Thanks for your input guys I really appreciate it. Its good to see that other people have considered doing this to, I thought you might think What is this crazy guy doing.
So far I have been able to get very good images up to 30 sec with the standard base on the ground, but after that field rotation starts to come in. So for now I'll just have to stack lots of short exposures.
I'm using a Canon 350d EOS prime focus and I'm very happy with the results I'm getting but I would like to try A Cmos Or ccd imager in the future.
So for now I might just mount it flat on the pier as I can always change it later.
mswhin63 I would be very interested to see your set up with the modified drive when you get it going. Good on you for giving it a go. also how did you go with the alt-as operating as EQ as far as the controller goes? Clive
