Seeing & Transparency: How to Measure and Document

By John Johnson




Summary:

Many of the Astronomical League observing awards require you to observe, quantify, and document the atmospheric conditions called “seeing” and “transparency” when you are documenting your observations of the various celestial objects.  John will explain each term and provide examples on how to document them in your observing logs.  Various “measurement scales” for annotating your observations will be introduced and discussed..
