automatic image stacking
This summer we’ll be testing so-called “smart” telescopes, which incorporate a digital camera-style image sensor into a scope with a “go-to” automatic mount like the one used by our top pick. This combo allows for easier image capture for social sharing, and uses automatic image stacking to produce much clearer and more detailed shots of deep-sky objects than what you’d get from single long-exposure photos. This sort of telescope is usually paired with a mobile app that helps direct the telescope and provides information about the stellar objects you’re looking at.
