Canon 350D Prime Focus

Can't find this explained on the forum. Can anybody help me out?

I understand that GS 10" Dob. 1250mm FL with 10mm EP = 125x mag.

If I attach a Canon EOS 350D at prime focus, what is the mag? (Without any barlows etc).

How does this work? (How do you calculate this)

Also, where would I buy a t-ring for the canon 350D in Sydney? What is a good price?

Finally, is the adapter from Andrews any good? I bought a 2x barlow but couldn't focus on anything, could only see the secondary mirror. Is this a problem with my scope.

Sorry for asking so many questions in one thread.
