1m F/8 Ritchey Chrétien with dual Nasmyth Foci, Cape Town (South Africa)

Another large telescope for the South African Astronomical Observatory (SAAO). An 1m F/8 Alt-Az mounted Ritchey Chrétien for robotic use. It has dual Nasmyth Foci. The main telescopes used for research are located at the SAAO observing station (32°22.795’S 20°48,657’E) near Sutherland in the Northern Cape, a 4-hour drive from Cape Town.

Astronomy is our job

Observatory Telescopes

Big prime focus telescopes for private or public observatories including installation and full service.

Robotic / Remote

Robotic instruments for automatic imaging or telescopes for remote observation.

UVEX Spectrograph

Uvex Spectrograph

The UVEX is a “crossed” Czerny-Turner spectroscope optimized for wavelengths from near UV (<350nm) to near IR (1µm).

Diffraction Limited CCD Kameras

Aluma CCD 695 a

Our most popular camera, the SBIG Aluma AC4040 is a large format Scientific CMOS camera, featuring a 16.8 megapixel sensor with 9 micron pixels.  The camera is compatible with the StarChaser SC-4 Guider and optional AO-X Adaptive Optics accessories.

Diffraction Limited Overview

ASA Telescopes

ASA AZ1500 Ritchey-Chrétien Alt-Az telescope f6

ASA AZ1500 Ritchey-Chrétien Alt-Az telescope f6

An evolution milestone of high-end telescope systems with 1.5m aperture.

This complete solution represents a fully integrated alt-az observatory system. The AZ1500 1.5m is equipped with quartz optics from ASA. This guarantees diffraction-limited performance and best micro-roughness values even under the most perfect Earth-based astronomical seeing conditions. With fast focal ratio, the design results in less obstruction, higher contrast, and a more compact system. The size and cost of your dome infrastructure is reduced.
1500mm f6/f2 Ritchey-Chrétien Nasmyth Focus is equipped with absolute encoder secondary mirror focusing unit and configurable with up to 4 Nasmyth ports.
