Deep Space Objects

My name is Bill Snyder, I have been interested in Astronomy since I was very young. I left the hobby for quite awhile and recently, about 9 years ago reacquainted myself with the stars. I am a member of the AAAP Amateur Astronomers Association of Pittsburgh Pa. and have my own Home Observatory. I have been involved with astrophotography since 2007 , and would like to share some of my images with you. I capture and process my own data (images) and also process other data from other observatory’s when available. Capturing the data is only half the battle. Once the images are taken with the camera and the telescope, it must be processed to produce the colorful images we see published in magazines and other media.

NGC 3576 contains several clusters as star propagation has progressed sequentially east to west during the last several million years. The bright emission component extends some 100 light years across and contains scattered small dark nebulae known as Bok Globules. Bok Globules are dense well defined concentrations of gas and dust named after the Dutch astronomer Bart Bok (1906-1983) who first defined them. Typically they possess 10 to 50 solar masses within a space of a single light year. Most commonly found within HII regions they are known to be cocoons of star formation, particularly the formation of double or multiple star systems. Text courtesy Rob Gendler. Thanks to Martin Pugh for data acquisition. (Bill Snyder) #

IC1396 - The Elephant Trunk Nebula in the constellation Cepheus is approximately 2,400 light years from Earth. This image is part of a larger region of nebulosity and star cluster IC1396. (Bill Snyder) #

IC434 - The Horsehead Nebula is approximately 1,500 light years from Earth in the constellation Orion. The Horsehead itself is a dark nebula surrounded by an emission nebula. The reddish glow surrounding the dark dust clouds of the horsehead is hydrogen gas ionized by the bright star Sigma Orion. Bright spots in the Horsehead Nebula's base are young stars just in the process of forming. (Brendan Hoffman/Getty Images) #

IC10 is an irregular galaxy in the constellation Cassiopeia. The galaxy is approximately 2.3 million light years from Earth, and about 5,000 light years across. (Bill Snyder) #

M13 in the constellation Hercules is approximately 25,000 light years from Earth. The diameter is about 145 light years. M13 consists of more than several hundred thousand stars. In the upper corner of this image is the galaxy NGC6207. (Bill Snyder) #

M27 - Dumbbell Nebula also known as NGC6853 is in the constellation Vulpecula. It is approximately 1,360 light years from Earth. The nebula can actually be seen with binoculars and amateur telescopes. M27 is composed of gas ejected from a dying star. Most of what remains of this star is the white dwarf at the center of the object. All the expanding gas and dust in this image was at one point inside the star. (Bill Snyder) #

M31 - This is a 13 panel mosaic of the Andromeda galaxy which is the closet galaxy to the Earth at 2.5 million light years (Bill Snyder) #

M42 is an emission and reflection nebula in the constellation Orion it is approximately 1,350 lights years from Earth and measures about 25 light years across. The Orion Nebula is an example of a stellar nursery where new stars are born. It can be found in the middle "star" in the sword of Orion, which are the three stars located beneath Orion's Belt.

M51 - Whirlpool Galaxy In the constellation Canes Venatici is approximately 25 million light years away. Another interacting galaxy in the image is NGC5195. M51's spiral structure was caused by NGC 5195 passing through the main disk of M51 about 500 to 600 million years ago. The companion galaxies are easily observed by amateur astronomers. The two galaxies may even be seen with binoculars. (Bill Snyder) #

M57, found in the constellation Lyra, is approximately 2,300 light years from earth. It was discovered in January 1779 by Antoine Darquier de Pellepoix. (Bill Snyder) #

M74 (also known as NGC 628) is a face-on spiral galaxy found in the constellation Pisces. It is about 32 million light-years away from Earth. (Bill Snyder) #
13
NGC 660 Polar ring Galaxy is approximately 20 million light years away found in the constellation Pisces. A Polar Ring Galaxy is a type of galaxy in which an outer ring of gas and stars rotates over the poles of the galaxy. A rare find, these galaxies have a substantial population of stars, gas, and dust orbiting in rings, perpendicular to the plane of the galactic disk. This may have been caused by capturing material from a passing galaxy. (Bill Snyder) #

NGC891 is a unbarred spiral galaxy in the constellation Andromeda, approximately 30 million light years from Earth. It was discovered by William Herschel on October 6, 1784. (Bill Snyder) #
15
NGC1333 Is a dark and dusty reflection nebula found in the constellation Perseus, approximately 1000 light years from Earth. In this dark and dusty nebula there is new star formation with most of the stars less than 1,000,000 years old. That's pretty young for a star, considering our sun is 4.5 billion years old. NGC spans about 6 light years across. (Bill Snyder) #

NGC 1579 resembles the better known Trifid Nebula, but lies much farther north in planet Earth's sky, in the constellation Perseus. (Bill Snyder) #
17
NGC5395, also known as Arp84 the Heron Galaxy is approximately 162 million light years away. NGC5394 is an interacting galaxy, believed to have cartwheeled through NGC 5395. (Bill Snyder) #

NGC7023 - the Iris Nebula - is a bright reflection nebula in the constellation Cepheus. It is aproxmatly1,300 light years away and 6 light years across. (Bill Snyder) #

NGC7635 - The Bubble Nebula is approximately 7,800 light years from Earth and measures about six light years in diameter. NGC7635 can be found in the constellation Cassiopeia. The powerful stellar winds from a Wolf-Rayet Star create the spherical bubble. A Wolf-Rayet Star is an unusually powerful star, discovered by astronomers Charles Wolf and Georges Rayet. This image is a Ha OII BiColor image. (Bill Snyder) #

Sh2-106 Hourglass Nebula is in the constellation Cygnus. It is approximately 2,000 light years away. This is a compact star forming region at only 1.6 light years across and two light years long. The newly-formed star called S106 IR at the center of this image is surrounded by dust. The high speed winds of about 200 km/s, due to the matter ejecting from this star, are responsible for the gas cloud's hourglass-like shape. (Bill Snyder) #

Sh2-115 is an emission nebula in the constellation Cygnus. It is approximately 7,500 light years away. This object is located about 2.5 degrees Northwest of the bright star Deneb. (Bill Snyder) #

The Cygnus Wall is in the southern area of NGC7000 also known as the North America Nebula. It is approximately 1,800 light years from Earth, and can be found in the constellation Cygnus. The Wall is an energized shock front and contains the most concentrated star formations in the nebula. (Bill Snyder) #
