JR!! I do not know friend. These questions are far too technical for me... But if I get this info anywhere I will tell you. Wait I want to check something...

I just walked to the cupboard and checked. Yep, the 90 tilt shift has a hard stop. My 24 ts is out on rental so cant check but feel confident that it also has a hard stop. But f4 is not too good for stars...

Was Jupiter closer than infinity?

Canon's tilt-shift lenses have hard stops.

If it were we'd be in deep S___!

What lens are you using? I'd have thought Jupiter would be nothing more than a fuzzy little ball with anything less than a 4" reflector?

I find an easier, or, more accurate way to do focus for astro-pic's is to plug the 5D into the laptop. Then use live view on the laptop screen. It means I'm not bending my neck back and the image can be viewed larger. Sure, Jupiter works, but, Jupiter won't be around all year

As much as I want to do that it is not usually possible for me. I live in a city with pretty bright lights and the only way to do the astro is to get out of town and into the wilderness. There I struggle with setting everything up and am also hampered with Mosquitos and moths that get attracted by the light of the laptop.
