Over there was a man rigging up a brand-new 14-inch PlaneWave CDK14 Corrected Dall-Kirkham telescope.
Andrew Robertson's drawing shown here was made from his home observatory near Bungay in Suffolk in 2010 July using a 30cm Dall-Kirkham telescope and 27mm Panoptic eyepiece, giving a magnification of x 135.
These Dall-Kirkham telescopes are available in 250-mm (3,990 [euro], US$5,111) and 315-mm (4,950 [euro], US$6,342) apertures.
