kaz under the skyジャック彗星 C/2014 E2 - 元・マスク・編集後画像


It's a really shy and thin tail. I initially thought there is no tail to this comet. But there is when I see the capture in gray scale with hard intensity. Then I have used this gray scale image as mask in image processing to give more power to the tail. It seems be working properly.
