Hi George. An EQ6 would handle that lot well enough. As a rough rule, the EQ6 has a capacity of 25kg but keeping the actualk load down to 2/3 to 3/4 would be good policy. The EQ6 tracks a lot better. It has a worm gear with about 50% more teeth than the usual 144 found in mounts like the LDX75, CG5 and the like and the motors also operate with a higher number of steps all of wich transpates into higher pointing accuracy.
The EQ6 also has a built-in ST4 port so your guide cam can talk direct to it (if it can). But more than that, the EQ6 works really well in pulse0guide mode with ASCOM and EQMOD. I control mine using a gamepad wirelessly. You can actually throw the Hand Control into the bottom drawer and leave it there.
It is possible to significantly im prove the performamnce of an LXD75 though. You could, for example, install a Warpsdrive kit that will take out a high proportion of the periodic errors in herent in the geared system Meade uses. I have both an EQ6 and an LXD75 and while I prefer the EQ6 for its capacity and features, I have been able to get the LXD75 to run quite well and image acceptably.
