Description

I have taken the shots in 2013.
I had planned to extend the exposuretime, but caused by always bad weather in October i decided to quit this Project and make the best of it as possible.

This was also the first time that i had used the CLS Filter.
The filter is causing really bad reflections between chip and filter what is leading to terrific halos around bright stars.
It also produces a green tint.

My choice was, leave the filter in the box.
