Spectroscopy Workshop (ASW2020)


Virtual AAVSO

Spectroscopy Workshop (ASW2020)


Our in-depth four-day online spectroscopy program directed by Ken Hudson (and based on his Sacramento Mountain Spectroscopy Workshop model with Joe Daglen) includes presentations by experienced amateur astronomers and professional astronomers. These presentations will teach you about the hardware and software used by amateurs and introduce you to the kinds of projects you can do as an amateur and how to contribute to pro / am collaborations. In addition, the professional astronomers speaking at ASW2020 will provide context and detail regarding the astrophysics of spectra and their own research projects. 

For 2020, this workshop has been formatted to fit your screen: therefore, it does not have a "hands-on" component, so you are not expected to own or use anything in order to participate. Attendees should note for their own pursuit of spectroscopy, however, that almost all software used by amateur spectroscopists runs on Microsoft Windows, as will most of the software demonstrated in this workshop. Some presentations will also use Python, which would potentially provide cross-platform support for Windows users. Attendees are not required, however, to have access to Windows.

**There are pre-requisites for this workshop. Please note them below before registering.**

 Workshop Pre-requisites 

Although attendees are not expected to know anything about astronomical spectroscopy:

  • attendees are expected to be comfortable with astronomical observing equipment commonly used by amateur astronomers. For example, attendees should have some experience with telescopes, mounts, astronomical cameras (CCD or CMOS) and the software used to control the hardware and produce images. (Don't worry if you don't have much experience--basic knowledge will suffice.
