The first day commenced with an introduction to the fundamentals of astronomy, laying a solid groundwork for the captivating journey ahead. Students delved into essential concepts such as stargazing techniques and telescope observation, immersing themselves in the profound mysteries of the night sky. Their inquisitiveness led them to explore the intricate aspects of telescope construction, including precise optical mirror placement, understanding focal length, aperture, magnification, and comprehending the f-stop ratio. With active participation, these budding astronomers meticulously measured the distances required for mirror and lens placement, methodically marking the telescope tube for subsequent installation. Concurrently, other students were engrossed in unraveling the enchanting secrets of the night sky, acquainting themselves with our position in the universe, captivating deep-sky objects such as nebulae and star clusters, and delving into the captivating narratives woven by constellations. To enhance their celestial exploration, a virtual planetarium was created utilizing a smart board and the Stellarium web app, empowering the students to independently navigate the vast expanse of the night sky and unravel its wonders. The afternoon session embraced an engaging quiz contest, stimulating friendly competition and fueling the students' enthusiasm for astronomical knowledge. The students wholeheartedly embraced the challenge, showcasing their understanding and passion for the subject.

The dawn of the second day marked the culmination of the telescope construction process. The students enthusiastically assembled the telescope mount, meticulously aligning and calibrating the mirrors and finder scope. Furthermore, their astronomical education continued with a captivating visual presentation on the lifecycle of stars, illuminating the captivating journey of stellar birth, evolution, and eventual demise.

Driven by their insatiable curiosity, a dedicated two-hour question-and-answer session ensued. The students eagerly sought knowledge, delving into diverse topics such as the timescale of our universe, Hubble's Law, the intriguing realm of relativity, and Newton's law of gravitation. Their relentless pursuit of knowledge exemplified their commitment to unraveling the mysteries that the cosmos holds.
With the completion of the telescope construction and enriching learning sessions, the pivotal moment arrived. Led to the terrace, the students proudly unveiled the telescopes they had meticulously crafted. As they peered through the eyepiece, their gaze directed toward the celestial realm, a profound sense of wonder enveloped them. The magnificence of celestial bodies unfolded before their eyes, leaving an indelible impression on their young minds.
