Stn 44.n mag. 8.9/9; Sep1.7." This was a difficult object to 
locate and I only reached it with detailed maps of the area after a 20 minute hunt. 
 
Comments: The primary was a Whitish blue colour and the very close companion was White and of similar illumination.
 
Ambience: Two glorious Spring days resulted in a balmy evening, the 
air heavy with the scents of Freesias and Jasmine. A neighbour's 
light was a problem at first but as soon as I erected a tarp to block 
the light, it was switched off!  The Milky Way was high in the Western sky and my search for faint doubles in this area of sky resulted in stunning views of Globulars and Open Clusters of all shapes and sizes swimming into the field. Vega is peeking over the Northern horizon as I pack up.
