This foto was taken with the camera attached to the SC, so I was working with 2000mm focal length.
I have used in other cases my camera with a 200mm lens mounted and I was able to do 300sec exposures with no guiding.
I think this mount is really capable to track once you have proper polar alignment. I use SharpCap Pro for polar alignment and I always try to get it to "excellent". In this case the deviation was 20".
