DPc's Current Observatory at Costa del Silencio, Tenerife

C-11 is ready for action from the current site. The balcony is about 6 metres up and faces SE, and is directly opposite (20 metres away) from a "rowdy" Scottish Bar - Karaoke evening there provides weekly observing "entertainment" for DPc. The silver tarp serves to keep the rain/sun at bay - which actually works very well.
