SOME ASTRONOMICAL IMAGES

Stockholm IR Camera (SIRCA) + NOT Telescope

The Moon - Region around the Archimedes crater

This image is part of an enormous Moon mosaic. The full mosaic uses 4000 images at 500 positions and putting it together without any visible seams was both difficult and took a lot of time (three weeks). See the SIRCA Moon map site.

Mars - Close to 2003 opposition

These infrared images of Mars show both reflected sunlight and heat radiation. The left one is taken in the near-IR and Mars looks a lot like the eye would see it, with the south pole clearly visible as well as continents.

The thermal (heat) image to the right is taken in the so-called M band and clearly shows cold and warm regions on Mars. The south pole is clearly cold and even with a phase of 93.5% it is possible to see the whole planet due to heat radiation from the dark side (i.e. to the right). Especially interesting on the dark side is the 'heat band' at Mars equator.

The Sun in H alpha

This is what the Sun looks like in a Hydrogen alpha filter (656nm). Such a filter makes it possible to see granules and prominences in addition the usual Sun spots.

To make the image, 9 short exposures (surface details) and 9 long exposures (prominences) were developed, scanned and added together.

EXPERIMENTAL PHOTOGRAPHY

Canon Powershot G3 (15 second exposure at f / 8)

Some trick photography?

Not really, just a long exposure and switching seats every 5 seconds.

But that could be quite tricky too... :-)

Street lights - Moving camera

In this way one can easily see that the street lights run on Alternating Current (probably 50 Hz). This is the reason for the dotted curves since the flux output varies.

This effect can also be seen with large snowflakes close to street lights.

Boiling water - Extremely short exposure

Taking a photo of boiling water with an extremely short exposure time 'freezes' the water :-)

Southern Milky way - Multiple exposures

Stacking eight 15 second exposures of the southern Milky way from one of the darkest and best astronomy sites in the world, VLT/Paranal/Chile in the Atacama desert gives a picture like this one.

Ahu Tahai - Easter Island

I placed my digital camera on a tripod and used a flashlight to lit up the statue (called Ahu Tahai). Easter Island (especially away from the roads) is a very dark place, so I "painted" the statue with light, sweeping it with a flashlight during each 15 second exposure. I took four 15 s exposures straight after each other, and added them to make the statue part. The clouds & sky are from one of the exposures (the last one) to avoid star/planet trails. Since the clouds moved pretty fast, they make a nice "spooky" effect because of the 15 s exposure time. Taking the night photo was a tricky thing, one have to look out for the wild dogs and horses (and it's completely dark!) This image became Astronomy picture of the day May 24, 2004
