樓上的照片沒有用正規方法處理,影像水平低劣。我希望很快騰出時間,把這三年在西藏拍的照片正式處理出來....

Hi,
WeBo 1 is a strange planetary nebula (dying star) that was discovered in the mid-1900s. Although an interesting curiosity to astronomers (see the link below) no high-resolution color images have been taken of it... until now.
http://skycenter.arizona.edu/gallery/Nebulae/WeBo1It is a tiny, faint and very cool object. The discovers (that recognized its true nature) wrote a readable astronomical journal article about it here:

I just love the nearly perfect oval glow amidst a sea of stars and nebulae.
I hope your weekend was a good one.
Sincerely,
Adam
