Starscape over Tama River - Hoping to See More Beautiful One in the Rest of This Winter

It is already the midst of February, and this long winter is soon to welcome its end. But I haven't shooted nice starscape in the center of Tokyo this winter.

The sky is too bright, especially in the air near the ground. You can clearly see how bright the lower part of the sky is from the photo above. I think the air was quite transparent today, so transparent that it would have been pretty beautiful if I had been in Okutama, the west end of Tokyo. But this is the Tokyo. Perhaps I need some strong atmospheric depression which deprives the air of all the bad things to get satisfied...
