Montures

Every experienced imager gives the same advice and most beginners discount it: buy the mount first. A modest telescope on a capable mount produces good images; an excellent telescope on an inadequate mount produces trailed stars and frustration. David Astro carries mounts in Canada — German equatorial, harmonic drive, alt-azimuth and observatory-class — shipping from Canadian inventory.

We size mounts against real imaging payloads rather than headline ratings, and we will recommend a larger mount when your setup genuinely needs one. Tell us your optic, camera and focal length.

What Separates a Good Mount from an Adequate One

Payload rating is the number on the box. The numbers that actually determine your results are periodic error, its smoothness, and the mount's stiffness under load.

  • Periodic error and its smoothness: A large but smooth error guides out easily; a small but jerky one does not. This is why two mounts with the same specification can perform very differently.
  • Payload margin for imaging: Load an imaging mount to roughly 50 to 60% of its visual rating. The remainder is the margin that keeps guiding stable in wind and at awkward angles.
  • Belt versus gear drive: Belt-driven mounts largely remove gear meshing error and backlash, which is why they have become the standard in mid-range imaging mounts.
  • Harmonic drive mounts: Strain-wave gearing carries very high payloads with little counterweight, trading some periodic error smoothness for extraordinary portability.
  • Encoders: Absolute or incremental encoders correct mechanical error in real time, reducing or eliminating the need for guiding at long focal lengths.
  • Focal length sensitivity: Guiding tolerance scales with image scale. A mount that is excellent at 500 mm may be marginal at 2000 mm with the same payload.

Why Choose David Astro for Mounts

A mount is the purchase people most often regret undersizing, and it is the most expensive one to correct later.

  • Sized to focal length, not just weight: We factor your imaging focal length into the recommendation, because guiding demands tighten sharply as image scale increases.
  • Cold-weather behaviour: We advise on lubrication, power supply sizing and the settings that keep a mount tracking reliably below minus 20.
  • Authorized dealer: Full manufacturer warranty and verified authenticity, with service and diagnostics performed in Canada.
  • Domestic shipping on heavy goods: Mounts ship from our Canadian warehouse, avoiding duties, brokerage fees and an extra freight handoff.
  • Setup support: Help with polar alignment, guiding configuration and firmware after the mount arrives.

Mounts in Canada — Frequently Asked Questions

How do I know if my mount is limiting me?
If your guiding RMS is a large fraction of your pixel scale, if stars trail at particular tube angles, or if you routinely discard subs, the mount is likely the constraint rather than the camera or optics.
Are encoders worth the cost?
At long focal lengths and for unattended operation, yes — they correct error faster than guiding can and remove dependence on a guide star. At short focal lengths, good guiding achieves most of the same result for far less.
Can a harmonic mount replace a heavy equatorial?
For most portable imaging, yes. They carry more per kilogram than any other design and set up in minutes. A high-end worm-gear mount still has an edge in raw tracking smoothness at long focal length.
What supply does my mount need in winter?
More current than the summer specification. Stiff grease raises draw, and voltage sag through a thin or long cable is the usual cause of cold-weather stalls. Size the supply and the cable together.

Buying the mount first?

Send us your optic, camera and focal length and we will size it properly. Ships from Canada with setup support.
