Miscellaneous Mount Accessories

Mounts arrive complete in the sense that they work, and incomplete in the sense that most setups need something the box did not contain — a hand controller holder, a levelling aid, an azimuth adjuster, a way to attach a power distributor without cable-tying it to a leg. David Astro carries miscellaneous mount accessories in Canada, in stock and shipped from our Canadian warehouse.

These parts are mount-specific and rarely well documented. Tell us the mount and what you are trying to add and we will identify the part.

The Parts That Finish a Mount Setup

Small conveniences that reduce setup time and the number of things that can go wrong in the dark.

  • Hand controller holders: Brackets that keep the controller accessible and off the ground, and stop the cable dangling into the mount's swing path.
  • Levelling aids: Bubble levels and adjustable feet, which matter because an unlevel mount complicates polar alignment and GoTo accuracy.
  • Azimuth and altitude adjusters: Replacement or upgraded fine adjusters for mounts whose stock hardware is coarse or awkward to reach.
  • Accessory trays: Tripod trays that hold eyepieces and tools, and add rigidity by bracing the legs.
  • Equipment platforms: Shelves and brackets for power distributors, controllers and battery packs, keeping weight off the mount head.
  • Anti-vibration pads: Isolate tripod feet from hard surfaces, cutting settle time noticeably on decks and concrete.

Why Choose David Astro for Mount Accessories

Most of these purchases start with a frustration rather than a product name.

  • Problem-first identification: Describe what is annoying you about your setup and we will name the part, which is faster than browsing a category.
  • Mount-specific fitment: Adjusters, trays and holders are model-specific, and we confirm the fit before shipping.
  • Weight placement advice: We recommend hanging accessories from the tripod or pier rather than the mount head, since weight above the axes counts against payload.
  • Authorized dealer: Genuine parts with manufacturer warranty, in Canadian stock.
  • Ships from Canada: No duties or brokerage fees for Canadian buyers.

Mount Accessories in Canada — Frequently Asked Questions

Does levelling the mount matter?
For polar alignment and GoTo accuracy, yes. An unlevel base makes the alignment routine less reliable and can leave residual pointing error even after a good star alignment.
Where should I mount a power distributor?
On the tripod or pier rather than the mount head. Weight above the axes counts against payload capacity, and cables that move with the mount are more likely to snag.
Do anti-vibration pads actually help?
On hard surfaces and wooden decks, noticeably. They shorten the time an image takes to settle after focusing, which matters most at high magnification.
Can I upgrade my mount's altitude adjuster?
On several common mounts, yes, and it makes polar alignment considerably less frustrating. Tell us the model and we will check what is available.
