The ODK24Tr Truss Optimised Dall-Kirkham Telescope is our ultimate, pinnacle-tier 600mm (24-inch) observatory-grade instrument. Custom-engineered to order and precision-figured at our dedicated UK workshop, this massive flagship optical tube assembly (OTA) represents the absolute highest tier of optical engineering available today for professional scientific research, university observatories, and elite, uncompromised deep-sky imaging tracks.

Our custom telescope designs carry a prestigious heritage, trusted by world-renowned astronomical bodies including the ESO (European Southern Observatory) and ENO (European Northern Observatory). The ODK24Tr system is directly descended from our engineering architectures that have provided vital calibration and control data to support the massive main instruments at both the Paranal Observatory (Chile) and the Canary Islands. Deploying an ODK24Tr puts flight-proven, world-class tracking and imaging data right into your observatory dome.

At this scale, shortcuts are unacceptable. While other options on the market compromise with simpler 2-lens corrector systems to reduce assembly costs, the ODK24Tr features our integrated, multi-coated 3-lens system. Computer-optimized to guarantee a perfectly flat, wide field spanning well over 52mm, this extra lens element achieves breathtaking star profiles from the absolute center to the extreme edges of massive, modern large-format sensors. Experience pin-sharp, aberration-free tracking on faint nebulae, distant galaxies, and highly magnified planetary features.

Sustaining absolute focal precision for a massive 600mm mirror requires an flawless structural design. The ODK24Tr utilizes a state-of-the-art open carbon fibre sandwich truss framework. This advanced assembly ensures immense rigidity against mechanical flexure while offering a near-zero thermal expansion coefficient. As nighttime temperatures fluctuate across long-exposure runs, your focus positions remain locked down, completely eliminating the need for constant, automated refocusing interruptions.

The massive 600mm primary mirror is perfectly balanced within a custom honeycomb CNC-machined aluminium flotation cell, designed to eliminate mechanical stress and optical distortion. To clear boundary layer air currents and bring the large optical mass to ambient temperatures rapidly, the cell integrates 3 controllable cooling fans. Standard configurations include our specialized heavy-duty 3” CERES focuser, utilizing a 10:1 reduction Crayford system to deliver completely flexure-free operation under heavy equipment payloads.
