Additional Information
Solar Warning
  • Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
  • Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
  • Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.

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.
