The Owl Nebula -
The Owl Nebula, so named because of its resemblance to an owl with its two large eyes, lies in the constellation Ursa Major (Plough, Big Dipper). It is 1630 light years away.
This image was taken on 16 January 2013 using my FL102S refractor and Atik 314L+ CCD camera.
It consists of 2 hours worth of 10 minute subs with an Ha narrow band filter and 90 minutes with an OIII filter. These were calibrated, aligned and stacked in MaximDL. The two separate images were processed in Photoshop CS2 and then combined again in Maxim DL to produce a colour image.
