As far as I know the LXD75 has no guiding port and is not a very stable mount. When I grabed a scope mounted on an LXD75 it wobbled all over the show (from the mount head not tripod or other areas
).
I'm looking at getting into some astro imaging and have been researching a good setup for a while. I'm going to start with a HEQ5 Pro GOTO mount and eventually add a 6or8" f5 newt (or meade schmit-newt) for deepspace.
But thats just me......
Good luck
Dave.
