Well, it looks like the clouds are rolling back in for a bit, so I'll have to time to sort out some of these issues I think.
I'm sure the wife's going to be impressed that I'll be getting another scope already for this auto-guiding stuff.
A rough summary/list in no particular order:
1. Get Bahtinov Mask.
2. Sort out auto-guider gear.
3. Learn/setup APT. (Got an old netbook I'll setup to USB connect DSLR camera and run APT on for now to get started).
4. Motorised focuser.
5. Sort out focal reducer.
