Description

It was on top of my shooting list: the Helix Nebula

The night started very good. But I had to wait for the Helix Nebula because it is very very low...
Unfortunately clouds arrived quickly so I had to stop shooting...

Hope for this night again... forecast looks good... like today.... :-(
