Overview:
Conceptus Celestia was a public ‘Star Party’ event organized by the Antariksh club of VI. Held on the 4th of April and extending into the morning of the 5th, the event took place at Chandavne nights camping, a secluded and dark location approximately 64 kilometers from Pune, ensuring minimal light pollution for optimal night sky observation. The event was a resounding success, enjoyed by 80 attendees who had the opportunity to observe constellations, deep sky objects, and participate in two insightful sessions led by Sir Jameer Manur and Pranav Pujari.
The first session, held before dinner while the moon was still visible, saw Jameer Sir enlightening the audience on the detailed history of constellations, methods for their identification, and techniques for using night sky patterns to determine polar directions and other geographical relationships. Following this, a doubt-clearing session with both Sir Jameer and Sir Pranav addressed queries about the night sky, stars, and deep sky objects, while also dispelling common myths linking astronomy and astrology. The second session, conducted after dinner and moonset, provided information on various calendar systems, the rationale behind the number of months in a year, and the connection of their names to corresponding constellations. With the moon now set, the audience was primed for observing the midnight sky.
