Cheers Louie, just a quicky.
Allan, it all seems to work pretty well, it's tracking well now, but I do get a few water drops at the doorway after rain so I might have to revisit the flashing around the door. I think the metal skin is catching water. I have a little awning hanging out above the door to stop this but it's obviously not good enough. I have the little FS60 and the Stellarview 60 guider in there on a SBS bar at the moment.
Greg, I got the bracket I made to fit pretty well on the FS60 but the motor I have is an old one and the drive shaft is thin and has a flat spot so it wouldn't fit the coupler
I think the newer motors are just a round rod looking at on line pics. I got some tubing to go over the shaft and now it fits. Maxim can see it and drive it but I need to see some stars to check it out further. Maybe tonight.
