Mars Opposition 2007 21.12.2007 / 20:16-20:21 UT

Mars at Opposition 2007

The picture reveals some fine detail, although the diameter of the planets disc was only 15.9".

Celestron 8 at f/30 (3x TeleVue Barlow lens) and DMK21AF04.AS. Four different sequences for IR, R, G and B were acquired and averaged to this final image, image resized to 80%.

3030 Vehrenberg 05.12.2007 / 10:08 UT / 10:30 UT / 11:16 UT

Asteroid 3030 Vehrenberg

I have created a little GIF-animation, showing the path of asteroid 3030 Vehrenberg in a time period of a little more than one hour. The asteroids brightness was about 18.1 mag. Three images (each 240s integration time) were remotely taken using GRAS-005 of Global Rent a Scope (Takahashi Epsilon 250, SBIG ST-10XME). Only dark subtraction was applied.

Warning: Image size is 1.723KB and 1024x768 pixels.

Messier 81 L-RGB 03.12.2007 + 16.12.2007

Galaxy M81 in Ursa Major

This is my first LRGB image of M81. The image was remotely acquired over the internet, using a Takahashi TOA 150 and an SBIG STL-11000. For more details, please click on the thumbnail-image.

International Space Station (ISS)

After two unsuccessful attempts of imaging the new ISS, finally I've got one new shot - yippee!

Three frames were combined - to see the individuals, please click on the thumbnail.

Jupiter and Europa Shortly After Opposition

For northern latitudes Jupiter still is a difficult object to observe because it is very low above the horizon. I decided to use the TAK FS 102 for this image because it is less sensitive on seeing effects. Compared to earlier images the face of Jupiter has changed dramatically. The SEB and the GRS are very faint. The bluish dot in the upper right corner of the image is identified as Jupiter's icy moon Europa.

557/2400 frames were selected and stacked in Registax, final processing with IRIS and Photoshop.

First Light

The picture on the left is a preliminary result of a test run of my new DMK 21AF04.AS camera which shows Saturn with IR/UV cut filter. I am planning to use this camera together with a filter wheel (Atik) and Astronomik LRGB filter set or with the ToUCam for RGB (in this configuration the DMK will produce the luminance layer). The DMK is connected to the Laptop via FireWire (IEEE 1394) which allows a max. of 60 fps. of uncompressed data (depending on the integration time). The video stream for this image was 8 fps.

Please click here to see the first L-RGB result with Astronomik filter set.

International Space Station (ISS) after Service Mission STS-116

The sequence on the left clearly shows the newly installed P3/P4 truss and solar arrays. I think the view is from below the station this is why the older P6 solar array is barely visible. Click on the thumbnail for further info.

Partial Lunar Eclipse

The image shows the Moon just 4 minutes after the maximum of the eclipse. The Earth's shadow is covering about 1/5 of the moon. The detail to the lower right is an airplane crossing the view. Zeiss Diascope 85 T* FL and Sony digital camera.

Red Spot Junior

For northern latitudes, Jupiter is difficult to observe currently. The planet was only 18° above the horizon. To the lower left of the Great Red Spot one can see another detail which is called Red Spot Junior. This spot is known for years as Oval BA and recently changed color from white to orange like the GRS. Ganymede can also be seen to the lower left of the image.

Saturn Jan 28, 2006 Takahashi FS102N 28.01.2006 / 23:47 UT

Saturn at Opposition

The planet is now visible the whole night and the apparent diameter is max. This night was very cold (-10°C) with poor seeing conditions, but better resolution than my previous image. Note the crepe ring (faint most inner ring), Cassini Division very sharp and prominent.

Takahashi FS-102N plus TeleVue 5x Powermate; Baader IR/UV cut filter, ToUCam pro web cam. 200/1800 images selected and stacked with Registax. Final processing with Photoshop.

14.01.2006 / 21:31 UT


North Pole appears slightly bluish, Cassini division clearly resolved, central cloud belt prominent, nice shadow on the ring near the south pole. Full Moon was very close, -5°C outside temperature.

Saturn and it's moons Dione, Rhea and Titan

It's difficult to catch Saturn's moons with an unmodified web cam. Saturn is over-exposed to detect the faint moons. Click on the image for more detail.

21.11.2005 / 19:20 UT (RGB) / 19:32 UT (IR)


My first shot of Syrtis Major. Also most prominent is Arabia Terra and the giant Hellas impact crater. Very faint southern polar hood, north pole haze.

New Image technique: RGB with Baader IR/UV cut 300 out of 2000 frames stacked. Luminance is 300 out of 2000 frames with Baader IR pass filter. Celestron 8, eyepiece projection 20 mm TeleVue Plössl, ToUCam Pro web cam. Excellent seeing, -2.3°C outside temperature...

06.11.2005 / 20:50 UT


This image shows the famous Eye of Mars and the Tharsis region. The bright spot on the upper left is identified as Olympus Mons volcano. The volcano seems to be covered by orographic clouds, because it is so prominent. Faint southern polar hood is detected, northern polar haze. 160/1000 images stacked with Registax. C8 in eyepiece projection (20mm TV Plössl), Baader IR/UV cut and ToUCam Pro web cam. Resized to 80%. Strong wind this evening.

28.10.2005 / 23:13 UT


The image on the left shows Mare Sirenum, Hespetia Planum and the Elysium Planitia (brighter spot to the north), the north pole is covered with ice clouds (bluish color). South polar hood seems to be completely melted.

400 out of 2000 images stacked with Registax. C8 in eyepiece projection (20mm TV Plössl), Baader IR/UV cut, ToUCam Pro web cam. Resized to 80%.

31.03.2003 / 19:07-19:13 UT

International Space Station ISS

Tracking the ISS via finder scope is a big challenge! Many interesting details visible: Main solar panel, central modules, Progress docked, S1 radiator (left), installed in October '02 and P1 radiator (right) of central modules installed in November '02. Click on the image for more info.

The black dot in Jupiter's atmosphere is the shadow of Europa. I have never seen such an event before! Seeing was excellent, many details are visible. 272 frames stacked with Registax, resized to 50%.

09.03.2003 / 19:01 UT

Jupiter with GRS

The sky just cleared for a few minutes. Note the big white clouds in the SEB, many interesting details visible due to good seeing that evening.

Outside temp. was +7°C.

22.02.2003 / 20:25-20:52 UT

Jupiter: GRS transit captured
