Thanks for the great review Jon!

I'm envious of the 102/Portamount combination - my ETX only takes about 10 minutes to set up but I'm so lazy these days that the thought of that 10 minutes of calibrate motors, training drives and aligning often prevents me from carrying the scope outside.

The options are a new setup like yours, or to get off my butt, guess I'll try the latter for now!

Duncan: I am basically a refractor/Newtonian guy. The AT-102ED is a nice companion for a larger scope like a 12.5 inch Newtonian. The AT-102ED on a ALT-AZ mount is sweet. The wide field of view is nice, it is capable of a 3.7 degree True Field of view so it does not need a finder, it's a 102mm Superfinder for Starhopping.

Still... your Etx-125, do you need to calibrate the motors everytime, with the one I had, it was only necessary to do that once. And while it doesn't enjoy the generous field of view that the AT-102ED does, you could use it without setting up the goto... Just a thought...

But yeah, a 4 inch refractor on an ALT-AZ mount: pick up scope and mount, open the door, walk though door to backyard, set scope down. You're done...
