Diffraction Limited
Diffraction Limited sits at the point where imaging hardware and control software meet — MaxIm DL for acquisition, calibration and processing, alongside cameras and guiding hardware designed to work within it. For observers running automated sessions or contributing measurement data, that integration removes a great deal of friction. David Astro carries Diffraction Limited products in Canada, stocked in Canada and shipped worldwide.
Software and hardware choices interact here more than usual. Tell us what you image and how, and we will suggest a configuration.

The distinguishing feature is that the acquisition software, the cameras and the guiding hardware are developed with each other in mind.
- MaxIm DL: Acquisition, autoguiding, calibration, photometry and processing in one application, with a long history in both amateur and research use.
- Camera control breadth: Support for a wide range of cameras, filter wheels, focusers and mounts, not only the company's own hardware.
- Photometry and measurement tools: Built-in analysis for variable star work, exoplanet transits and astrometry, which is a substantial part of the software's user base.
- Cooled imaging cameras: Regulated cooling with mechanical shutters, suited to calibrated measurement programmes as well as aesthetic imaging.
- Guiding hardware: Guide cameras and self-guiding architectures designed to integrate directly with the acquisition software.
- Automation: Sequenced multi-target sessions with calibration and meridian flip handling, for unattended operation.
Why Choose David Astro for Diffraction Limited
Choosing acquisition software is a longer commitment than choosing a camera, so it is worth getting right.
- Workflow-based advice: We ask what you actually do — aesthetic imaging, photometry, remote operation — because the right configuration differs substantially between them.
- Hardware compatibility checked: We confirm your existing cameras, focusers and mount are supported before you commit to a software platform.
- Setup support: Help with driver configuration, guiding setup and calibration workflow after purchase.
- Authorized dealer: Genuine licences and hardware with full manufacturer support, handled domestically in Canada.
- Ships from Canada: No duties or brokerage fees for Canadian buyers.
Diffraction Limited in Canada — Frequently Asked Questions
- Is MaxIm DL suitable for a beginner?
- It is capable and deep rather than simple. Observers doing photometry or running automated sessions often find it worth the learning curve; someone taking their first images may prefer something lighter.
- Will it control my existing camera?
- It supports a wide range of hardware beyond the company's own. Tell us your camera, filter wheel, focuser and mount and we will confirm support before you buy.
- Can I do photometry with it?
- Yes, and that is one of its established strengths. It includes the measurement and astrometry tools needed for variable star and transit work.
- Does it handle meridian flips automatically?
- Sequenced automation including flips and calibration is supported, which is what makes unattended multi-target sessions practical.
