This is probably my last Rho Ophiuchi region for this year.
It has been captured yesterday, 100km outside Belo Horizonte in the Serra do Cipó area. It is a composition of 20 frames of 300s each with a 200mm F2.8 lens.

Regards,
Roberto

: Aurora over Otertind

The best time for Aurora Borealis is in autumn and spring when the earth axis is more directional toward the solar wind. So there was I higher chance for northern lights on my trip through the Signaldalen Valley in Norway in autumn 2010. We almost experienced aurora every second night, but in this case it was more beautiful than usual as a very colorful display with beamers appears in front of the impressive mountain peak of Otertind.

: Illuminated Twilight Shelf Cloud

A shelf cloud is a laminar gust front of a thunderstorm. The gust front occurs when downward winds hit the ground and cold pool is sidelining into the moist, still warmer air mass in front of the storm pushing a new updraft. Horizontal flow pattern and drier air in higher levels (elevated mixed layer) in the storm environment create this typical layered look. The storm produced plastic, illuminating lightning that makes structures even more visible at late night hours while early dawn adds little more color to the whole photogenic atmosphere.

: Winter Dawn

When shadow of Earth flee on the opposite side of sunrise, the Belt of Venus sometime creates a dramatic color gradient and light over the landscape, especially in clean air masses. I almost waited for the day's first light rays but this moment short before still impressed me more than the sunrise itself as it is rarely so intensive. So sometimes you should change the view at dusk and dawn time ;-)

Perseids, Milky way and Gegenschein
Copyright: Petr Horálek (Úpice observatory)

A mosaic of maximum of Perseid meteor shower from Ivan Dolac (Hvar island, Croatia) above peaks Začerbina and Gvozd. The image shows 79 meteors of Perseid meteor shower cought from 7th to 14th August 2013. The brightest meteor was about -8 magnitude. I used stronger saturation in brown-red color to highlight the interstellar matter of Milky way and also stronger gamma for zodiacal bridge and Gegenschein, which is up-right on the image.

They reached from horizon to horizon.

Location: "Observatorio del Roque de Los Muchachos" (La Palma, Canary Islands. Spain)
Equipment: Canon EOS 5D Mark II + Samyang 14mm 2.8 + tripod + intervalometer.
EXIF: 14mm - ISO 6400 - F/2.8 - 35 segundos.

This photograph shows the 10.4-meter Gran Telescopio CANARIAS (GTC - http://www.gtc.iac.es/GTChome.php), located at the Observatorio del Roque de Los Muchachos (http://www.iac.es/eno.php?op1=2&lang=en) in the island of La Palma (Canary Islands, Spain), next to the heart of our own galaxy, the Milky Way. The silhouette of a person to the right of the telescope is dwarfed by the splendour of La Palma starry night and the GTC. The picture dramatically shows the evolution of thousands of years of human exploration of the skies. The GTC, with a light collecting area over two million times larger than the human eye, is one of the most advanced machines designed to explore the Universe.

Autumn auroras with twilight

© Thomas Kast, All Rights Reserved
http://www.facebook.com/salamapaja

On August 27, 2013, the Earths interplanetary magnetic field (IMF) tilted and solar wind was able to flow into our atmosphere creating wonderful Northern lights. This photo is taken at a lake shore near Oulunsalo, Finland. You can see the reflection of the twilight at the bottom of the photo. The best part of this 'twirl' lasted about 5 minutes before it got weaker. What you see is a 114 degrees view. For any more information, don't hesitate to contact me.

Above the Glacier
Author: Lorenzo Comolli ( http://www.astrosurf.com/comolli/index2.htm )
Description: late summer is the best season to look at the glaciers without a snow coverage. This image seems to be in daylight but was gathered in moonlight, on the night of Full Moon, this month. The Pers and Morteratsch Glaciers are visible below from the viewpoint of Diavolezza, 3000 m, Switzerland. The mountains are Piz Palù (3901 m) and Piz Bernina (4049 m), on the Swiss-Italian border. Only a little bit of Milky Way is visible due to moonlight "pollution". Canon 5D + Samyang 14mm at f/4, 30 s exp.
