Royal Observatory Greenwich FirstScope 76 Celestron Telescope

From our astronomer here at Royal Observatory Greenwich:

"Telescopes are often slightly intimidating pieces of equipment, but models like this allow for a quick and straightforward setup. Everything necessary to start observing the night sky is included: star clusters, nebulae, planets, and of course the Moon are all potential targets (and even the Galilean moons in orbit around Jupiter, or making out the rings of Saturn).

With two eyepieces, you can quickly swap between a larger field of view or increased magnification, so even the same target can be observed in different ways. Additionally, its smaller size and weight makes the telescope suitable for children and convenient to move around: perfect for heading further afield to find the darkest skies!"

Dr Ed Bloomer is an astronomer and science communicator. Since joining Royal Observatory Greenwich, Ed has been involved in the full breadth of the organisation’s programming for all ages.

FirstScope’s Newtonian reflector optical system features a spherical glass mirror with a generous 76 mm of aperture. The FirstScope’s wide field-of-view provides bright, sharp views of the Moon’s mountains and craters in crisp detail. The telescope can also be enjoyed to pan the Milky Way, explore open star clusters, marvel at Saturn’s rings, or view favourite deep-sky objects like the Orion Nebula. 

FirstScope is the perfect companion for camping trips and all your outdoor sky watching adventures; a great choice for kids and families.

• 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.

The Royal Observatory Greenwich FirstScope 76 Celestron Telescope features a bespoke Royal Observatory Greenwich decorative design, celebrating nearly 350 years of scientific discovery at the Royal Observatory Greenwich.

The Royal Observatory Greenwich is the home of Greenwich Mean Time and the Prime Meridian, and one of the most important historic scientific sites in the world. Since its founding in 1675, Greenwich has been at the centre of the measurement of time and space.
