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.

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.

Comet 73/P Schwassmann-Wachmann17 viewsComet Schwassmann-Wachmann 3, one of the comets discovered by astronomers by Arnold Schwassmann and Arno Arthur Wachmann, working at the Hamburg Observatory in Bergedorf, Germany broke into fragments on its re-entry to the inner solar system, May 1, 2006, in a reaction triggered by the sun's heating the comet as it emerged from the frozen space of the outer solar system.

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.

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 Elephant Trunk Nebula High Resolution50 viewsThe Elephant's Trunk nebula is a concentration of interstellar gas and dust in the star cluster IC 1396 and ionized gas region located in the constellation Cepheus about 2,400 light years away from Earth[1]. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant Trunk nebula because of its appearance at visible wavelengths, where it is a dark patch with a bright, sinuous rim.

Melotte15 Inside The Heart Nebula61 viewsThe Heart Nebula, IC 1805, lies some 7500 light years away from Earth and is located in the Perseus arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula showing glowing gas and darker dust lanes. The nebula is formed by plasma of ionized hydrogen and free electrons.
The nebula's intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars known as Melotte 15 contains a few bright star

Jupiter Impact Animation From the 25th of July109 viewsHere is an animation of 12 Red channels ll taken with a C14" Lumenera SKYnyx 2-0 on the 25th of July the seeing was Ok. As you can see in the image the impact is clearly visible.A lot of work went into this image I must also say well done to Dave Gradwell for his great work on the Animation.

Jupiter RGB70 viewsHere is another image from the 15th that I did an experiment with.I processed and combined the RGB in MaxIm - dL V4.. I put in the RGB weight factors of the filters, did a planetary align and then some further processing in photoshop. I don't think it turned out to bad.
