M20Lt10X240SecFinalPS_filtered.jpg

M-8 (NGC-6523) A large bright diffuse nebula and star cluster in Sagittarius. It lies 4500 light years from Earth and is 55 light years in dia. Image acquired on 8/6/2013.

M-20 (NGC-6514) A combination emission/reflection nebula located in Sagittarius, just north of M-8. It lies 4000 light years from Earth and is over 21  light years in diameter.

M27Lt10X240SecCopy.jpg

M-27 (NGC-6853) A large bright planetary nebula in Vulpecula. It lies 900 light years from Earth and is 2 light years in diameter. Commonly called the "Dumbbell".

M16Lt10X360Sec2_filtered Crop.jpg

M-16 (NGC-6611) A young open cluster surrounded by a large cloud of hydrogen gas, which is an area of intense star formation. The radiation from these very hot young stars is what causes the cloud of hydrogen to glow. Image acquired on 7/27/2019, an integration of ten 6 minute exposures.

HelixLt28X240SecStretch_filtered.jpg

The Helix Nebula (NGC-7293) This is the largest and closest of all the planetary nebulae, lying only 700 light years from earth. Visually it is almost half the size of the full moon (15 arc minutes) which at its distance translates

to an actual diameter of 1-3/4 light years. This image was

acquired on 8/18/2020.

M76Lt16X360Sec.jpg

M-76 (NGC-650/651) Planetary nebula in Perseus. It lies 2500 light years from Earth and is 1.5 light years in dia.

Image acquired on 9/17/2015.

Abell39Lt20X360Sec crop_filter2.jpg

ABELL 39 A large, dim planetary nebula in Hercules. It lies 6800 light years from Earth and is 5 light years in diameter. It central star is 15.5 magnitude. This image

acquired on July 20, 2017.

Eastern-Veil-PrairieFire copy.jpg

Eastern Arc of Veil Nebula (NGC-6992) This eastern arc of the Veil complex lies about 2.5 degrees NNE of the Western arc (NGC-6960, shown to the right). These two

arcs are remnants of a supernova that exploded over 45,000 years ago! They lie at a distance of 1500 light years from Earth. Image acquired on 7/29/2014.

M78Lt4X600SecCombinedNew_filtered.jpg

M-42 (NGC-1976) The "Great Nebula" in Orion. It forms the middle "star" in the Belt of Orion. This is a giant cloud of interstellar gas and dust, and is an area of intense star formation.

M17Lt10X90SecWeb2 copy_filtered.jpg

M-17 (NGC-6618) Commonly called the "Swan" or "Omega" nebula. Located near the Sagittarius/Serpens border. This is a huge cloud of ionized hydrogen gas that lies over 5,000 light years from Earth. This image acquired on 7/14/2012, is a 30 minute integration of 90 second exposures through the C-11 at f/2.

CocoonNebulaLt15X360Sec2.jpg

The Cocoon Nebula (IC-5146) A combination

emission & reflection nebula in northern Cygnus.

Image acquired on 8/3/2014.

NGC281Lt8X6min_filtered.jpg

NGC-281, The "Pac Man" Nebula. A large hydrogen emission nebula in Cassiopiea. It lies 9500 light years from Earth and is over 90 light years in diameter.

Image acquired on 9/18/2012.

BubbleNebula-Lt10X360Sec2_filtered.jpg

THE BUBBLE NEBULA (NGC-7635) A dim hydrogen emission nebula in Cassiopiea. It is illuminated by the intense

radiation from a super-hot Wolf/Rayet star (which can be seen at about 1 o'clock, inside the "bubble". Image acquired on 7/29/2014.

WesternVeil-10X360SecCopy2_filtered.jpg

Western Arc of Veil Nebula (NGC-6960) Located 2.5 deg.

SSW of the Eastern arc (NGC-6992, shown to the left) it is the remnant of a supernova that exploded over 45,000 years ago! It lies at a distance of 1500 light years from Earth. Image acquired on 7/29/2014.

ThorsHelmet2hoursLt copy_filtered.jpg

NGC-2359 "Thor's Helmet" A faint emission nebula in Canis Major

located 8 degrees NE of the star Sirius. It lies 11,000 light years from Earth. It is a large H-II (Ionized Hydrogen) cloud that is illuminated by a super-hot Wolf-Rayet type star.

M-78 (NGC-2068) A bright reflection nebula in Orion, located 2.3 degrees NE of Zeta Orionis (the easternmost

star in the "belt". It lies 1350 light years from Earth.

M1Lt8X360Sec.jpg

M-1 (NGC-1952) A supernova remnant in Taurus, only

1 degree NW of Zeta Tauri, the star that is the southern tip of the bull's horn. Discovered by Bevis in 1731.

NGC-7000, The "North American" Nebula. Located near the tail of Cygnus, the Swan, near the bright star Deneb. This is a vast cloud of gas and dust that lies 1600 light years from Earth.
