Galileoscope Solar Kit
The team behind the Galileoscope telescope project is working with Explore Scientific to create a Galileoscope Solar Kit that includes a safe solar filter and sunshade. The Galileoscope is a wonderful telescope for observing solar eclipses – and for observing sunspots on any sunny day (and the Moon, planets, and […]
Continuous Solar Seeing Measurement System
Alcor-System has recently introduced a Continuous Solar Seeing Measurement System (CSSMS). The idea behind the CSSM is to measure the Sun’s scintillation and compute seeing figure equivalents. It can be combined with all of Alcor-System’s Sky cameras and nighttime seeing monitors. Turbulence (or seeing) is a great concern when recording […]
