About this PDF

Go beyond recognising objects in the night sky and learn to measure them: how far, how bright, and how certain your observations are. This illustrated Bengali guide builds on the Beginner edition through ten chapters covering sky measurements, the sky as a sphere, time and the moving sky, the Moon, planets, brightness, colour and distance, deep-sky observing, solar-observing safety, starlight and a capstone sky project. Clear explanations, worked demonstrations, step-by-step exercises and troubleshooting help readers put ideas into practice. A Working Reference explains technical terms in plain Bengali, while an Advanced Study Record helps readers track their observations and measurements. Suitable for readers who already understand basic observing safety, can use a simple sky chart, recognise the Moon's phases and keep an observing log. This is the Advanced edition, intended as a next step after the Beginner level.
