Field notes
The workbench builds a spacing budget from the telescope’s rear reference plane toward the sensor, combining optical lengths, thread connections, reducer or Barlow factors, and optional filter correction. Its examples cover 640 mm APS-C, 360 mm square-sensor, and 1,400 mm full-frame setups. Users can import components from CSV, retain plans in the browser, or generate a link that exposes the entered inputs and source URLs.
