Mount Types and What Each One Is For

Choose by what you do, not by capacity alone. A mount that is excellent for visual observing can be poor for long-exposure imaging, and vice versa.

• German equatorial mounts: The standard for deep-sky imaging. One motor tracks the sky once polar aligned, and periodic error correction plus autoguiding delivers minutes-long sub-exposures.
• Harmonic drive mounts: Strain-wave gearing carries heavy payloads with little or no counterweight, making a capable imaging mount portable enough to carry in one hand.
• Alt-azimuth mounts: Intuitive up-down, left-right motion, ideal for visual observing and grab-and-go use; field rotation limits unguided imaging without a wedge.
• Star trackers: Compact tracking platforms for a camera and lens, the lightest practical route into wide-field astrophotography.
• Tripods and piers: Rigidity below the mount matters as much as the mount head; a pier removes tripod flex and settles vibration faster.
• Counterweights and shafts: Correct balance reduces motor load and improves guiding, and extension bars help balance short, heavy optics.

Why Choose David Astro for Mounts and Tripods

Mounts are heavy, expensive and awkward to return. Getting the specification right the first time is worth more than a discount.

• Realistic payload sizing: We recommend loading an imaging mount to roughly 50 to 60% of its visual rating, and we will say so even when it points you to a larger mount.
• Pier and tripod height planning: We calculate the height you need to clear your tube at the meridian without striking the tripod legs, which is a common and frustrating surprise.
• Authorized dealer: Full manufacturer warranty, handled domestically in Canada rather than through international shipping.
• Canadian inventory: Heavy items shipped from within Canada, avoiding duties, brokerage fees and cross-border freight damage risk.
• In-house service: Diagnostics and repair for mount electronics and drives, so downtime is measured in days rather than months.

Mounts and Tripods in Canada — Frequently Asked Questions

How much payload capacity do I really need?

For imaging, plan on using no more than 50 to 60% of the manufacturer's visual rating. A 20 kg mount is comfortable with a 10 to 12 kg imaging payload including camera, guider, cables and dovetail.

Are harmonic drive mounts good for long exposures?

Yes, with guiding. They have higher periodic error than a well-made worm-gear mount but it is smooth and correctable, and their portability and payload-to-weight ratio are unmatched.

Do I need a pier instead of a tripod?

Only if you have a permanent site or you are seeing vibration settle slowly. A pier improves rigidity and repeatability of polar alignment but sacrifices portability entirely.

How is a heavy mount shipped?

From our Canadian warehouse, with no customs handling for domestic orders. We advise on freight for the largest mounts and piers before you place the order.
