IC 1805 - Heart Nebula

IC 1805 Heart Nebula by Arran Hill

Full size image can be seen here : Heart Nebula with Atik 314L+

IC 1805 in Cassiopeia
26 x 15 minute exposures (6 hours 30 minutes)

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 Pacman Nebula by Arran Hill

Full size image can be seen here : Pacman Nebula with Atik 314L+

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 Eagle Nebula by Arran Hill

M16 in Serpens
5 x 15 minute exposures (75 minutes)
Skywatcher 8" Newt / Atik 314L+
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 Dumbbell Nebula by Arran Hill

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 Heart Nebula by Arran Hill

Full size image can be seen here : Heart Nebula with Canon 400D

IC 1805 in Cassiopeia
21 x 20 minute exposures (7 hours)
WIlliams Optics 72mm Refractor / Canon 400D
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.
