| This high
quality altazimuth refractor is an excellent choice for the
more serious beginning astronomer or terrestrial observer.
It's a powerful optical instrument with 131 times the light
gathering  ability
of the naked eye. This ability allows the FirstScope 90 AZ
to deliver images 78% brighter than those produced by a 60mm
refractor telescope. The objective lens is designed to yield
the finest images available in this class of optical instrument.
The accessories for this telescope are all made of glass with
metal construction, to ensure good image quality.
These telescopes have all glass components, coated optics
and smooth functioning mounts, with the added benefit of slow
motion controls on the mount for easy adjustments. The FirstScope
90 telescope tubes are glossy black aluminum.
The altazimuth mount is easy to use and
has slow motion controls on both the axes. These controls
are on flexible cables, to allow for quick and easy pointing
and tracking.
When used for astronomical viewing, this telescope yields
breathtaking views of the moon, Saturn with its ring structure,
Jupiter and its belts, and hundreds of deep-sky objects including:
galaxies, nebulae and star clusters. Add an optional solar
filter and you can observe activity on the sun. For terrestrial
use, you can enjoy views from your own backyard or take your
telescope out in the field to enjoy the natural environment,
up close.
