February 2010 Meeting Pics

Jeff Barton gave an excellent presentation on Solar Imaging at the February APSIG meeting.


About 20 folks attended the talk at the Timberglen Library Branch, where Jeff not only showed some of his solar gear, but also gave a very informative slide presentation on imaging our closest star.


Jeff also demonstrated the use of Registax to process the solar images.

A big THANKS to Jeff Barton and all those who participated.

And another big THANKS to Andy Cheng for the photos!
