Amazon’s "Deal of the Day" on the Celestron SkyScout, a GPS-enabled "personal planetarium," caught our attention – we reviewed (and loved) the device on Z Recommends last year, naming it a ZRecs Top Pick, and it got a mention on GeekDad as well. The "list price" of over $600 claimed on the sale page is ludicrous – we have seen it sold routinely for $400 – but $199 is a great deal any way you look at it, and a great choice for Father’s Day.
If you’d like to become an amateur astronomer at a lower price point, we love The Stars by H.A. Rey (yes, that H.A. Rey). It weighs a bit less, doesn’t require batteries, and is equally user-friendly; from its opening sentence, you know you’re in good hands: "This book is meant for people who want to know just enough about the stars to be able to go out at night and find the major constellations, for the mere pleasure of it." It stays pretty much true to its word.
