Comments  
The shots were acquired, dark framed and stacked using Astroart. The background was then smoothed in AIP4WIN, before returning to Astroart for a highpass filter and a low weight average pass. The exposures were guided using the piggyback Celestron scope and MX5C with a 2 x Barlow to give a focal length of 800mm at f/10 and a 2 second guiding interval.
