About this opportunity
Khagol Mandal runs public overnight sky observation sessions at dark-sky sites outside Mumbai, where participants spend a full night watching planets, star clusters and nebulae through the group's telescopes.
Each session opens with an evening registration and an introduction to the telescopes, followed by a long first observation spell, a dinner break, an audio-visual talk with a question and answer round, and a second observation spell that runs until the early hours.
The volunteers who run the sessions are amateur astronomers, several with more than twenty-five years of observing experience, and they guide participants through constellation identification and deep sky objects. Sessions run from the Mumbai side are conducted in English with inputs in Marathi and Hindi, while the Nashik sessions are held mainly in Marathi.
Sessions fall on the Saturday closest to the new moon, about eight to ten times a year, and pause through the monsoon months. Seats are limited and booked in advance, with no entry at the gate. Participants sit on open ground through the night and are asked to bring a mattress, warm clothing and personal medicines.

Frequently asked questions
How often are the overnight sessions held?
Khagol Mandal holds about eight to ten public overnight sessions a year, on the Saturday closest to the new moon so that moonlight does not interfere with viewing. Sessions pause through the monsoon months from July to September.
Can a seat be booked at the venue on the day of the session?
No. Entry is by advance booking only and there is no spot entry. Seats are limited and each session closes once the booking capacity is reached.
