A little disappointed, we had a very bad winter here in all Chile, hope that next year it is better.

So very few images kept, I would do it again next year!

This image is made from a commercial observatory (Obstech) where I work and life, however I take advantage of the very good seeing and make my images for personally fun. my telescope is 5m from me among 25 others.
