Description

I finally got this!

This beautiful area took me about 3 months to capture. I start the whole session in January.

I have never reached such a long exposure time before! You can see that a lot of IFN are shown in this image. I think this image is the upper limit of my system. The aperture of the camera lens is too small(180mm F2.8, approximately 65mm aperture).
