Nat Geo 70x900 scope

Quick delivery. Easy to set up. A bit too much plastic, but okay. Finish is good. View finder a bit cheap, but once set up as per instructions, it does it's job. Great terrestrial viewing with 20mm lens and with 12mm. Planetary viewing not too bad, managed to view Jupiter and its moons, Saturn and Mars, using the 12mm lens. Viewing of the planets was achieved shortly after sunset, and close to city lights, can't wait to use it in the Berg. Not badly priced for what you get. Will make great xmas gift.
