IC 1795 SHO

IC 1795 is an emission nebula located about 6,000 light-years away in the constellation Cassiopeia.
The dominant central star of IC 1795 is a blue dwarf on the main sequence. In addition there are three other stars of class O and B with ages between 3 and 5 million years. This being an age intermediate to the 6 to 20 million years of the shell structure that encloses the complex. The region is one of the sites most studied (besides Orion) for the formation of massive stars. This area is more dense and rich in H II. It is home to, and hides, a group of young blue stars, with their radiation ionizing the residual gas clouds. (WIKI).

The Cave Nebula

The Cave Nebula ( Sharpless 2-155, Caldwell 9) is part of an extensive region of ionized hydrogen gas region. Sharpless 2-155 is a dim and very diffuse nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus and associated with the Cepheus B giant molecular cloud, laying at a distance of about 2800 light-years. Part of the cloud is illuminated by a pack of hot, young stars known as the Cepheus OB3 association.

Cave Nebula , the wild beauty of black and white

S 155, also known as the Cave Nebula, Sh2-155 or Caldwell 9, is a dim and very diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus.

Visually it is a difficult object, but with adequate exposure, makes a striking image. The nebula gets its name Cave Nebula from the dark lane at the eastern side abutting the brightest curve of emission nebulosity which gives the appearance of a deep cave when seen through a telescope visually.

M20 Trifid Nebula in narrowband

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764.[3] Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.

Photographic shots were completed in the period from 14 June  to 6 August and needed a total of 7 nights.

Unfortunately, in all the shots I had problem with passing clouds and high humidity .

Schroter's Valley

Schroter's Valley, frequently known by the Latinized name Vallis Schröteri, is a sinuous valley or rille on the surface of the near side of the Moon. It is located on a rise of continental ground, sometimes called the Aristarchus plateau, that is surrounded by the Oceanus Procellarum to the south and west and the Mare Imbrium to the northwest. At the southern edge of this rise are the craters Aristarchus and Herodotus.

This is the largest sinuous rille on the Moon. It begins at a 6 km diameter crater located 25 km to the north of Herodotus. (The start of the rille has been termed the "Cobra's Head" by some observers, due to its resemblance to a snake.) From the crater it follows a meandering path, first to the north, then setting a course toward the northeast, before finally bending back to the south until it reaches a 1 km high precipice at the edge of the Oceanus Procellarum. The rille has a maximum width of about 10 km, then gradually narrows to less than a kilometer near its terminus.

The origins of this rille are believed to be volcanic. The interior floor has been resurfaced and is very level. However there is a slender rille located on the floor, which can be photographed from Earth with a good telescope and good seeing.

The rille has been the subject of numerous transient lunar phenomena observations.

The selenographic coordinates of this valley are 26.2°N 50.8°W, and it has a maximum diameter of 168 km. It is named for Johannes H. Schröter.

It was a potential landing site for the canceled Apollo 18 mission

IC 410 The Tadpoles

IC 410 an emission nebula about 12,000 light-years from Earth in the constellation Auriga. Near the center of the nebulous region is a star cluster ( NGC 1893) and just to the bottom left of this cluster lies two structures that resemble tadpoles. These structures are made of leftover hydrogen and dust from the formation of the star cluster and the "tails" are from the solar wind coming from the stars of NGC 1893.

SH2-115 and Berkeley 90 Ha light

Sharpless 115 stands just north and west of Deneb. Noted in the 1959 catalog by astronomer Stewart Sharpless (as Sh2-115) the faint but lovely emission nebula lies along the edge of one of the outer Milky Way's giant molecular clouds, about 7,500 light-years away. Shining with the light of ionized atoms of hydrogen, sulfur, and oxygen in this Hubble palette color composite image, the nebular glow is powered by hot stars in star cluster Berkeley 90. The cluster stars are likely only 100 million years old or so and are still embedded in Sharpless 115. But the stars' strong winds and radiation have cleared away much of their dusty, natal cloud. At the emission nebula's estimated distance, this cosmic close-up spans just under 100 light-years.
