Corrections are genuinely welcome — especially on numbers. This is a static site, so the form below validates on your device and does not transmit anything.
What we can help with
Factual corrections to specifications, coordinates or formulae, with a source we can check.
Suggestions for equipment or articles that are missing, and reports of anything that renders badly in your browser.
We cannot answer individual equipment-purchase questions, diagnose a specific instrument, or provide observing predictions for a date and site.
Response expectations
This site is maintained on a volunteer basis. There is no support desk and no guaranteed response time. If you need a definite answer about your equipment, the manufacturer or your local astronomy society will serve you better.
