Orion 60mm multi-use guidescope

These days, more is expected of a finder than to merely direct the main telescope to a celestial object of interest. This versatile 60mm f/4 instrument possesses a fine movement non-rotating helical focuser that has been designed to double as a traditional finder or guidescope with Orion’s StarShoot AutoGuiders, says reviewer Steve Ringwood.

Celestron Rowe-Ackermann Schmidt Astrograph

Celestron’s 280mm (11-inch) aperture f/2.2 Rowe-Ackermann Schmidt Astrograph (RASA) is capable of blisteringly fast photographic speeds, capturing images of nebulae and galaxies in seconds. An imaging system optimised for virtually any one-shot colour CCD or DSLR in existence, Ade Ashford appraises this photon-grabbing wonder in the context of evolving optical systems.
