March 2012 Meeting

Our March 2012 meeting "focused" on a continuing challenge for all imagers...getting great focus!

We covered both the mechanics and optics of focusing as well as attempted a live focusing demo with an artificial star (despite the fact we couldn't turn the room lights off!)

JOhn Davis gave a great presentation on automated focusing using FocusMax.

Also, we had some great images shared by APSIG members.

You can find a link to the meeting presentation here

Some of the focusing videos are included below.
