Optec Libra Alt-Azimuth Mount - Dovetail Adjustment Plate
Optec's new Libra Alt-Az adjustable mounting base allows easy adjustment in altitude and azimuth of guide scopes mounted to a Losmandy-style dovetail system. Unlike simple 2-axis stage adjusting systems that allow alignment of an imaging camera on a secondary scope, the Libra Alt-Az allows easy alignment of a secondary scope's optical axis to that of the primary.
"Why is it cool? Oh my... This is the only high-quality, high-precision device that allows dove-tail mounted guide-scopes or accessories to be collimated to a primary optical-system without the use of three-point rings." says Eric Blackhurst of OPT, "In other words, a user is able to move the smaller optical tube (relative to the larger) while using clamshell or tube-ring type mountings, as opposed to the traditional guide-rings that have been needed otherwise. This will significantly reduce the amount of differential-flexure in the smaller telescope’s mounting hardware, allowing for much longer sub-exposure lengths."
