Saturn at -6.2°C temperature!

I did some tests, but could not improve quality significantly.

08.12.2002 / 20:29 UT


These four images are illustrating the RGB-technique. The IRIS program is separating a sequence into red, green and blue frames. Later they are combined into one color image.

Open Cluster NGC 869 and 884 in the constellation Perseus

With a magnitude of 5.30 these clusters are visible to the naked eye. C8 at f/5.9, Canon T70 SLR; 36min. exposure on Kodak Farbwelt 400 ISO. (Be aware: 200 KB!).

Andromeda Galaxy M31; Elliptical Galaxy M32 (upper left area) and M110 (lower left area)

These galaxies belong to the so called local group, a cluster of galaxies which our Milky way is also part of. Distance to earth is ~2,2 million light years (our cosmic neighbor..).

C8 at f/5.9, Canon T70 SLR, Kodak Farbwelt 400, exposure: 40 minutes.

Planetary Nebula M57 (Constellation Lyra)

In a Nova-Eruption, the central star blasted his outer parts into space. The gas is still expanding at about 19 km/s. Click here to learn more about M57.

Near Earth Object 2002NY40 passing the Constellation Sagitta

This asteroid is 0.5 - 0.8 km in diameter and passed Earth at a distance of 520,000 km (behind the orbit of the Moon). The left image is the original, the image on the right is a calculation from the Cartes du Ciel software. C8 at f/5.9 (Alan Gee Telecompressor), SLR camera on Kodak Farbwelt 800 ISO.

Global Cluster M13

This star-cluster is 22,500 light years away. Its diameter is 100 light years. C8 at f/10, duration approx. 12 min. with SLR camera on Kodak Farbwelt 800 ISO.

The Barringer Crater in Arizona

The best preserved meteorite impact crater on Earth. The crater is 50,000 years old and 1,265 m in diameter! The impact force was equal to 20 million tons of TNT. The first image is a panoramic view of the crater (a special software was used to create this panoramic view). The second image shows the crater rim from the distance.

The Moon

Crater Deslandres, in the eastern area Walter, south Lexell.

20.04.2002 / 22:04 UT

The Moon

Crater Alphonsus, Arzachel, Thebit (from top). In the left area is the Straight Wall and westwards the crater Birth with the Birth Rille. Mosaic from 4 images.

The Moon

Mountain chain of Montes Apenninus. On the top is Mt. Hadley. This was the landing site of Apollo 15 in 1971. 10/50 images stacked. Click here for a detailed image from NASA.

20.04.2002 / 22:00 UT

The Moon

This is a high resolution zoom of the landing Area. Mt. Hadley can be seen in the lower mid. section. The landing area was east of the Hadley-Rille. The two craters in North-West are approx. 1.5 km in diameter. Click here for a very interesting panorama-image of this area taken by Apollo 15 crew member Jim Irwin.

Edit: Recently, the Kaguya-Selene spacecraft has imaged this area.

The Moon

Alpine Valley. South of the valley is the little crater Trouvelot. Diameter of Trouvelot: 9 km.

Click on the left image for an animated GIF (Black/White) showing the rotation of Jupiter! ToUCam Pro in 320x240 mode.

C8 eyepiece projection 25 mm. Excellent seeing that evening.

The famous White Oval

It can be seen south of the Great Red Spot. A few weeks ago GRS and WHO had a close encounter and it wasn't for sure if the white oval would survive...

TouCam Pro in 640x480 mode, 200 frames stacked. Excellent seeing.

16.03.2002 / 19:39 UT

16.03.2002 / 19:37 UT

Jupiter and it's moon Io

A few minutes later Io was no longer visible, because it moved behind the planet. The Great Red Spot is also visible in the left area of the SEB. With the three images made on the 16th, the rotation of the planet is also visible.

TouCam Pro (640x480) - 150 frames stacked. Excellent seeing.

GRS is near the central meridian. C8 at f/10, 150 frames stacked. Poor seeing.

Saturn with analog SLR camera Feb. 2002

My very first attempt of imaging Saturn

From this image I learned that I have to switch to the digital technique to achieve high resolution.
