The Stars

Posted by Paul On April - 21 - 2013

On this page are pictures I've taken of the stars.

This is Capella taken on 4/5/2013 120 sec exposure at ISO 800

4/27/2013 This is a picture of Arturus, 4 minute exposure with ISO of 200.  I am now using my focal reducer which changes the telescope from an F10 to an F7 – that means the exposure time is cut in half.  That's a big advantage for astrophotography.
