Helix Nebula by Damian Peach
CDK700 (28″) @ F6.8. FLI camera. L: 90mins. RGB: 5mins.
One of the brightest planetary nebulae in the sky. It is located around 700 light years away and spans around 2.5 light years in size. Many background galaxies are visible in the image (which are vastly more distant) including some visible through the nebula itself.
Planetary nebulae such as this one represent the very late stages of low-medium mass stars (such as the Sun.) Indeed the Sun itself will one day create a planetary nebula perhaps similar to the Helix, billions of years from now.
Trifid Nebula (M20) by Damian Peach
CDK700 (28′) @ F6.8. FLI camera. L: 60mins. RGB: 15mins.
This famous object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent ‘gaps’ within the emission nebula that cause the trifurcated appearance) It is located around 5000 light years away.
IC 5148 by Damian Peach
CDK700 (28″) @F6.8. FLI camera. L:60mins. RGB: 5mins.
Nicknamed the Spare-tyre nebula,IC 5148 is a planetary nebula located around 1 degree west of Lambda Gruis in the constellation of Grus. Around 3000 light-years distant, it is expanding at a rate of 50 kilometres a second, one of the fastest expansion rates of all planetary nebulae.
The Grus Triplet by Damian Peach
CDK700 (28″) @ F6.8. FLI camera. L: 60mins. RGB: 5mins.
This group of galaxies is located in the southern constellation of Grus and consists of three close spiral galaxies – NGC 7582, 7590 and 7599 located around 60 million light years away. The field also contains hundreds of more distant galaxies, many of them over a billion lights years away
