A. Stars.

I. Capella.

On 20 June 2000 I was able to record this picture of Capella, a red star, which stands rather low above the horizon (RA 5h.17', DEC 46. 00'). Because of air pollution and turbulance this took quite an effort of some 150 pictures.

The instrumented telescope consisted of a 4" refractor equipped to F/39.2, a flip-mirror finder with an illuminated cross wire in the eye-piece and the MX5-C CCD-camera. The exposure was 3 secs.

 

II. Lyn 19A.

Another example of a (double) star, but now higher on the sky.

 

III. Umicron.

 A star in Ursa Major.

 

IV. Upsilon.

A star in Ursa Major.

 

V. Xiaur.

VI. Dubhe.

!Splitting 0.5":at the optical limits of the system!

A light-yellow double star in Ursa Major. There was a major difficulty in splitting Dubhe as it is also a variable star. Although the magnitude is high (Magn.1.81), the variations in intensity caused it to take some 230 exposures, spread over different nights at good-seeing and hardly any turbulence, before this image came out. It is at the rim of optical resolution for my system as its max. resolution is 0.6".The position of Dubhe at 123.6 LY is 11h03m42s for RA and 6145'07" for DEC. The angle between both components is 221 and the distance in between is 0.5". The exposure time was 10 seconds. 

VII. Eltanin.

One of my first images with the 150mm Chromacorr O1 installed in the C102-HD at F/39.2 is the light-orange 2.24 Magn. star Eltanin in Draco.

B. Planets.

 I. Jupiter.

Taken on 23 December 2000 around 02.00 h this picture was composed out of 140 exposures at 0.13 s and F/39.2. Image processing was performed with ASTROART 2.0. The red moon is Io. One can say that the resolution is excellent. Not only the great red spot can be observed but the convection patterns can be discerned, too. Some 11 to 12 lines can be seen here!

Another beautiful picture of Jupiter taken on------------------------------------------ This is a composition of 86 images taken at -0.26 secs. each on 7 April 2002 with

22 December 2000 around midnight!------------------------------------------------- - the Chromacorr installed in the refractor.
II. Saturnus.

A composition of 55 exposures, processed with ASTROART 2.0 under the same circumstances as mentioned under I.

 

III. Venus.

This is how mysterious Venus appeared on that night of excellent seeing. A composition of 46 images.

IV. The Tycho-area of the moon of planet Earth.

A composition of 48 images exposed at 0.3 seconds each and taken with the C102-APO at F/39.2. The resolution is about 500 meters.
