It really is a wonderful object though, and just goes to show just how easy Mike and other top class AP'ers (appear to) make it look when we gaze at their masterpiece renditions.

Hi Rob,
Yes, the limits of the 1000D has me currently eyeing off a modest DBK21 for imaging, to eliminate the need for coma corrector, mirror mods, low profile focuser and the extension tube for visual, as well as the dedicated astro cam aspect compared to the unmodded DSLR....
I dont want to go crazy with high end stuff until I get something more permanent in the back yard, but with the LP and the skyglow....I may have to look at finetuning everything to the point where lower ISO and LOOOOOOOONG subs are the way to go with some skillful processing to remove the unwanted stuff as travelling to dark skies is not only expensive, but a pain to lug everything around.
Plus, I often forget something small, like the last time I left my T ring at home and couldnt take ANY photos at all.....DOH.
Cheers
Chris
