SUMMARY:NRF|SAAO Cape Town Open Night
DESCRIPTION:Join us for Open Nights at the South African Astronomical Observatory (NRF/SAAO) in Cape Town\, held on the second and fourth Saturday of every month. \nEach evening begins with an engaging presentation on astronomy or a related field of science\, followed by a guided tour of the Observatory’s rich history—including our library\, museum\, and the historic 120-year-old McClean Telescope. \nWeather permitting\, guests will have the opportunity to enjoy stargazing through the McClean and additional smaller telescopes. \n\n\n\nGates open at 7:30 PM.\nFree entry for children aged 6 and under.\n\n\n\nPlease email cptbookings@saao.ac.za or call +27 21 447 0025 if you have any queries regarding bookings. \n\n\n\n\nSpeaker: Bhushan Joshi \n \nBio:  \nBhushan Joshi is a Scientific Officer at the Inter-University Centre for Astronomy and Astrophysics (IUCAA)\, Pune\, India. He is currently pursuing a PhD in Electronics at Stellenbosch University\, South Africa. \nOver the past 12 years\, he has gained extensive experience in the design and development of electronic systems for astronomical instrumentation\, with a particular focus on astronomical cameras. One of the latest cameras developed by his team for a solar telescope was launched aboard the Aditya-L1 mission and is currently operating at the L1 Lagrange point\, approximately 1.5 million kilometres from Earth\, continuously observing the Sun. \nAbstract: “Astronomical Cameras” \nFrom the hand-drawn sketches of the Moon and Jupiter’s moons by Galileo to today’s digital images of the night sky\, astronomy has always depended on how we capture light from the Universe.\nEarly astronomers observed the sky with their eyes and recorded what they saw by hand. This was later followed by the use of photographic plates and film cameras\, which enabled permanent recording of astronomical observations. Today\, electronic cameras have taken over this role\, allowing us to observe the cosmos with far greater detail and sensitivity.\n\nThis seminar introduces how astronomy cameras work and how they have evolved over time. It explains the basic principles of modern image sensors and compares everyday cameras with those used in astronomy. Although all these devices operate on the same fundamental principles\, astronomy cameras are designed very differently to detect extremely faint light and reveal objects far beyond what everyday cameras can capture.\n
