My first attempt at the Prawn Nebula.
There is 3hrs and 20min of exposure time. 5 minute subs used. I'd started using iso400 but upped the ante to iso 800 later, but I tossed all of them in the pot to create the final image.
Darks and flats taken separately.
Scope - ed 80
Mount - heq5p4o
Guiding using qhy5
Camera Canon 20d
Software used ..... DeepSkyStacker and CS3
Imaged from a dark sky site on the 3rd and 4th of June 2010.
I repro'd this one again. This time putting the final image from cs3 through "Image Analyser". (does anyone else use this program?) Increasing local contrast and applying "Adaptive smoothing".
