The Triangulum Galaxy is a spiral galaxy approximately 3 million light years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a nickname it shares with Messier 101.

Information about Sh2-101
The Tulip Nebula, or Sharpless 101 (Sh2-101) or the Cygnus Star Cloud is an emission nebula located in the constellation Cygnus. It is so named because it appears to resemble the outline of a tulip when imaged photographically. It was catalogued by astronomer Stewart Sharpless in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years (5.7×1016 km; 3.5×1016 mi) from Earth.The Tulip nebula, at least in the field seen from earth, is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes. Cygnus X-1 is the brighter of the two stars (lower star) in close vertical proximity just to the right of the Tulip nebula.

Information about NGC 6888
The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light years away.It was discovered by Friedrich Wilhelm Herschel in 1792.[2] It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000[citation needed] years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures.

This small but bright nebula is a good object for those with a small field of view. Using a larger telescope will reveal the fine details and structure. The object responds very well with the hydrogen-alpha filter and makes a great HA-RGB image, but you need a lot of color to colorize the nebula. The nebula also responds very well to Sulfur II and Oxygen III, so this is a good one for a color narrowband image. A wider field of view will pick up the nebula around this object as well as the nearby object SH2-115.

Information about m 27
The
Dumbbell Nebula (also known as Apple Core Nebula, Messier 27, M 27, or
NGC 6853) is a planetary nebula in the constellation Vulpecula, at a
distance of about 1,360 light years.
This object was the first planetary nebula to be discovered; by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and its diameter of about 8 arcminutes, it is easily visible in binoculars, and a popular observing target in amateur telescopes.
The Dumbbell Nebula appears to be shaped like an prolate spheroid and is viewed from our perspective along the plane of its equator. In 1992, Moreno-Corral et al. computed that its rate of expansion in the plane of the sky was no more than 2″.3 per century. From this, an upper limit to the age of 14,600 yr may be determined. In 1970, Bohuski, Smith, and Weedman found an expansion velocity of 31 km/s. Given its semi-minor axis radius of 1.01 ly, this implies that the kinematic age of the nebula is some 9,800 years.

Information about 6960
The
Veil Nebula is a cloud of heated and ionized gas and dust in the
constellation Cygnus. It constitutes the visible portions of the Cygnus
Loop (radio source W78, or Sharpless 103), a large but relatively faint
supernova remnant. The source supernova exploded some 5,000 to 8,000
years ago, and the remnants have since expanded to cover an area roughly
3 degrees in diameter (about 6 times the diameter, or 36 times the
area, of the full moon).
The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light-years.
The Hubble Space Telescope captured several images of the nebula. The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen. This is also one of the largest, brightest features in the x-ray sky.
