Hi, Alistair.
It's good to see your setup taking shape and I like your idea of keeping it light. This should help to overcome some of the torque problems I,m having with my drive.
I see you have the same output gear box that I'm using, at least it looks the same. As you have seen in my previous posts, I'm using direct friction drive onto the R.A wheel from this gear box, it's struggling with the weight! even though it's balanced. So as a consiquence, the geear box builds up torsion which gives me a 40 arc second wobble approximately every 2 minutes.
I'm just using a reostat to control it, but it's easy to over correct. As I said before, I wish I had your skills with electronics so I could use a stepper motor with computer control.
Still there's plenty I can do with a clean two minute track.
Here's a couple of images. 200mm f/6 prime focus.
Orion showing the error.
Tarantula a 2minute track, desregard bad focus or the slight wobble when taking a closer look, this was wind blowing the scope around.
Cheers,
Justin.
