Celestron Royal Observatory Greenwich Firstscope Table Top Telescope

Created in collaboration with the Royal Observatory Greenwich, this special edition Celestron FirstScope tabletop telescope brings a distinctive finish to a compact Newtonian reflector. Its 76mm aperture, 300mm focal length and Dobsonian mount make it a straightforward, portable choice for beginners, children and families looking for an accessible introduction to astronomy.

The wide-field optical tube is suited to relaxed observing from a table or other stable surface, with simple manual movement across the sky. Lunar features including craters and maria are highlighted on the tube artwork, while the supplied 20mm and 4mm eyepieces provide 15x and 75x magnification. Celestron Starry Night Basic Edition software, the SkyPortal app and a free PDF download of the Lunar Landscapes e-book by Robert Reeves are also included.

Safety information

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.
