Follow-up observations by Hubble Space Telescope in 2005 separated the light of the slightly offset foreground star from the backgroundstar.
由哈勃空间望远镜担任的后续观测在2005年分离出了发自背景恒星、经过前方恒星时略有偏移的光线。

A major goal of the project is to capture gravitational microlensing events where an unseen body passes between a backgroundstar and Earth.
这一项目的主要目标是，捕获重力微引力透镜效应，看不见的星体在背景星和地球之间穿过。

Remarkably, the ion tail easily stretches past backgroundstar cluster NGC 1245 (upper left) in the constellation Perseus, about 1.5 degrees from the comet's lovely greenish head or coma.
