Ahhh, this night I really enjoyed myself! Imagine a unlikely place of beauty, the St. Croix lake, with the emerald waters of the “gorges du Verdon” and just above a sky of dream.
Between the two: the Olivier Planchon Observatory located near the nice small village of Bauduen. In the observatory a heavy reflector holding a main mirror of 24″ (620mm) f/d 3.3, a series of brand new Ethos eyepieces and voila.
My pencils show the target of the moment: another comet PanSTARRS, still quite small, but just near the comet a very pretty double star.
My friend “Apilaure” a specialist of double stars, talks about this double:
– It is also called STF1758, a Struve of 1830. The separation was 3.4” in 2010. It is more than likely a physical double because Hipparcos gives the same parallax for A and B, so a distance of 279 light year. The couple turns slowly, 15° in almost 2 centuries.
This is undoubtedly the superb material and this nice double, that I was deprived of the sight of the ion tail, I will return in this observatory, that’s more than sure!
I wish all the best to the ASOD community !
