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 chose Vega in the constellation of Lyra as my first sketch study, as it was the brightest star in my visible night sky (… and 3rd brightest star in the Northern hemisphere night sky after Sirius and Arcturus). I threw the towel in on several sketches before arriving to this one. It sure is different to sketch in the dark! My first attempts had severely mis-plotted star fields, and even though a sketch of the night sky is never 100% perfect, it wasn’t even looking close to what I was seeing in my field of view! An hour and a half later, I was satisfied enough to call this one my first.
I was able to spot the famous “double double” stars of Epsilon Lyrae very easily, as well as a light blue tint to Vega, and some various stars with a light tint of orange. Even though winter is coming along, I could still see part of the “Summer Triangle” asterism with Altair and Deneb.
Object: Vega in constellation Lyra
Date: November 15th, 2013 – 6:30 – 7pm CT

Conditions: 62°F, Clear
Instruments: 10×50 Wide-Angle Binoculars

(see the original sketch)
Object Name: The Moon and Beta Scorpius
Object Type: The Moon and a double star
Location: Haleakala Summit on Maui, HI
Date: August 14, 2013
Media: Pencil on a white sketch notebook page, reworked in GIMP and color inverted.
Because this event occurred over a short period of time, I was not able to make a detailed sketch of the moon. I’ve added details to one crater that lies near the double star which I’m guessing is Moretus. If anyone knows differently, please make a note of it in the comments.

Thank you.
