Astrophotography telescope package

$3,957.00 $3,495.00

Custom designed for astrophotography. An 8" Ritchey-Chretien Astrograph telescope plus a super-stable mount and accessories.

This telescope package is ideal for astrophotography. Choose from one of our many cameras - or mount your own DSLR camera to the back - and you are ready to go.


The telescope

Ritchey-Chretiens deliver images with very little distortion. They have a flat field of view, so objects are in sharp focus right to the edge of the image. The image is coma-free, so stars at the edge of the field of view remain perfectly round. And there is no false colour because they use only mirrors with no correcting lens. 

The 8" f/8 design provides enough aperture and a long enough focal length to give good image scale. It is ideal for smaller deep sky objects such as planetary nebulae, galaxies and small globular clusters. 

GSO mirrors are made from optical quality quartz 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. Each mirror is individually tested and hand-corrected if necessary after production, with final testing by laser interferometry.  

The open tube and quartz mirror enables the telescope to cool quickly, with virtually no problems with dew. A computer-optimised baffle system minimises any stray light in the tube.  


The mount

This CEM25P mount uses up to 60% less GOTO power consumption than other mounts in category.

The "Z" design mount puts the weight of the payload at the center of gravity allowing for greater natural stability. Given its payload capacity, this means the "Z" designed mount is unusually light. A nice benefit when setting up at a remote site. Other features include an adjustable counterweight bar to prevent obstruction with the tripod. And polar aligning is quick and accrate using the iPolar electronic polar scope.

The CEM25 is equipped with the latest advanced GOTONOVA GOTO technology, making it one of the most powerful and accurate GOTO mounts available. Its database includes over 59,000 objects. The Go2Nova Hand Controller is intuitive to use and its large 4-line LCD screen simplifies the process of setting telescopes and locating objects.
