Altair Keystone Riser Block - Pair - GREEN
The Altair Keystone Riser Block let's you mount electronic accessories like an Mini PC, Pegasus Power Box, or dew controller underneath your telescope tube rings, by providing 60mm clearance between the dovetail plates.
The Keystone block is more than just a riser block. It allows you to attach telescopes and dovetail plates together to mount multiple telescopes around a rigid central "core" using Altair dovetail plates and is backward compatible with Altair Losmandy plates manufactured from 2008 onwards.
Made from CNC machined 6061 series aluminium alloy with a hard anodised surface finish. Block is 60mm Height x 100mm Width x 19.75mm Width.
The large centre hole allows you to pass a bundle of cables through the ends of your "block" construction.
The two centreline hole patterns are M6 ISO Metric Threaded with the 30mm hole spacing with the standard "Metric" Altair Refractor tube rings and Mounting plate hole pattern.
There are also an M6 40mm centre to centre hole pattern for Altair Guide Scope Rings, and of the M4 hole pattern for the Altair Finder Scope Dovetail Brackets, enabling you to mount a finder scope on any surface - side or top.
