## Description

Nightarc is a practical backyard astronomy primer for people learning to observe the night sky, with guidance designed to make getting started simple and approachable. Its free, no-account resource brings together seasonal sky-reading methods, binocular advice, a dark-adaptation checklist and an interactive magnification calculator. The guides explain how to use familiar star patterns to find landmarks such as Polaris, identify seasonal constellations and estimate distances with your hand at arm’s length. They also help readers compare binocular formats, understand magnification and exit pupil, set focus and choose suitable observing targets. The dark-adaptation checklist offers steps for preserving night vision, from using dim red light to allowing time for eyes to adjust. For telescope users, the calculator estimates magnification, exit pupil, true field of view and whether an eyepiece combination falls within a useful range. Nightarc also provides seasonal reference material and hand-measure guidance, helping observers plan a session and explore the sky with binoculars or a telescope. The site states that it uses no account and no tracking.
