Celestron has designed a very special initiation dobsonian telescope. The Firstcope is a unique 76mm aperture
Dobson (Newton) telescope designed and launched on the occasion of the
50th anniversary of man's arrival on
the Moon (1969-2019) .
It is an
initiation telescope , ideal for observing the Moon in detail, and highly recommended for young audiences, due to its easy handling. The optical tube is
76mm and the focal length is
300mm . The focal length is f / 3.95, a value that gives the telescope a lot of light. This model includes
2 eyepieces of 20mm (15X) and 4mm (75X).
It is a great option to be able to
transport it anywhere, even on a trip or on vacation to enjoy the clear summer nights. It can be used perfectly as a
desktop telescope. Robert Reeves , the inspiration for this model, first photographed the Moon in 1959, just as our space program was looking at lunar exploration. Since then, he has become one of the best lunar spectators in the world and a prolific author in astrophotography. Using Celestron telescopes from his Texas home, Robert captures more detailed images than professional astronomers during the heyday of Apollo missions.
