Very confused about Eclipse Orchestrator.  When I set the aperture to 101mm and the focal length to 1080mm, it says, "Oh great, you're at f/101 then" and the script wizard sets really long exposures that I know will overexpose everything.  I'm assuming that if I use an 540mm telescope with a 2x powermate it doubles the focal length, right?

Sounds like your scope is an NP101is and 1080mm sounds like it won't leave much room for corona even with a full frame DSLR.  Below is a sample taken with an NP101is, a Canon 60Da, and a TV.8x FL reducer.  EFL is 435.

Apollo,

 

YOU SAVED ME!!!!  On your recommendation, I scrapped the Powermate idea and just used the TV101NPis with my 5DmkIII.  My tracking went off, and my totality photos were all off-center.  Had I used the Powermate, they would have all been lost due to the reduced field.  I can crop the ones I took and at least and have some decent totality photos.  Thanks again!

Always difficult to track the sun over a long period.  I found this out when I tried making solar flare animations so I used a Hinode solar guider to track the sun for the total eclipse.  It did an excellent job. Stopped working during my 1.75 minutes of totality and then turned right back on for third through fourth contact. (Handle's Seldom BTW)
