    Great viewing

    This telescope packs an unexpected punch. Crisp viewing in day or night. Outfitted with a 2″ 7mm/110 degree APM eyepiece, this lightweight, grab-and-go telescope does not disappoint when observing the sun in white light (my primary use) or taking in both planetary and deep space objects.

    Powerful Telescope!

    Portability and power were what I was looking for, this telescope doesn't disappoint. I like the fact that it can be upgraded later if I wish.
