This is my first comet image taken from the ground. I am not yet able to track the camera correctly so i had to rely on star trails. Using the canon 450d , unmodified, I found this green sploch in the right place.image time aprox 90sec , date 20080804 08:30 pm local Oz east coast time.http://www.cometal.bigblog.com.au/js/editor/plugins/emotions/images/smiley-cool.gif

3日凌晨在南山观测到，目标明显，距离π Sgr很近。可惜未来得及做necessary estimate便被云层遮住。建议搜寻时不宜拿木星做跳板，不然会眼眩，建议直接用π Sgr做跳板。

要手跟彗星摄影，难度不小啊
