Editorial Standards

1) Audience-fit first: We map every recommendation to a specific reader profile — experience level (true beginner vs. returning hobbyist), observing goal (planets, deep-sky, astrophotography), portability, storage, and home sky-quality (Bortle class).

2) Practical performance over headline specs: We weight optical quality, mount stability, and ease of first-night setup more heavily than aperture-on-paper. A 130 mm scope on a wobbly mount loses to a 102 mm scope on a steady mount in our scoring.

3) Scenario-based ranking: We rank by use case (best under $300, best for planets, best for kids, best for moonlit nights) rather than producing a single “winner” that fits no real reader.

4) Specification verification: Aperture, focal length, focal ratio, mount type, eyepiece set, and weight are verified against the manufacturer’s current product page before publishing or updating a recommendation.

5) Time-sensitive sky events: Peak dates, moon phases, opposition dates, and ring-tilt angles are cross-checked against NASA, the International Meteor Organization (IMO), the JPL Horizons ephemeris, the US Naval Observatory, EarthSky, and Royal Museums Greenwich. Discrepancies between sources are noted in-line on the page.

6) Update cadence: Event guides are reviewed within 7 days of the event. Buying guides are reviewed at minimum quarterly and whenever a featured product is discontinued or replaced.

Telescope Advisor is an independent editorial publication run by a small team of amateur astronomy enthusiasts. We are transparent about what is and is not first-hand testing:

• Hands-on observation: Several of the entry-level refractors we recommend (notably the Celestron AstroMaster 70AZ class and 70 mm travel scopes) have been observed through by team members on suburban Bortle 5–6 skies.
• Comparative analysis: Where we have not personally observed through a specific model, our ranking is built from manufacturer specifications, optical-design fundamentals (aperture, focal ratio, mount class), pricing, and a structured synthesis of independent reviews from Sky & Telescope, Astronomy magazine, Cloudy Nights forum threads, and verified user reviews. We say so explicitly when a recommendation is based on this method rather than direct observation.
• What we will not do: We do not invent fictional reviewers or fabricate observation reports. We do not present manufacturer marketing copy as independent testing.

If you have hands-on experience with a telescope we recommend — positive or negative — we want to hear it. Email support@telescopeadvisor.com.

For astronomy facts (peak dates, opposition dates, planetary positions, ring tilt, moon phase), we rely on primary sources:

• NASA Solar System Exploration and NASA/JPL Horizons ephemeris
• International Meteor Organization (IMO) shower calendar
• US Naval Observatory Astronomical Almanac
• IAU Meteor Data Center for shower designations and spelling conventions
• Royal Museums Greenwich and the Royal Astronomical Society for UK-relevant events
• EarthSky and Sky & Telescope for observing context

For product specifications, we rely on the manufacturer’s current product page. We do not source specs from retailer listings, which are often out of date or incorrect.

If we identify a factual error, we correct it promptly and update the “Last updated” timestamp on the affected page. Material corrections (changed peak date, changed product recommendation, corrected specification) are noted with a brief in-page correction line where the change is significant enough that a reader who saw the prior version should know.

Material corrections are prioritized on high-traffic and time-sensitive pages first.

To report a possible error: email support@telescopeadvisor.com with the page URL and a brief description. We aim to acknowledge within 3 business days and to publish a correction within 7 days where one is warranted.
