Young learners often have misconceptions about how telescopes work and why it may take several months for a telescope to gather the photons for a picture. They will sometimes see space telescopes as able to take pictures of the entire sky since they aren't dealing with a day/night cycle or that the solar panels are futuristic warp drives that fly the telescope to different nebulas to look at up close.
With hands on tools that represent field of view and by extension magnification the learners will experience how telescopes and eye pieces change our view of the night sky. Part of the presentation will be the steps needed to construct your own set of tools in your home planetarium. Card stock and 3D printed versions of the tool will be compared and contrasted as well as instructional management techniques for working with the tools in the dark. Six different fields of view will be discussed and with four represented in the hands on tools the learners will use to observe the sky in the planetarium.
Presenter: Jack Northrup
Standard session time, non-workshop.
