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.

 Info:
 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.
