About this product

This special edition Royal Observatory Greenwich Travel Scope 70 is a great refractor telescope to start your astronomy journey. The telescope comes with a plethora of accessories, including but not limited to a sturdy tripod, Custom sized backpack and 2 different sized eyepieces. The setup of the telescope is easy and accessible and requires no tools to assemble. During the day the telescope can perform well as a far-reach spotting scope. However, during the night is where it really shines, with high-quality optics giving you the best views of all the night sky has to offer. This is all controlled with a manual tilt azimuth panhandle and an included clutch to make object tracking a breeze.  The two eyepieces offer differing magnifications for high and low-power viewing. There is a finderscope to identify target objects quickly and a 45-degree erect image diagonal to make sure you are always looking at right-side-up images.  

Comes with starry night planetarium software to make learning about the night sky accessible and fun for all.

Warranty: 2 Years

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.
