I use TheSky with ASCOM on my Losmandy G11 all the time. As for why use
TheSky, the only reason is the automated plate-solving.

To connect multiple programs to a single mount you need an ASCOM Hub. For
the Losmandy ASCOM driver, it acts as a hub. I don't think the Meade does,
so you need to add one such as ASCOM's POTH (Plain Old Telescope Handset).

So: Download ASCOM, install Meade ASCOM driver, download ASCOM plugin for


Connect POTH to the Scope
Connect TheSky to POTH
Connect Guide to POTH

Unless I'm misreading the ASCOM website, it looks like you can make TheSky
use ASCOM via an intermediate layer...
