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.

February 2012 Meeting













The March 2012 meeting of APSIG ventured into new territory with a live videoconference presentation by Nightscape photographer Robert Arn.

Robert gave a great talk on his amazing nightscape techniques, and we gained some insight into how we might continue to bring in 'virtual' speakers in the future.










A good turnout for our long-distance presenter.  View Robert's amazing work at astroarn.com

Robert's presentation can be found here.


 
We also got the chance to express our thanks to APSIG Chair Emeritus JOhn Davis.  JOhn has spent many hours over the last couple of years establishing this group and creating a fantastic program.  Thanks JOhn!
