Tele Vue-NP101is Imaging Over Central Maryland!

A relative newcomer to deep sky imaging (2022), Doug Biernacki of Germantown, MD, is producing high-contrast images with subtle detail through his Tele Vue-NP101is, flat-field, visual/imaging, refractor using a ZWO ASI2600MC one-shot color, CMOS, APC-C format camera. An Optolong L-Ultimate 3 nm Dual Hα (656.3 nm) / OIII (500.7 nm) narrowband filter aids this setup by eliminating artificial and natural skyglow for maximum contrast. The resulting images are formed using the Hα-OIII-OIII (HOO) palette to map the red, green, and blue colors.

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. The shift from imaging at latitudes 52° North to 32° South has dramatically changed his astrophotography experience. This blog covers his journey through 84 degrees of latitude and provides a learning experience for others wishing to install a remote telescope.
