Terms of Use

Acceptance

By reading or otherwise using nightglass.shop, you agree to these terms. If you don't agree with any part of them, the simplest option is not to use the site.

What Nightglass is

Nightglass is an independent editorial journal about backyard astronomy — observing plans, ephemerides, and basic optics. It is not affiliated with any observatory, space agency, telescope manufacturer, or planetarium software company. Nothing on this site is sold, and no purchase is required to read any article.

Editorial content, not instruction

Articles here reflect personal observation and general reference research; they are shared for informational and editorial purposes. They are not a substitute for a dedicated instrument manual, a professional astronomer's guidance, or manufacturer safety instructions for any equipment you use — solar viewing in particular requires proper certified filters, and readers are responsible for following equipment safety guidance from the manufacturer.

Use of content

• You're welcome to read, link to, and share individual articles for personal, non-commercial purposes.
• Republishing full articles elsewhere, or presenting our writing as your own, isn't permitted without prior written permission.
• Short excerpts with clear attribution and a link back to the original page are fine.

No warranty

Astronomical timing, visibility estimates, and gear notes on this site are offered as general guidance based on typical conditions, not as guaranteed outcomes for your specific location or night. Actual results vary with local weather, horizon obstructions, and equipment. Nightglass makes no warranty, express or implied, about the accuracy or completeness of any content.

Limitation of liability

To the fullest extent permitted by law, Nightglass and its writers are not liable for any loss, damage, or missed observing opportunity arising from reliance on information published on this site.

The Nightlist app

References to Nightlist on this site describe a companion planning tool in ongoing development. Its availability, features, and release timeline may change, and inclusion on this site is not an offer of a finished product.

External links

Where an article links to an outside resource for further reading, that link is provided for convenience. Nightglass does not control, and is not responsible for, the content of external sites.

Changes to these terms

These terms may be updated from time to time; the current version is always the one posted on this page.
