Joshua Tree National Park is an International Dark Sky Park, and the towns along Highway 62 sit far enough from Los Angeles light that the Milky Way is a naked eye object most of the year. These nights are run by people who track the moon phase for a living, which matters more than any piece of glass. Check the listing for what the moon is doing on your date.

The bright core of the Milky Way is up from roughly April through October, and it shows best on the nights around a new moon. A full moon washes it out no matter how clear the sky is. Operators book to the moon calendar, so the dates offered on a listing are already the good ones.
Colder than people expect, and the drop is fast once the sun is down. A twenty degree swing between afternoon and midnight is normal, and in winter it goes below freezing. Bring more layers than the daytime temperature suggests.
No. Every telescope night on this page brings the optics. If you want to shoot the sky yourself, look for the astrophotography listings, which are built around your camera and a tripod.
