1. I already have a low profile crayford on the dob and use a 35mm extension for visual focus. But I'm not paying for off axis guiding.
2. I have just moved to upgrade the cameras.
3. How long an exposure is too long for guiding though. 2 seconds?
4. I don't want to pay for guide rings. They are a rip off.
5. What is an xy guider?
6. I'll be neutered If I buy any more cameras.
I was looking at the bintel reducer :-
