I wish I could say that I had it so accurately calculated but in the end I used Kentucky windage :-) Slewed the scope between the Sun and Venus using the GoTo, noting the point on the limb where it crossed (tada!). On the DFK41 mounted on the short tube 80 I went to Space Weather where they had the current solar image with the transit track overlaid, I then rotated the camera until the image matched. Good to go. Things are still looking good.

In fact, I have to thank my geometry teacher for nailing the ingress point on the Sun's limb. I was at an effective magnification of around 200x, and could only see about 30 degrees of the Sun's circumference. I started my camera rolling a couple minutes before first contact, and sure enough ... nailed it dead center.
