Positions of milky way, planets and zodiacal light bridge at
the astronomical twilight.|
Anyone who's stick it out until the twilight should get ready to expect a delicious titbit: The zodiacal light
shows up over the east horizon and reaches a brightness to cast diffuse but remarkable shadows [look :
here]. The ecliptic light goes from Leo over Cancer up to Gemini, and, at good
conditions, as a light bridge (with counter-glow) over the whole sky !!
And in the ecliptic the planets have their places: Venus -4.2 mag,
Jupiter -2.4 mag and Uranus 5.7 mag.
All of the brightest fixed stars do the honors: Sirius, Procyon, Castor + Pollux,
Aldebaran, Capella, Rigel, Beteigeuze, Regulus, Wega, Deneb.......and on thuesday and friday morning (remember
the early bird....) completed by a crecent moon (with strong ashen light) on this majestic skyview.

Petr Skala - at the 11th. HTT in September 2010 - the maybe first image of
this faint light situation from the lowlands
(alt- though intesive internet recherche - we can't find any
picture of this not taken from beyond a good mountain observation site). Detailed information about this
here [in German]. The picture is 'updated', this means the the actual
planetary positions (middle september 2012, Jupiter, Venus and Uranus) where added.
... And the advanced dawn is also (again) very appealing on the
What an astrononomical romance: |
HTT-early birds (remember....) have the chance to see the crescent moon at
thuesday morning nearby the bright venus and to capture that. A very charming scene, allthough the moon covered
alpha cancri just before and stood nearby allready. And on top the
heliacal rising of Leo, extraordinary impressive on this constellation: Leo literally
seems to escape away from the sun over the horizon.
On next (friday) morning the now very crecent moon showa up beside alpha Leonis - Regulus.
This picture is a composite of a HTT-Photo from Stefan Simon and a graphics from Andreas
Schnabel + Ralf Hofner.
The Venus shows up at -4,2 mag and
18" virtual Ř enlighted by 64%, her
rising each day delay by two minutes: Sep. 13th. - 02:35,
Sep. 16th. - 02:41 CEST.
