67champ, one of our members just bought,(first lighted last Sat.), the LXD75 with a 6" Newtonian, Autostar. After correcting the error he/we made with the installed polar alignment scope, it tracked beautifully all nite. Views were V/G. All for $1504.00 delivered to your door.
The Tripod/mount is very substantial & stable, & it has mounting rings, so you can rotate the tube easily.
More choices.
