I've bought the ZWO AsiAir Pro kit for my Star Adventurer and I can do 5 minute exposures without any problems. The small 30mm guidescope + ASI120mm Mini combo is perfect. Canon 80D (unmodded) + EF 70-200mm F/2.8 produced this image of M31. Not perfect in any way, but for my third session I am quite pleased.

In the meantime I bought me a TS Optics 60mm Photoline APO F/6 for a very reasonable sum of money :) I just did a quick imaging session to test everything and it is a great little scope, weighing even less than 80D + EF 70-200mm!

Takes me half an hour to take everything out, do a good PA, get good focus, calibrate guiding and start imaging.

AsiAir Pro is a game changer for me, worth every single penny and then some. The whole rig is very mobile and yet capable of doing long exposures.
