Introduction to Telescope Use

COVID-19: Learn about our most up-to-date guidance for participants and leaders on our COVID-19 Response page. All participants and leaders must agree to the COVID-19 Code of Conduct before participating in this Mountaineers activity.
  • For Beginners (Getting Started Series)

Meet at the Seattle Program Center in Magnuson Park. The workshop will begin at 8:30pm in Cascade A and Cascade B. The workshop will run until 11:30pm.

Basic use of telescopes for visual astronomy

  • Limited to manual (non computerized, non-go-to) telescopes
  • Identify and understand the basic optics of the different designs of telescopes
  • Aligning and using a finder scope or equivalent pointing tool (such as a Telrad)
  • Use a telescope to find a target using an alt-az and an equatorial style mount
  • Know what polar alignment is, and be able to perform a coarse polar alignment
  • Slew to a target and achieve focus
  • Read a star-chart and use one to navigate to an object

Eyepieces and filters

  • Specifications of eyepieces, what they mean, which are important
  • How eyepieces interact with telescopes to provide different magnifications and
    fields of view
  • Limitations of optics
  • How to swap between different eyepieces in a dark situation
  • Choosing the best eyepiece for an object
  • Overview of useful visual filters
  • How to use visual filters

Care of optics

  • Proper handling of all gear
  • Preventing dust
  • Proper storage
  • Cleaning of optical surfaces
  • Collimation (Newtonians and SCTs only)
