Geoptik

Mechanical Accessories and Transport

The range covers the connection between telescope and mount, and the protection between home and observing site.

• Tube rings: A broad range of inner diameters, including sizes that other manufacturers skip, with liners that protect tube finish.
• Dovetail bars and clamps: Vixen and Losmandy standard hardware in a range of lengths, machined to seat properly in a saddle.
• Padded transport bags: Shaped soft cases for optical tubes and mounts, which protect against handling damage at far less weight than hard cases.
• Counterweights: Weights in common shaft diameters, along with extension bars for balancing short heavy tubes.
• Camera adapters: Bayonet-to-thread adapters and prime focus hardware for attaching camera bodies to telescopes.
• Tripods and mounting hardware: Rigid bases and connecting hardware for mounts and instruments.

Why Choose David Astro for Geoptik

Mechanical accessories are a measurement problem, and a wrong measurement is a return.

• Ring size confirmed from your model: We look up your telescope's actual tube diameter rather than asking you to measure, since tube diameter and aperture are different numbers.
• Odd sizes covered: Geoptik's range includes diameters other manufacturers skip, which is often the answer for an older or less common tube.
• Transport advice: We will say when a padded bag is sufficient and when a hard case is genuinely needed, based on how your equipment travels.
• Authorized dealer: Genuine hardware with manufacturer warranty, in Canadian stock.
• Ships from Canada: No duties or brokerage fees for Canadian buyers.

Geoptik in Canada — Frequently Asked Questions

How do I know which ring size I need?

By the tube's outer diameter where the rings will clamp, not by aperture. Tell us the exact telescope model and we will confirm the correct size.

Are padded bags enough protection?

For careful car transport over short distances, generally yes, and they weigh far less than hard cases. For flying or rough handling, a hard case is the safer choice.

Will Geoptik counterweights fit my mount?

Only if the bore matches your mount's shaft diameter, which varies between manufacturers. Tell us the mount model and we will confirm before shipping.

Do you stock rings for older telescopes?

Often, since the range covers diameters that other manufacturers do not. Send us the model or a measurement and we will check.

Need a specific size?

Tell us your telescope model and we will confirm the ring or adapter. Ships from our Canadian warehouse.
