夜空プラニスフィア スター・ファインダー - 小

I took this out during a camping trip and could actually identify constellations without squinting at my phone. The chart’s front/back design makes it easy to flip for different seasons without losing your spot.

The dial spins smoothly to match any date and time, which made finding Orion for tonight’s session embarrassingly easy. Took it out to a dark spot and the latitude markings lined up perfectly with what I was seeing overhead.

Set-up took me a minute, but once I aligned the date ring, the star positions for my latitude matched my backyard view perfectly. The card is more durable than a paper chart, so it survived a few drops on the patio.
