Description

Spring night was so gorgeous but so short.

This my first timid attempt to shoot all that beautiful dusts surrounding northern guiding star. And this image was also my first date with Pixinsight..

My future plan is improve my setup, shooting and processing skills and come back to this area next season.

Any suggestions, advices & constructive criticism are more than welcome. I really appreciate it!
