Manual Alt-azimuth Telescope
Navigate the sky confidently with Travel Scope 70’s intuitive pan handle. The alt-azimuth control with clutch allows you to point the telescope accurately and track celestial objects as they appear to move across the sky. Like a photographic tripod, you can move the clutch up/down or left/right to follow your object in the eyepiece.
Royal Observatory Greenwich Accessories Included
In addition to the 70mm refractor telescope, you will receive two eyepieces (20mm and 10mm), an 45° erect image diagonal, and a 5x24 finderscope. The two eyepieces offer different magnifications so you can view your subject at low or high power. The erect image diagonal allows for more comfortable viewing and right-side-up images. Lastly, the finderscope will help you locate objects and quickly center them in your telescope’s eyepiece.
Travel Backpack – Pack up your optical tube, tripod, eyepieces, and accessories safely and securely in the included custom backpack.
