GOTO Visual Telescope Package

A ready-to-go telescope package ideal for visual observing. An 8" Newtonian telescope plus a fully automatic GOTO mount and all the accessories you need. 


The telescope 

The classic reflector design that is simple, robust and easy to use. Newtonians give you a large aperture at an affordable price. High quality optics, a precise Crayford focuser, a rigid steel tube and short focal length make these telescopes ideal for astrophotography as well as visual observing. 

The Astronz-GSO 8" Newtonian has a 8 inch (200mm) primary mirror with a focal length of 800mm and a focal ratio of f/4. It gives clear, bright wide-field views of deep sky objects such as galaxies and nebulae. An 8 inch telescope will also show stunning views of the planets and the Moon. 

GSO mirrors are made from optical quality BK7 glass and are limited only by diffraction, which means they achieve the theoretical maximum resolution possible for the size of the mirror. They are machined and polished to better than 1/12 wavelength, sometimes 1/16 wavelength, which is considerably better than the industry norm.  

Apart from the quality of the optics, this telescope has a number of features that sets it apart. The steel tube gives much more stability than inferior aluminium models. The self-centering Crayford focuser gives more precise eyepiece alignment. And there is enough back focus that you can attach a standard DSLR camera for astrophotography. 

The mount

We call it "level and go", the term used to describe iOptron new AZ Mount Pro's simple set up routing. Using its built-in precision level indicator, the operator simply levels the mount and turns on the power; this capable computerized alt-azimuth telescope mount takes it from there. Utilizing the on board 32 channel GPS receiver and built-in position and angular detection sensors; the AZ mount Pro calculates its global position as well as the telescope orientation. Automatically the mount slews the instrument to an easily identifiable bright object in the night sky. The user need only confirm a bright object is in the center of the view, to activate tracking and GOTO functionality.
