Adapter Plates

Adapter plates solve the problem of a mounting interface that does not match — a Vixen tube on a Losmandy saddle, a camera that needs a photographic thread on an astronomy dovetail, a guide scope that needs to sit higher than its bracket allows. They are simple parts that make otherwise incompatible equipment work together. David Astro carries adapter plates in Canada, in stock, with fast shipping across Canada and worldwide.

Rigidity is the thing to watch, since every plate adds a joint. Tell us what you are connecting and what it weighs and we will recommend something stiff enough.

Adapter Plates and Interface Conversion

Each plate converts one mounting standard to another, and each one adds a mechanical joint that must not flex under load.

  • Dovetail standard converters: Plates that let a Vixen bar mount in a Losmandy saddle or the reverse, without changing the telescope's existing hardware.
  • Photographic thread adapters: Convert astronomy dovetails to 1/4-20 or 3/8-16 for cameras, ball heads and photographic accessories.
  • Riser plates: Raise a guide scope or accessory clear of a dew shield or an obstruction while keeping the connection rigid.
  • Accessory mounting plates: Add attachment points to rings or dovetails for controllers, distributors and small equipment.
  • Side-by-side and dual mounting: Plates that carry two instruments with balance adjustment, common for a main telescope plus a wide-field camera.
  • Thickness and stiffness: A thin plate under a heavy load flexes at exactly the frequency guiding cannot correct, so mass matters here.

Why Choose David Astro for Adapter Plates

Adding a joint is always a rigidity decision, and sometimes the better answer is to avoid the adapter entirely.

  • Load assessed before recommending: If a plate would carry too much for its stiffness, we will suggest replacing the dovetail instead of adapting it.
  • Standards confirmed: We verify the dovetail types and thread standards on both sides before shipping.
  • Flexure diagnosis: If your stars elongate only when carrying a second instrument, the adapter plate is a likely cause and we will help confirm it.
  • Authorized dealer: Genuine hardware with manufacturer warranty, in Canadian stock.
  • Ships from Canada: No duties or brokerage fees for Canadian buyers.

Adapter Plates in Canada — Frequently Asked Questions

Will an adapter plate affect my guiding?
It can if it flexes under load. Every joint you add is a potential flex point, and thin plates carrying heavy telescopes are a common cause of unexplained star elongation.
Can I put a Vixen bar on a Losmandy saddle?
With an adapter plate or a dual-fit saddle, yes. Without one the narrow bar contacts only the edges of the wide clamp, which is not a secure grip for a heavy tube.
Is a side-by-side plate a good idea?
It works well within payload limits, and balance in both axes becomes more important. Keep the two instruments as close together as possible to minimize the moment arm.
How thick should a plate be?
Thicker than looks necessary, for imaging. Deflection scales sharply with thickness, so a modest increase in mass buys a large increase in stiffness.

Connecting mismatched hardware?
