Myths, Symbols and Legends of Solar System Bodies

8 December 2015 Astronomy Now

The history of astronomy and how ancient peoples interpreted the Sun, Moon and planets through mythology, legends, art and popular culture is a fascinating one. However, reviewer I. Fontaine finds some serious errors in Rachel Alexander’s book. “It’s a rare example of reading something that overwhelms and disappoints in equal measure,” says Fontaine.

Howie Glatter Blug™

21 November 2015 Steve Ringwood

In order for a telescope to perform to theoretical limits its optical components must be perfectly aligned. With an optically fast Newtonian reflector this can be a challenge, but a laser collimator makes the task much easier. Steve Ringwood investigates Howie Glatter’s Blug™ — a charming contraction of ‘Barlowed collimation plug’.

Galactic Encounters

17 November 2015 Astronomy Now

“With many great photographs — from Edwin Hubble to the Hubble Space Telescope — a robust approach to the science which is (usually) very well explained, and detailed footnotes, this is a history of galactic astronomy that should definitely find space on your bookshelf,” says reviewer Andy Sawers.

Baader Polaris — measuring and guiding eyepiece

10 November 2015 Steve Ringwood

Reviewer Steve Ringwood takes a look through a versatile 25mm eyepiece from Baader Planetarium that has a field cross-hatched by an illuminated reticule that permits measurement through sub-divided etched lines. It can also usefully employed as a guiding eyepiece as it is fitted with a T-2 thread, plus 1.25″ and 2″ nosepiece adapters are available.

Orion EON 115mm ED triplet APO refractor

1 November 2015 Steve Ringwood

ED glasses are fast becoming ubiquitous in astronomical equipment, particularly in banishing the remnants of chromatic aberration of the classic refractor. Steve Ringwood takes a look at a 115mm (4.5″) f/7 air-spaced triplet from Orion in the USA. Designed for both visual use and astrophotography, it sports a beefy three-inch dual-speed Crayford focuser and comes supplied its own hard carry case.

Astro-Video Systems DSO-1 camera

20 October 2015 Ade Ashford

Are you looking for something to bring the wow factor back to your public viewing sessions, or a means to observe in comfort out of the cold? The sub-£100 Astro-Video Systems DSO-1 camera promises near realtime colour imaging of deep-sky objects and high-resolution planetary imaging with modest telescopes. Does it deliver? Ade Ashford finds out.

Geoptik CCD cooling fan

17 October 2015 Steve Ringwood

CCDs are incredible devices, gobbling photons that have travelled the vastness of space with great efficiency. Their Achilles heel is to also accept spurious signals from the immediate vicinity — within their own traitorous circuitry. Steve Ringwood investigates a CCD cooling chamber that will reduce a camera’s noise and increase its efficiency for both daytime and nocturnal imaging.

Equipment

Orion high-power 5× four-element Barlow lens

11 October 2015 Steve Ringwood

Reviewer Steve Ringwood waxes lyrical about this benevolent telescopic accessory — a new high-power 5x Barlow lens designed for 1.25-inch (31.7mm) eyepieces. It delivers a fairly ambitious amplification factor of five times to any ocular used with it, but its four-element design ensures that it does this whilst retaining image fidelity.
