Usage
The Telescope can be used in the Observatory to spawn open the night sky that displays the constellations that correspond to the current amount of you have at the time of looking. This night sky is independent of the night sky formed from the large Observatory telescope, allowing the constellations to be activated a second time, or even an entirely different set of constellations if the count changed between the two views.
The Telescope can be used repeatedly to view the stars again as needed, but the constellations that appear are fixed from the first time the Telescope was used in a given Ovservatory.
If multiple Observatories are drafted in a day, the Telescope can be used in each of them to produce a new night sky for each.

The Telescope can be used in the Planetarium to permanently upgrade the room, unlocking a planet that confers permanent benefits to the room.
Doing this does not consume the Telescope, but only one upgrade can be done per day.
Spoilers Within
This section contains spoilers for all planetarium upgrades.
The planets seem to appear in a random order, except Mora which is always last. The effects of all unlocked planets apply. Once all five planets appear, the Telescope can no longer be used in the Planetarium.
