The A70Lf, although inexpensive, is not a toy telescope. Many amateurs begin with and enjoy countless hours under the stars with this instrument It has the same quality glass and exacting workmanship that goes into our much larger instruments. With this size aperture you will, as I did, be on your way to discovering the craters and mountains on our moon, the rings around Saturn and the storms on Jupiter. With a star chart you'll find beautiful double stars of varying colors, and on moonless nights, you will see the Andromeda Galaxy, The Orion Nebula and hundreds of other Deep Sky objects.
