Hi all,

I attach a montage of the visual observations i made during my recent 
vacation in the Canary Islands. Conditions were good most nights, though 
hazy during the last 3 sessions due to winds from the Sahara.

I used an excellent  4" (10cm) f/10 Sovietski refractor for all 
observations at 200x - 240x, from the coastal town of Ten-Bel, Tenerife. 
The full data is attached as txt files.

Best Wishes

Damian
