With preassembled, adjustable stainless steel tripods, and quick release fork arms and tubes, NexStar SLT telescopes can be set up in a matter of minutes – with no tools required! You can see details of the lunar surface, Venus and its phases, polar caps on Mars, Jupiter and its four moons, Saturn with its rings plainly visible and much more! Most NexStar SLT’s can also be used as a land-based spotting telescope.

Powered by 8 AA (user supplied) batteries or an optional AC adapter (#18778) these NexStar GoTo’s love to travel.

Nexstar 90
Wednesday, 5 February 2014  | 

We bought the Nexstar 90 SLT telescope for my father in law. He's been after one for a long time. The telescope is small and light, so it was perfect for him, as he has a permanent back injury. He can carry it and set it up without any heavy loads or bending.

He's used the telescope every time there's a clear night, so we are really pleased we've managed to find one that meets all his needs.
