The Leviathan of Parsonstown

31st Oct 2016

rosse-in-his-telescope2Halloween night being all about monsters, I spent it out in the dark thinking of a telescope big enough to be named after a monster – the Leviathan of Parsonstown – built in 1845 by Irish nobleman William Parsons, the third Earl of Rosse, who died 149 years ago, on this day.

With a 72-inch metal mirror weighing 3 tons and a tube 58 feet long, Lord Rosse’s Leviathan was the largest telescope in the world, a title it proudly

hcg90_hst_One of the joys of astronomy is taking a journey into the depths of space that pushes your eyes and equipment to their limits.

Stargazing with Antonín Bečvář

atlas-coeli-1Just when I thought that observing under these amazing Kalahari skies couldn’t get any better, it did.

Last night I got to use the most elegant star atlas of all – Antonín Bečvář’s Atlas Coeli 1950.0. It is simultaneously a work of art, a painstaking presentation of voluminous astronomical knowledge and a magnificent paean to the skies.

I’ve wanted this atlas for a long, long time, and it arrived yesterday in the mail
