Tele Vue-76: Imaging the skies from South Africa!

Our dear friend Vineet Bewtra in London, UK, has transported his trusty Tele Vue-76 APO refractor to Kagga Kamma Remote Observatory (KKRO) at the southern tip of South Africa, 180 km (110 miles) northeast of Cape Town. Located in a wilderness area known as the Cederberg, at 1200 meters (4000 ft) above sea level, the arid skies offer Bortle-1 seeing for astro imagers and views of wind-carved sandstone formations during the day.

This means all 110 Messier objects are on “either side” or “north” of the Sun and available for observation throughout the night — if an observer worked fast enough. Hence, the phrase “Messier Marathon” was invented to describe the all-night attempt.
