Hi Mike, sorry to say I can't make it, but, don't think you are under-gunned with your ED80. I've resolved Omega Centauri with 11X70 binos from a dark site. You are in for a treat at 90X with your ED80. Just be patient with it, let your eyes adjust, & Omega will 'POP' out.
You'll also resolve 47Tuc with your scope. Very different beadtie from Omega.
Another suggestion is drop your magnification as low as you can and slowly scan the sky. The ED80 is great for low power viewing and will reveal details that ate just too large for big apertures. Particularly the Milky Way with its mottled glow and dark nebulae.
Oh, and there is currently a mag 7 comet to chase down, Lovejoy. There's a write-up on it in the Observation Forum with maps to help hunt it down.
Alex.
