond it lying approximately 1380 parsecs (4500 light years) away and being an HII region. To my knowledge there are only a small number of previous images of this subject. Of those, the earliest is when it was identified in a 1974 Hα sky survey by astrophysicist Jean-Pierre Sivan (http://articles.adsabs.harvard.edu/full ... ..16..163S ). it also appears in the ongoing Hα MDW Sky Survey (https://www.mdwskysurvey.org/). The other more targeted images, though groundbreaking in their own ways, are either broadband RGB or RGB + Hα; and as such they can show only a vague reddish haze.

Sivan 2 is indeed a very faint target. This image integrates 12 hours each of Hα, SII, and OIII data (all filters 3nm). I also captured a few hours or broadband RGB to produce properly calibrated stars.

This is an HSO image in which (Hα) is mapped to the red channel; SII is green, and OIII is blue. The areas with both abundant red Hα and green SII combine to create strong golden tones of course; but with the stronger Hα in the red position there are descent reds as well where only Hα exists, unlike in SHO (Hubble palette) images.

Aside from the aesthetics, this tricolor NB image reveals details about Sivan 2’s gaseous structure entirely missed in earlier photographs. The surprising relative abundance of OIII might indicate a specific evolution of this area, perhaps as an ancient planetary nebula; but I will leave that hypothesis to the astrophysicists.

Hello to you,

Please find attached the Cocoon Nebula.

This nebula is almost 15 light-years wide and located 4,000 light-years away. This image illustrates how the bright star near the center of the Cocoon Nebula is powering the intense nebular glow, and clearing out a cavity in the areas of star-forming dust and gas.

This nebula is comprised of a molecular cloud, which is a giant condensation of dust and molecular gas. All stars are born in molecular clouds, and typically stand out in red, glowing hydrogen gas as seen in the Cocoon Nebula. The Cocoon Nebula is considered to be one of many “stellar nurseries“, as this is where new stars are being born.
