Before you head outside
Three checks that matter in South Africa
Cloud and transparency
A target can be perfectly placed but invisible through cloud or poor transparency. Check the seven-night astronomy forecast before travelling.
Clear Sky IndicatorMoonlight
Bright clusters and planets tolerate moonlight better than faint galaxies and nebulae. Plan faint deep-sky sessions close to New Moon.
Moon & Darkness PlannerDew
Coastal and humid nights can fog corrector plates, objectives and eyepieces surprisingly quickly. Estimate the risk before setting up.
