Choosing a Base for Your Mount

Two numbers matter: how much the base deflects under load, and how quickly vibration damps out after a disturbance.

• Field tripods: Adjustable-height aluminium or steel legs for portable use. Adequate for most mounts, with rigidity improving substantially with leg diameter and shorter extension.
• Heavy-duty tripods: Larger-section legs for mounts above roughly 15 kg capacity, where a standard tripod becomes the limiting element in the system.
• Portable piers: A single rigid column instead of three legs, giving better stiffness and eliminating the tube-strikes-leg problem, at the cost of a heavier single item to carry.
• Permanent piers: Bolted or concreted installations for observatories, offering the best rigidity and a polar alignment that does not need repeating.
• Pier extensions: Raise the mount head to clear a long tube at the meridian, which is the standard fix for tripod leg collisions.
• Vibration suppression pads: Isolate legs from a deck or hard surface, cutting settle time noticeably on wooden platforms.

Why Choose David Astro for Tripods and Piers

The base is where people economize and then spend the season wondering why their stars are soft.

• Height calculated for meridian clearance: Give us your tube length and mount and we will work out whether your telescope will strike a leg crossing south.
• Rigidity matched to focal length: Settle time matters much more at 2000 mm than at 400 mm, and we size the base accordingly rather than to the mount's weight alone.
• Surface advice: We discuss what you are setting up on — deck, grass, concrete — because the ideal base differs, and a wooden deck often needs suppression pads regardless of tripod quality.
• Authorized dealer: Genuine products with manufacturer warranty, in Canadian stock.
• Domestic freight: Heavy items ship from Canada with no duties or brokerage fees for Canadian buyers.

Tripods and Piers in Canada — Frequently Asked Questions

How do I know my tripod is too light?

Tap the tube at high magnification and count how long the image takes to settle. More than two or three seconds indicates the base is the weak point, especially at long focal length.

Is a pier worth it for a backyard setup?

If you observe from the same spot regularly, very much so. Beyond rigidity, a permanent pier preserves polar alignment between sessions, which removes the longest step in setup.

Should tripod legs be extended fully?

No, if you can avoid it. Rigidity drops sharply with extension. Use the shortest height that still gives meridian clearance and comfortable eyepiece position.

Can I set up on a wooden deck?

You can, but decks flex and transmit footfall. Vibration suppression pads help substantially, and observing from ground level or a concrete pad is better where possible.
