SVBONY

The SVBONY Range and Where It Excels

SVBONY covers optics, cameras, filters and accessories. The strongest parts of the catalogue are the ones where a simple design is executed well rather than where complexity is attempted cheaply.

• SV503 ED refractors: FPL-51 doublets in 70, 80 and 102 mm with dual-speed focusers, widely used as first imaging telescopes and as companion scopes on larger rigs.
• SV550 apochromatic triplets: Three-element designs with better colour correction for imagers who want tighter stars and more focal length without moving to a premium brand.
• SV220 dual-band filter: A 7 nm Ha and OIII passband for one-shot colour cameras, and the single item in the range most often recommended without qualification for city imaging.
• Guide scopes and guide cameras: Compact 30 mm to 60 mm guide scopes with rigid clamshell mounting, paired with small sensitive guide cameras.
• Cooled colour cameras: Regulated thermoelectric cooling in one-shot colour formats, bringing calibrated deep-sky imaging within reach of a first serious setup.
• Eyepieces, zooms and accessories: Zoom and planetary eyepieces, field flatteners, dew heaters, red dot finders and adapters that fill out a rig.

Why Choose David Astro for SVBONY

A value brand rewards knowing which model to pick. That is most of what we add here.

• Candid model guidance: The range is uneven, and we will tell you where an SVBONY product matches something twice its tier and where you would be better served spending once on an alternative.
• Flattener spacing supplied: The SV503 refractors need a matched field flattener at a specific back-focus, and we provide the adapter and spacer list alongside the tube.
• Filter matched to your optics: A 7 nm dual-band performs well at moderate focal ratios and shifts off-band in very fast systems. We check yours before recommending it.
• Authorized dealer: Full manufacturer warranty and verified authenticity, with claims handled domestically rather than through international returns.
• Held in Canadian stock: Shipped from Canada with no duties or brokerage fees for Canadian buyers, and worldwide delivery available.

SVBONY in Canada — Frequently Asked Questions

Is SVBONY good enough for serious astrophotography?

For much of it, yes. The guide scopes, dual-band filter and ED refractors are genuinely capable, and integration time matters more than brand. The mount is where economising actually limits your results.

Does the SV503 need a field flattener?

For imaging with anything larger than a small sensor, yes. A doublet has a curved focal plane and corners will show elongated stars without one. Tell us your camera and we will specify the flattener and spacing.

Will the SV220 dual-band work with my telescope?

It performs well from about f/4 and slower with a one-shot colour camera. In faster systems the steep light cone shifts the passband off the emission lines and you lose signal. With a monochrome camera, use single-line filters instead.

Is warranty handled in Canada?

Yes. As an authorized dealer we process warranty and service claims here, so nothing has to cross a border or clear customs for support.
