Monthly breakfast at Eggberts?
Steve reminded us all that we have to be OUT of the library before 9 pm on our meeting nights. To help out with us always wanted to talk after meetings, he is proposing that we have breakfast on the nth Saturday of the month at 9 am at Eggberts. He is looking into reserving a large room Eggberts has on their west side for us to gather once a month for breakfast. Each person would pay for their own breakfast.

Daryl’s presentation on Stellarium:
Stellarium is a planetarium program actually used by many planetariums to run their projectors!
Download from stellarium.org. Latest version is 14.2
There are several versions out there to accommodate different computer platforms.
You can hook up a computer (with Stellarium on it) to a go-to telescope mount.
There are a number of controls at the bottom of the screen that you can use to select what you would like to view, such as constellation names, connecting lines, or fleshed-out characters.
You can change the field of view.
You can highlight an object and this will bring up a pop-up with all kinds of information on that object.
You can display parallax for an object.
You can select ocular view at top right and then edit the parameters to match your telescope or binoculars.
There are keyboard letter shortcuts you can use with Stellarium. For example, the letter L will increase speed.
If you click Jupiter, then O, you will get the orbital path of Jupiter.
The + key goes forward a day and – goes back a day.
Use Ctrl-up arrow to expand
You can see constellations as viewed and named by other cultures. (What we are familiar with would be “western” mode.)
You can simulate a lot of motions and conditions. You can use it to plan an observation session or go back in history to see what the stars looked like on a given night.
To print, use Print Screen
You can display the equatorial system of mapping celestial objects. Declination = latitude; Right angle = longitude.
You can save your settings on the main menu.
