What's worth looking at tonight, and how to find it
Session planning, deep-sky targets and the sky events actually worth setting an alarm for — organized by what you're trying to do, not by when we published it.
Session Planning
What's up, whether the sky will cooperate, and what to actually point at once you're out there.
PlanningBest Astronomy Apps for Beginners (2026)
The five apps that cover sky identification, weather, framing and light pollution — between them, nearly everything a night's planning requires.
Target CatalogA Field Guide to the Messier Catalog
110 objects, organized by how forgiving they are to find — the reference list to actually work from.
Planetary Observing
Setting expectations for what a telescope actually shows you, before disappointment does it for you.
Deep-Sky Targets
Individual object spotlights — what each one is, and how to actually find it. ORIVON Sightline tracks which of these are best this month.
