Starlight Instruments

Starlight Instruments

Ask an experienced imager which single upgrade changed their results most and a surprising number will name a Feather Touch focuser. Starlight Instruments builds precision focusers and adapters in the United States, and their reputation rests on the same thing every time: a drawtube that holds several kilograms perfectly square and moves in repeatable microns. David Astro carries Starlight Instruments products in Canada, shipping from Canadian stock.

Most of that catalogue is adapters and telescope-specific mounting flanges, because Starlight designs retrofits for a very wide range of tubes. Tell us your telescope and we will identify the correct focuser and adapter combination rather than leaving you to decode a part number.

The Feather Touch System and Its Adapters

Starlight's approach is modular: a focuser body, a telescope-specific adapter that mounts it, and a set of drawtube terminations and motor options that adapt it to your workflow.

  • Feather Touch focusers: Dual-speed rack-and-pinion drawtubes with 10:1 fine focus, rated to hold heavy imaging trains without slip at any tube angle.
  • Telescope-specific adapters: Machined mounting plates for a very large range of refractors, Newtonians and Schmidt-Cassegrains, holding the focuser square to the optical axis.
  • Micro Focusers: Retrofit 10:1 reduction units that add fine focus to an existing stock focuser at a fraction of the cost of full replacement.
  • Drawtube terminations: Threaded end pieces that convert the focuser output to standard imaging threads, giving a clean, rigid base for the rest of the train.
  • Motor and controller options: Stepper drives and handsets that add absolute positioning and autofocus capability to a Feather Touch body.
  • Compression rings and clamps: Even radial clamping in place of single set screws, which removes both barrel marking and induced tilt.

Why Choose David Astro for Starlight Instruments

Starlight's catalogue is precise and dense with part numbers. Selecting from it correctly is most of the work.

  • Adapter identification: We match the focuser to your specific telescope's adapter, which is the step that most often goes wrong when ordering unassisted.
  • Focus travel checked: We verify that the replacement focuser's profile height still lets your telescope reach focus with your intended camera or diagonal.
  • Authorized dealer: Genuine Starlight Instruments products with full manufacturer warranty, handled inside Canada.
  • Held in Canadian stock: A deep on-hand selection, shipped domestically with no duties or brokerage fees for Canadian customers.
  • In-house service: Fitting advice, retrofit support and diagnostics after the sale.

Starlight Instruments in Canada — Frequently Asked Questions

Do I need the focuser or just the Micro Focuser?
If your stock focuser holds your load without slipping and you only want finer control, a Micro Focuser retrofit is the economical answer. If the drawtube slips or flexes under an imaging train, replace the focuser.
Will a Feather Touch fit my telescope?
Starlight makes adapters for a very wide range of tubes, including many discontinued models. Send us the make, model and drawtube diameter and we will confirm the exact adapter part.
Can I motorize a Feather Touch later?
Yes. The system is designed for it, and motor kits attach to the fine-focus shaft without replacing the body, so buying manual first and adding drive later is a reasonable path.
Is the warranty handled in Canada?
Yes. As an authorized dealer we handle warranty claims and service domestically, so nothing has to cross a border for support.

Fitting a Feather Touch?

Send us your telescope model and we will specify the focuser and adapter. Canadian stock, full warranty.
