I have just started using the Star Adventurer and can confirm the very good impressions mention above. I have sunk 3 wooden pegs into the lawn such that the mount is polar aligned when placed on them .( a quick check with the finder on the pole star position is very easy) I hang a building brick under the tripod for added stability. So far I have managed up to 6 minutes tracking without any trailing, but usually use shorter time exposures.
My only problem is finding and pointing the camera at the chosen target. The Canon 600D has a flip out screen which helps to centre a bright star, but does not show faint objects so that I am making repeated trips to my shed (heated !) to see if I have the image on the computer screen. Is there any way of mounting some form of right angled finder on the camera. Focusing a DSLR is a bit of a trial and error and not as easy as with a telescope focuser.
