I just uploaded an image of M101 into the gallery. I captured this a couple of weeks ago. I have finally got my scope guiding properly (after a bit of a hardware upgrade
). I got a descent dove-tail plate. Its the Losmandy DM10
http://www.losmandy.com/secondary.html#DM. Its rock solid and doesn't flex when I mount my Skywatcher ED80 refractor on the Meade LX200. I use the Losmandy DR 125 ring set, to mount the ED80 on the dove-tail plate (found lower on the page of the above link). The ED80 is used as the guide scope at the moment with the Meade DSI Pro as the guide camera and the Canon 20d as the main camera.
So much fun...
