Steve Ringwood appraises the Orion Funscope Astro Dazzle, an eye-catching 4½-inch (114-mm) f/4.4 Newtonian reflector on a tabletop Dobsonian mount designed for beginners. The pre-assembled instrument possesses an inherent simplicity that will not challenge, with an aperture that brings a wealth of astronomy’s best to the viewer, he says.
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.
Steve Ringwood appraises the VMC110L, a novel “grab ‘n’ go” modified Cassegrain telescope of 110mm aperture and 1035mm focal length (f/9.4) from renowned Japanese manufacturer Vixen. The instrument features twin 1¼” eyepiece ports — one of which can be used for imaging or photography — and an internal flip mirror system to quickly switch between the two.
There is a delicious irony that ‘finding’ the brightest astronomical object in the sky is associated with the greatest danger — if one were to attempt using a conventional finder to point a suitably filtered telescope at the Sun, that is. Altair Astro’s Solar Finder permits simple, safe and swift alignment of your solar telescope, says reviewer Steve Ringwood.
Steve Ringwood reviews a dedicated 3″ field flattener designed for use with Orion’s EON 115/130 EDT refractors. One side of the field flattener threads on to the 3″ focuser, whilst the other offers a wide M48 thread that enables fixture of DSLRs, etc. without the vignetting possible with smaller M42 designs — particularly when deployed with full frame sensors.
Vixen has introduced a remarkable looking 7-element ocular that yields an expansive 83° apparent field. Yet the optical somersaults entailed in doing so are achieved without harm to the final image, yielding a stellar field with sharp edge-to-edge field definition with no vignetting – even on instruments of low focal ratio, says reviewer Steve Ringwood.
