Take the sky offline. Open the Sky mode menu and tap "Download the sky for offline use", pick a size, and the sky works with no connection. Search finds thousands more deep-sky objects: Sharpless, Barnard, van den Bergh, Abell and the cluster catalogues, plus names like the Lobster Claw Nebula. A result found by another name says so. The object you searched for gets a ring on the sky, and 80 more objects have a short description.
