Activity 13 - Star Chart/Planisphere Results

Using your data from the navigation stars create a star chart. Rather than measure, to save time look up the RA and Dec of other major stars in the zodiacal and circumpolar constellations and add them to your chart.

1. Measure the distance between +90 degrees and 0 degrees on your graph. Cut a circle out of a second piece of paper twice that distance to give you a horizon for your Planisphere. Overlay it on top of your star chart with Polaris at the correct elevation for your site. Looking at an already assembled Planisphere can you find a combination of date and time that resembles your model?
2. If want to create a working Planisphere there is a link to a labeled star chart with five hundred stars in the Links section below.
3. See this site for pictured directions for making a star chart: https://www.wikihow.com/Make-and-Use-Star-Charts
