乌鸦座η星在双筒中仍然可见,但完全想象不出ison的样子!

以下引自 CIOC:
=====
Comet ISON's brightness appears to be around two orders of magnitude brighter now, with reports of visual magnitude in the region of +5 to +6. For those with very dark skies, this now makes it a naked eye object, and even for those in urban environments it is readily visible as a fuzzy green blob about half an hour before sunrise in the south eastern skies.
=====
现在清醒多了,不会被“负多少多少等”再搞晕头脑了。至少在16号早上,想象中3等4等的ison是太过乐观了,一定要冷静。
不离夜晚会发光的城市远点……
目视?扯淡!
双筒?扯淡!
拍照?扯淡! |
