Adrian Brown took the following image of the Eagle Nebula (M16) around 4 am on the 8th April 2007. This is a
single ten minute exposure through a 13nm hydrogen-alpha filter. It was taken with an ATIK ATK16HR camera through a Skywatcher 80ED Pro
refractor at f7.5. This was guided using an ATIK ATK-2HS camera through a Skywatcher 80T refractor. The set up was mounted on a Celestron CGE
mount. Some heavy blurring in Photoshop was needed to smooth out the noise in the image. Adrian also false coloured the image red in Photoshop
for effect. He comments: "Although my 80ED refractor could just peek over the observatory walls at M16, my 80T guidescope was partially
looking at the top of the observatory wall which led to rectangular guide stars. It still seemed to guide OK though!" |
