Thanks Betsy for posting my images. It makes all the hard work of producing these images seem worthwhile when others appreciate them too :)

M33 - Triangulum Galaxy

M33, also known as the Triangulum galaxy, has a diameter of about 50,000 light years. It is the third largest galaxy in the Local Group, a group of galaxies that also contains the Milky Way Galaxy and the Andromeda Galaxy, and it may be a gravitationally bound companion of the Andromeda Galaxy.

M45 - The Pleiades or Seven Sisters

Sailsbury (Dark sky site)

M45 is also known as the Pleiades or Seven Sisters. Unfortunately in this close up image the full seven are not visible. This is one of the closest star clusters to us, and is clearly visible to the naked eye as a 'cloudy patch' in the night sky. The cluster is dominated by hot blue stars which are lighting up the dust cloud they are passing through.

IC 1805 - Heart Nebula

This is a narrowband Hydrogen Alpha view of the very centre of the Heart Nebula. Click here for a wider view.

NGC 281 - Pacman Nebula in Hubble Palette

NGC 281 in Cassiopeia
69 x 15 minute exposures (17 hours and 15 minutes)
Approx. 6 hours per filter (SII, Ha, OIII)
Skywatcher 8" Newt / Atik 314L+
Hoo Peninsula (Fairly dark sky site)

This open star cluster with associated nebulosity, also known as the Pacman Nebula, is 10,000 light years away from us, and is in our very own Milky Way. This image uses the Hubble Palette, which is falsely coloured, to reveal more delicate structure than a true colour representation would.

M16 - Eagle Nebula

M16 in Serpens
5 x 15 minute exposures (75 minutes)

Hoo Peninsula (Fairly dark sky site)

M16, also known as the Eagle Nebula, is 6,500 light years away. This area of the sky was made famous by the Hubble photograph entitled 'The Pillars of Creation'. These so called pillars are approximately 57 trillion miles high, and get their name due to the new star formation that happens there. This image was taken with a narrowband Hydrogen Alpha filter.

M27 - Dumbbell Nebula

M27 in Vulpecula
6 x 15 minute exposures (90 minutes)
Skywatcher 8" Newt / Atik 314L+
Romney Marsh (Dark sky site)

M27, also known as the Dumbbell Nebula, is a planetary nebula about 1,300 light years away. This image was produced using narrowband Ha and an OIII filters, representing red and blue. From those a synthetic green channel was created to make a full colour image.

IC 1805 - Heart Nebula

IC 1805 in Cassiopeia

Chatham (Light polluted site)

IC 1805, also known as the Heart Nebula, is 7,500 light years away. This is an emission nebula showing glowing gas and darker dust lanes. The nebula is formed by plasma of ionized hydrogen and free electrons. This image was taken with a narrowband Hydrogen Alpha filter.

NGC 281 - Pacman Nebula

NGC 281 in Cassiopeia
20 x 20 minute exposures (6 hours and 40 minutes)

Chatham (Light polluted site)

This open star cluster with associated nebulosity, also known as the Pacman Nebula, is 10,000 light years away from us, and is in our very own Milky Way. This image was taken through a narrowband Hydrogen Alpha filter.

M101 - Pinwheel Galaxy

Romney Marsh (Dark sky site)

M101, also known as the Pinwheel Galaxy, is about 27 million light years away. With a diameter of 170,000 light years it is nearly twice the size of the Milky Way. It is thought that M101 underwent a near collision with another galaxy, and the associated gravitational tidal forces caused the asymmetry.

M51 - Whirlpool Galaxy

M51, also known as the Whirlpool Galaxy, is in fact two galaxies interacting with each other after a collision in the past. They are almost 25 million light years away from us.

M81 and M82 Galaxies

Full size image can be seen here : M81 and M82 with Canon 400D

M81 and M82 in Ursa Major

M81 (on the right) is a spiral galaxy that forms a pair with the irregular galaxy M82. The distance between the two galaxies is some 150,000 light years. M81 is the largest galaxy within in a group of 34, and is located 12 million light years away from planet Earth. This makes it one of the closet groups to the Local Group, which contains the Milky Way.

NGC 6888 - Crescent Nebula

NGC 6888 in Cygnus

Skywatcher 8" Newt / Canon 400D
Chatham (Light polluted site)

Also known as the Crescent Nebula, this object is 5,000 light years away. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 colliding with, and energizing, the slower moving wind ejected by the star when it became a red giant, around 400,000 years ago.

IC 5070 - Pelican Nebula

IC 5070 in Cygnus
11 x 20 minute exposures (3 hours 40 minutes)

Chatham (Light polluted site)

Also known as the Pelican Nebula, this is a large area of star formation and evolving gas clouds, located 1,800 light years away.

M13 Star Cluster

Published in Sky at Night Magazine, September 2009

This star cluster is 25,000 light years away from earth, and contains several hundred thousand stars, although some say up to 1 million. The age of M13 has been estimated to approximately 13 billion years.

Astro Photography by Arran Hill

Welcome to my blog!

I have been an astro photographer since May 2008, and I get out with my equipment whenever the weather allows.
Currently I am using a Canon 400D DSLR, and an Atik 314L+ astronomical CCD camera. These are used with my Skywatcher 200P 8" Newtonian Reflector, and my Williams Optics 72mm Refractor. All the equipment is on an EQ6 PRO mount.

I hope you enjoy my pictures, and please leave comments if you do!
