Messier 57 – The Ring Nebula of Lyra

M57 (NGC 6720) is probably one of the most recognizable Messier objects. It is a planetary nebula found in the constellation Lyra, referred to as the Ring Nebula, and lies about 2,300 light-years from Earth.

From Wikipedia, “Such objects are formed when a shell of ionized gas is expelled into the surrounding interstellar medium by a red giant star, which was passing through the last stage in its evolution before becoming a white dwarf.”

This image is composed of 60 x 15 second images at ISO 3200 with additional dark and bias frames. Tech Info: Meade LX90 12” telescope, Antares Focal Reducer, and Canon 6D camera. Imaging was done on July 27, 2016.

Messier 56 – Globular Cluster in the Constellation Lyra

M56 (NGC 6779) is a globular cluster located in the constellation Lyra. M56 is about 33,000 light-years from Earth and measures about 84 light-years across. Messier noted it as, “nebula without stars and having little light.”

This image is composed of 20 x 15 second images at ISO 3200 with additional dark and bias frames. Tech Info: Meade LX90 12” telescope, Antares Focal Reducer, and Canon 6D camera. Imaging was done on July 27, 2016.

The Vallis Alpes (Alpine Valley) on the Moon

Here is an interesting formation I never looked up before, it is called the Vallis Alpes, or Alpine Valley. It is a valley that bisects the Montes Alpes range and runs from Mare Imbrium to Mare Frigoris. This feature is over 80 miles in length and widens to almost 6 miles.

Messier 27 – The Famous Dumbbell Nebula

The Dumbbell Nebula (Messier 27, M27 or NGC 6853) is a bright planetary nebula in the constellation Vulpecula. It is easily seen in binoculars and wide-field photographs. The central star is an extremely hot blueish subdwarf. The nebula was created by the dying star ejecting a shell of gas into space.

Galaxy NGC 5907 – The Splinter Galaxy of Draco

I photographed this galaxy on the night of July 27, 2016 at the very end of my observing session. I looked at Starry Nights Pro and noticed a galaxy called the Splinter Galaxy (NGC 5907) and aimed the scope in its direction. The image shown is just five minutes of collected data. This galaxy is about 50 million light years away.

Deep exposure imaging of this galaxy has revealed tidal streams of stars surrounding the galaxy – beyond the grasp of my setup.
