August 12, 2012 Jupiter-Moon Occultation

Last August 12, I, together with fellow ALP colleague Edgar Ang setup at the roof deck of Edgar's place to try to observe and document the Jupiter-Moon occultation that will be happening more or less around 2:43am for Jupiter to disappear behind the bright limb of the Moon (Ingress) and about 3:17am for Jupiter to reappear from the dark limb of the Moon (Egress). I was supposed to image the event at high resolution using Philips Toucam 740K webcam with 2x barlow on 8" f/10 Meade SCT and Canon EF 100-400mm f/4.5-5.6 IS L lens with EF 1.4x converter with Canon EOS 500D DSLR for full disk image of the event. Edgar, on the other hand, opted to just observe the event visually with a pair of 120x50mm binocular after seeing lots of clouds at the start of the event. Unfortunately, cloud cover is severe as it nears Ingress and I decided to let off of the high resolution imaging of the event and concentrated on full disk imaging of Ingress. Clouds didn't cooperate with us and we missed Ingress :( For consolation, we were able to observe Egress at around 3:16am. Despite the disappointment, we were still happy to be able to still get part of the event. Better luck next time for us :0
