On Aug 13, 2015 a thunderstorm hit almost entire Belgium with heavy rain, wind and lighting flashes all around.
I was able to make some pictures trying out different settings. This time is used a very small aperture of f/20 and increased time up to 30s.
Both pictures are edited using photshop CS4.

String Theory Universe
After a stressfull day it's always important to relax. Why not attending a public lecture on the tring theory universe at the university of Leuven. The lecture on tuesday gave a short overview on the string theory and the beginning of the universe. But most relevant discussion was about spacetime and how string theory describes gravity. This was done by holographic principle based on the fact that information not can be lost - even in black holes.

Phantastic Optical phenomena by the sun
Fast changing weather conditions also trigger optical phenomena as the sun interacts with ice chrystals in the atmosphere (high clouds).
In this section I show my most recent picures from most common halo's, sundogs and rainbow.
On august 3, 2015 I could make the the picture below. After modification using CS4 the picture shows different phenomena. From top to bottom :
Circumzenital Arc
"attached" Supralateral Arc
Pary Arc and Tangent Arc
22° Halo Arc
On the right/low end a sundog
Modiefied Using CS4 B/W What do you see ... in theory |
The above is not my picture but it shows what is seen!
The picture below shows on top a part of 22° Halo taken on August 2, 2015
Above the bright rainbow it's hard to see but there is a faint second rainbow, July 27, 2015
Beautiful sunset with left and right hand sundogs. On the right most probably a piece of the parhelic circle. Picture taken August 2, 2015

The sun today
Hot weather today and open sky with high clouds. But still able to observe the sun. I made a compilation of the sun using Orion XT12 with Baader film and 24mm Ocular. Two small sunspots are seen on this picture. The other picture is black/white picture from PST 40mm with 24mm Ocular. On the right / low corner you can observe a "small" prominence.
