Mars

These photos were obtained using the LRGB technique, which involves composition of a special black&white image with an image carrying information about the color. Surface of Mars shows in good detail contrast in near infrared segment of light spectrum, therefore the black&white image has been made using an IR-Pass filter. Atmospheric instability also has lesser impact at this part of spectrum comparing to the visible spectrum, an extra reason for this shot to contain more finer surface details. The image carrying information about color has been made using filter which pass through visible part of spectrum and cuts of infrared and ultraviolet areas (UV/IR Cut filter). This cutoff produces an image with a more correct white balance and saturation, which is composed with the black&white image in a special way.

Mars rotation images were obtained using the classic webcam method. A russian reflector TAL 200K with a barlow lens was used. Images has been preliminary proccessed and composed.

Mars rotation during the one night. White dots serves as a time tracking point for a surface detail.

Saturn

Saturn composite images were obtained with the webcam method. Philips ToUCam Pro PCVC740K was used, attached to the reflector TAL 200K, along with the 3x Barlow lens. Computer processing was used later to make one final composite out of tens of single frames.

This is the green channel of previous image, which reveals the lined structure of Saturn's belts and root of the ring's shadow.

Jupiter

Jupiter composite images were obtained with the webcam method. Philips ToUCam Pro PCVC740K was used, attached to the reflector TAL 200K, with and without the 3x Barlow lens. Computer processing was used later to make one final composite out of tens of single frames.

On this image, obtained without the Barlow lens, along with the two of Jupiter's satellites, is clearly visible complexity of belts and distinctive Red Spot.

Transit of the Jupiter's satellite Io across the disc of giant planet was in progress at the moment of shooting. Black spot represents the shadow which the satellite casts on Jupiter's disc.

The Io's shadow is clearer and Red Spot's structure is also visible (dark vortex inside of the Spot). Also Jupiter's rotation can be noted against the previous image.

Venus transit 2004-06-08

Venus transit across the Sun's disc on 8th of June 2004, first in 122 years, was the main occupation of Public Observatory's observing team. Carefully prepared associates and employees, split in several groups, approached the realisation of different observing projects.

At the first picture you can see the Sun's disk in the moment of transit, just before the III contact at 13:03:50 CEST. Second image was formed out of 17 different shots, obtained in the interval of 20 minutes, between 07:39 and 13:04 CEST. For the appearance of Sun's disk and spots only one, the best image was used, to eliminate their smearing. Both images were made with camera Minolta 5Xi and Kodak Professional Technical Pan 2415 black and white film, attached to the Russian reflector TAL 200K (f/20) with Sun filter (density 3.8). Filming was carried out from Lipovica forest near Barajevo, Belgrade.

Mercury transit 2003-05-07

Final appearance of the composite was formed out of 17 different shots, obtained in the interval of 20 minutes, between 07:17 and 12:17 CEST, from Lipovica forest near Barajevo, Belgrade. For the appearance of Sun's disk and spots only one, the best image was used, to eliminate their smearing. A Russian refracting telescope 80/800 mm was used, along with the 2.5x Barlow lens, with the effective focal length of 2000 mm. For filming, camera ASAHI/Pentax SP1000 with ISO/21° color film was used.

The function of distance of Mercury's disc from the Sun's edge is presented on the graphic. Contact times were obtained by processing the observing data.
