Allira Series™ of Equatorial Fork Mounted Telescopes

Telescope Accessory Mounting Systems.

The Anssen Technologies Telescope Accessory Mounting Systems are designed to enable simple initial mounting, quick release and easy balancing of accessories to the main telescope tube assembly. Accessories such as finderscopes, widefield cameras and off axis counterweights can easily be fitted and removed.

Simple initial set-up and fitting procedures.

Assembly and disassembly for portable instruments to be quick and hassle free, even in the dark.

Lightweight design to minimise flexure and overhang on the telescope.

High quality black anodised aluminium and non corrosive finishes on all surfaces. Stainless steel fasteners.

Can be purchased in a modular system depending on customer requirements.

High density nylon pads are fitted to the set screws to ensure no damage to the accessory instruments.

The Mounting System consists of three main component groups:

Support Ring Assembly

Intermediate Plate

Baseplate

Support Ring Assembly

The customer can choose any of three ring sizes available. The internal diameters measure 102mm, 134mm and 165mm. The sectional size and strength of the rings promotes extreme rigidity, even when supporting long instruments with substantial over hang. Three oversized stainless steel setscrews with positive feel locking knobs support the instrument being mounted.

The sliding base and locking assembly fitted to the ring enables positive clamping pressures to be applied. The clamp is a full 40mm long (not point contact).

Intermediate Plate

Two types of Intermediate Plates are available:

single dovetail (12mm thick, available in 305mm and 400mm lengths)

double dovetail (25mm thick, available in 305mm and 400mm lengths)

The Intermediate Plates enable the Ring Assembly to be positioned accurately with respect to the parent instrument. Each plate features large sectional area for rigidity and strength. Plate width is 60mm.

Baseplate

The Baseplate enables the Accessory System to be mounted to either an existing optical tube assembly, or a telescope mount.

The design promotes simple drilling and modification to fit to the parent instrument. Measures 75mm width by 200mm length. Positive clamping pressure along the entire length. Choice of large thumb knobs or Allen screws depending on customer requirements.
