IC5146 - Cocoon Nebula

"IC 5146 (also Caldwell 19, Sh 2-125, and the Cocoon Nebula) is a reflection/emission nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula. The cluster is also known as Collinder 470. It shines at magnitude +10.0/+9.3/+7.2. Its celestial coordinates are RA 21h 53.5m, dec+47° 16′. It is located near the naked-eye star Pi Cygni, the open cluster NGC 7209 in Lacerta, and the bright open cluster M39. The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago; the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years. When viewing IC 5146, dark nebula Barnard 168 (B168) is an inseparable part of the experience, forming a dark lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon"

*C/2013 US10 Catalina *

"C/2013 US10 (Catalina) is an Oort cloud comet discovered on 31 October 2013 by the Catalina Sky Survey at an apparent magnitude of 19 using a 0.68-meter (27 in) Schmidt–Cassegrain telescope. 
When discovered on 31 October 2013 observations from another object from 12 September 2013 were used in the preliminary orbit determination giving an incorrect solution that suggested an orbital period of only 6 years. But by 6 November 2013 a longer observation arc from 14 August until 4 November made it apparent that the first solution had the wrong object from 12 September.
The comet came to perihelion (closest approach to the Sun) on 15 November 2015 at a distance of 0.82 AU from the Sun. At perihelion, it had a velocity of 46.4 km/s (104,000 mph) with respect to the Sun which is slightly greater than the Sun's escape velocity at that distance. It crosses the celestial equator on 17 December 2015 becoming a northern hemisphere object. On 17 January 2016 the comet will pass 0.72 AU (108,000,000 km; 67,000,000 mi) from Earth and should be around magnitude 5.5 while located in the constellation of Ursa Major.

C/2013 US10 is dynamically new. It came from the Oort cloud with a loosely bound chaotic orbit that was easily perturbed by galactic tides and passing stars. Before entering the planetary region (epoch 1950), C/2013 US10 had an orbital period of several million years. After leaving the planetary region (epoch 2050), it will be on an ejection trajectory."

EPHESUS ANTIQUE CITY

Ephesus (/ˈɛfəsəs/; Greek: Ἔφεσος Ephesos; Turkish: Efes; ultimately from Hittite Apasa) was an ancient Greek city on the coast of Ionia, three kilometres southwest of present-day Selçuk in İzmir Province, Turkey. It was built in the 10th century BC on the site of the former Arzawan capital by Attic and Ionian Greek colonists. During the Classical Greek era it was one of the twelve cities of the Ionian League. The city flourished after it came under the control of the Roman Republic in 129 BC. According to estimates, Ephesus had a population of 33,600 to 56,000 people in the Roman period, making it the third largest city of Roman Asia Minor after Sardis and Alexandria Troas.

The city was famed for the Temple of Artemis (completed around 550 BC), one of the Seven Wonders of the Ancient World. In 268 AD, the Temple was destroyed or damaged in a raid by the Goths. It may have been rebuilt or repaired but this is uncertain, as its later history is not clear. Emperor Constantine the Great rebuilt much of the city and erected new public baths. Following the Edict of Thessalonica from Emperor Theodosius I, what remained of the temple was destroyed in 401 AD by a mob led by St. John Chrysostom. The town was partially destroyed by an earthquake in 614 AD. The city's importance as a commercial center declined as the harbor was slowly silted up by the Küçükmenderes River.

Ephesus was one of the seven churches of Asia that are cited in the Book of Revelation. The Gospel of John may have been written here. The city was the site of several 5th century Christian Councils (see Council of Ephesus). It is also the site of a large gladiators' graveyard. The ruins of Ephesus are a favourite international and local tourist attraction, partly owing to their easy access from Adnan Menderes Airport."

NGC7023 - Iris Nebula

"The Iris Nebula, also NGC 7023 and Caldwell 4, is a bright reflection nebula and Caldwell object in the constellation Cepheus. NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +7 star, SAO 19158. It shines at magnitude +6.8. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across."

NGC 5907 - Knife Edge/Splinter Galaxy

"NGC 5907 is a spiral galaxy located approximately 50 million light years from Earth. It has an anomalously low metallicity and few detectable giant stars, being apparently composed almost entirely of dwarf stars. It is a member of the NGC 5866 Group.

NGC 5907 has long been considered a prototypical example of a warped spiral in relative isolation. Then in 2006, an international team of astronomers announced the presence of an extended tidal stream surrounding the galaxy that challenges this picture and suggests the gravitational perturbations induced by the stream progenitor may be the cause for the warp.

NGC 5907 is also known as the Knife Edge or Splinter galaxy."

Messier 31 - The Great Andromeda Galaxy
Two Panel Mosaic.

"The Andromeda Galaxy /ænˈdrɒmɨdə/ is a spiral galaxy approximately 2.5 million light-years (2.4×10^19 km) from Earth in the Andromeda constellation. Also known as Messier 31, M31, or NGC 224, it is often referred to as the Great Andromeda Nebula in older texts. The Andromeda Galaxy is the nearest spiral galaxy to our Milky Way galaxy, but not the nearest galaxy overall. It gets its name from the area of the sky in which it appears, the constellation of Andromeda, which was named after the mythological princess Andromeda. The Andromeda Galaxy is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 44 other smaller galaxies.

The Andromeda Galaxy is probably the most massive galaxy in the Local Group as well, despite earlier findings that suggested that the Milky Way contains more dark matter and could be the most massive in the grouping. The 2006 observations by the Spitzer Space Telescope revealed that M31 contains one trillion (10^12) stars: at least twice the number of stars in the Milky Way galaxy, which is estimated to be 200–400 billion.

The Andromeda Galaxy is estimated to be 1.5×10^12 solar masses, while the mass of the Milky Way is estimated to be 8.5×10^11 solar masses. In comparison a 2009 study estimated that the Milky Way and M31 are about equal in mass, while a 2006 study put the mass of the Milky Way at ~80% of the mass of the Andromeda Galaxy. The two galaxies are expected to collide in 3.75 billion years, eventually merging to form a giant elliptical galaxy or perhaps a large disk galaxy.

At 3.4, the apparent magnitude of the Andromeda Galaxy is one of the brightest of any Messier objects, making it visible to the naked eye on moonless nights even when viewed from areas with moderate light pollution. Although it appears more than six times as wide as the full Moon when photographed through a larger telescope, only the brighter central region is visible to the naked eye or when viewed using binoculars or a small telescope."
