Alex I tried using a Cheshire for the first time maybe I've messed the collimation up a bit but it was quite windy I did dump a few subs because they were fuzzie and tracking was off. CALM were doing regular back burning too so there was some smoke haze about. When I was using DSLR Focus the results on the same star were all over the place.
