The images were taken with the 6 inch large field refractor Celestron Omni XLT 150 with 750 mm focal length and the large

14 inch Newton telescope with 1400 mm focal length (in memory of the unforgotten telescope builder Werner Reimann).

The Astrolumnia ALccd8L camera is available for taking pictures. Due to its integrated cooling it does not know the disadvantages of the reflex camera. The maximum temperature difference to the outside temperature is up to 45 degrees. This prevents the chip from noise and longer exposure times can be realised. In addition, the star limit size increases at the same time. The chip size is similar to the SLR camera EOS 350d , but the images are available in the full data range of 16 bit. The single exposure times are now up to 2400 seconds.

In recent years, I have been able to use the EOS 350d SLR camera for astrophotography. Thanks to its large CMOS chip , the resolution of 8 million pixels and the built-in Bulb ( long exposure ) function, fantastic shots were already possible. Guiding is done with the ALccd 5 camera. This is placed in the beam path and directs part of the light to the guiding camera, which then tracks a star and sends correction control commands to the mount. This ensures that even after hours of tracking, the sernae remain point-like. After the exposure series, the images are sorted by quality. The best exposures are then added up and finalised with various programmes. In addition, a dark frame is taken after each exposure series. This corresponds to the same exposure time of the last shot. The camera is covered during this process. This is necessary because an uncooled CCD camera produces an amplifier glow at long exposure times. This is then visible on the images. The dark frame is then subtracted from the object images so that the pure image information from the object is available for further processing. The last pictures had exposure times of 10 times 400 sec. or 10 times 600 sec. For some time now I have had a coma corrector at my disposal. This way the image field is completely illuminated up to the corners and the stars remain point-like in the whole field.

NGC 7479 in the constellation Pegasus

The strongly curved spiral arms of this galaxy, about 114 million light years away, resemble a propeller.

resemble a propeller , therefore it got the nickname propeller galaxy.

There are no gravitationally bound galaxies in the vicinity.

It is therefore assumed that the strongly curved arms were formed during an earlier merger with a second galaxy.

Dwarf galaxy Leo1 in the constellation Leo

Leo-I belongs to the local group (companion galaxies of our Milky Way) and is the furthest away from us at about 820,000 light years.

The diameter is about 7000 light years, it was discovered by chance only in 1950.

Leo-I is difficult to photograph because the main star of Leo, Regulus, outshines everything.

Stephan's Quintet in the constellation Pegasus

By mistake, the galaxy NGC 7320 is in the foreground (about 35 million light years away), so that it does not belong to the actual galaxy cluster.

Dwarf Galaxy IC10 in the Constellation Cassiopeia

IC 10 is an irregular dwarf galaxy in the constellation Cassiopeia. It is located in the sky in the middle of the band of the Milky Way. Therefore the view is obscured by numerous foreground stars

of fusion ( tidal tails ).

The pair is about 70 million light years away from us. On this image many background galaxies are still visible

which are about 1 billion light years and more away. Therefore I provide this image as an original.
