I bought this to hold two scopes on my IEQ-45 in alt-az mode.
Unfortunately, my scopes combined are significantly heavier than the rating of the IEQ-45 PRO mount.
I might recommend not using this on a 7" Mak or 6" Refractor.
This is a well built device and mounts easily.
It can be adjusted to align the secondary scope with the "main" scope and holds that position well.
Accepts both Losmandy and Vixen style dovetails.
$188 (plus shipping) if purchased elsewhere.
