NGC281 - The Pacman Nebula RGB56 viewsNGC 281 is an H II region in the constellation of Cassiopeia and part of the Perseus Spiral Arm. It includes or is near the open cluster IC 1590, the double star HD 5005, and several Bok globules. It is visible in amateur telescopes from dark sky locations. It is sometimes unofficially referred to as the Pacman Nebula owing to its fancied resemblance to the eponymous hero of the arcade game Pac-Man.

NGC 2841 - Galaxy in Ursa Major80 viewsNGC 2841 is an inclined unbarred spiral galaxy in the constellation Ursa Major. In 2001 the Hubble Space Telescope surveyed of the galaxy's Cepheid variables determined that it was approximately 14.1 megaparsecs or 46 million light years distant. (Thats around 276 million million million miles) Structurally, NGC 2841 is noted for its large population of young blue stars, and few star forming regions

NGC 2903 - Galaxy in Leo80 viewsNGC 2903 is a spiral galaxy similar to our own Milky Way Galaxy. Similarities include its general size and a central bar. Further investigation has indicated that current star formation is most rampant in a 2000 light-year wide circumnuclear ring surrounding NGC 2903's center. Astronomers hypothesize that the gravity of the central bar expedites star formation in this ring. NGC 2903 lies about 25 million light-years away and is visible with a small telescope towards the constellation of Leo.

NGC6888 - The Crescent Nebula in HA(R),G,B22 viewsThe Crescent Nebula (NGC 6888 or Caldwell 27) is an emission nebula in the Cygnus constellation, about 5000 light years away. 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 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward.

M13 - The Great Cluster In Hercules31 viewsThis was my first ever deep sky image taking on the 1 June 2006, Balbriggan Co.Dublin. David Grennan and Myself were testing My new 14" OTA with a 6.3 focal reducer at the time .
M13 was discovered by Edmond Halley in 1714, and catalogued by Charles Messier on June 1, 1764. M13 is about 145 light-years in diameter, and it is composed of several hundred thousand stars, the brightest of which is the variable star V11 with an apparent magnitude of 11.95. M13 is 25,100 light-years away from Earth.

M27 - The Dumbell Nebula25 viewsThis was taken on the same night as the M13 image on 1 June 2006,. This was a great night for me. Looking back at this image is funny even if it's not a master peace. It's when I started out in the world of Deep Sky imaging.

North America Milkyway56 viewsThis is the tip of Cygnus around the bright star Deneb or alpha cygnii which forms part of the summer triangle. It's an incredibly dense part of the cygnus spiral arm with stars too numerous to count. The north america nebula (NGC 7000) is outstanding here along with M39 and many dust lanes visible also.

M57 The Ring Nebula34 viewsThis is another The Sky at Night used for there programme image taken on July & August .Planetary nebulae are formed after medium or low mass stars, such as the Sun, exhaust their hydrogen fuel in the stellar core. At this point the structure of the star changes so it can achieve a new equilibrium condition in which it can continue to burn; the outer layers of the star expand and it becomes a red giant. Further internal temperature instabilities develop from the fusion reactions, causing the outer atmosphe

The Flame Nebula in Orion48 viewsThe flame nebula (NGC2024) is a glowing cloud of hydrogen gas where star formation is ongoing at 900-1500 light years away in the constellation Orion. Also visible is the horsehead nebula (IC434), both of which are difficult objects to observe due to their low surface brightness, and the proximity of one of Orion's eastern most belt star Alnitak.

Horsehead Nebula B33 - Close Up37 viewsThe Horsehead Nebula (also known as Barnard 33 in bright nebula IC 434) is a dark nebula in the constellation Orion. The nebula is located just below Alnitak, the star furthest left on Orion's Belt. The darkness of the Horsehead is caused mostly by thick dust, although the lower part of the Horsehead's neck casts a shadow to the left. Streams of gas leaving the nebula are funneled by a strong magnetic field.
