Hey Tom,

I don't believe you have the room in your dome for this, but I figure I'll
still present the idea.

What about having fixed light boxes, and moving the TOM's to point at the
light boxes when you want to take flats?  If you move the DEC limit switch
so when the optical tubes are level, you are just off the switch, you will
have a fairly repeatable location to move to.  RA can be controlled
accurately from it's limit, especially at slow speeds.  I have good
repeatability for ROB's level position on both axis.

I have hopes of doing this with ROB when I get his permanent home built, so
please don't say this is a bad idea ;-).

Cheers,
Rob

At the moment, I see no alternative but to use light box flats.  Possibly 
cloud flats will work.  This will be a pain for TOM2 and TOM3 since someone 
has to climb up inside the dome to attach the flat box to the lenses.  This 
is more than I can do.  Sigh!
