Spica Lunar Occultation - March 28, 2013

With my eastern low horizon getting obstructed by tall building, I went to fellow ALPer Alberto Lao's residence to observe with him the Spica Occultation event that will be visible on March 28, 2013. We observe at his residence's roof deck which has a clear eastern horizon. I set up my Canon EOS 500D DSLR with Canon EF100-400mm f.4.5-5.6 IS L Lens set at 400mm f/5.6 on Vixen Polarie Star Tracker. We were able to observe both Ingress and Egress event which happened at 20:49:30 (12:49:30 UT) and 21:53:08 (13:53:08 UT) respectively. With the need to overexposed the Full Moon to compensate on about 10 magnitude difference, I opted to do HDR composite image to maintain the Moon's lunar surface features. We were also joined by my astro kid son KC who won't missed a special astro event like this :)
