Photographs of astronomical objects outside of the Solar System. Comments and technical data can be found next to each image.
Images have been divided into chronological sections, and most of these correspond to a particular development phase of the imaging system.


Vidojevica Mountain, July 2016.

A few months ago a shiny new ASA AZ1400 telescope was installed here - a fork mounted 1.4m Ritchey-Chretien with two camera ports. The observatory now has two stationary instruments and becomes a much more serious research facility. And wild strawberries can still be found in the forest even in late summer, not to mention blackberries and the rest of the nature treats...

Vidojevica Mountain, July 2015.

Chance had it that a friend of mine unexpectedly borrowed me a brand new Sbig STT-8300 camera with a generous set of seven Baader filters (R, G, B, L, H-α, O-III and S-II). In just two days I managed to make the required adapters to mount it on my instrument and set the balance properly, so the camera got its first light under the dark skies at the Vidojevica mountain summit.

Vidojevica Mountain, April 2012.

The summit of Vidojevica mountain in southern Serbia has been chosen as the site where the Astronomical Observatory of Belgrade is going to build its remote observing site. At the time of this writing a dome harbouring a 60cm Cassegrain telescope exists here, together with a separate building where the living quarters are. In the future another larger telescope is planned, which should occupy the flat plateau at the summit. The nearest access road is from Prokuplje town, and this location is often visited by both professional and amateur astronomers.

Divčibare, March 2012.

These are the first deep sky test images obtained with the RC 250 telescope and ASA DDM60 Pro mount. Direct drive mounts are not happy when placed on soft ground, so next time I'll need to find a harder surface for better tracking precision. All of the images were obtained with pointing models only, no autoguiding. This imaging session provided valuable experience which I will use to further enhance the system.

Old images from New Belgrade

These are among the first images that I took through a telescope. The building that I lived in was located in the densely populated area of New Belgrade, with gross light pollution and unstable air. Fortunately, that building was one of the tallest in the area, and the roof perimeter had a rather high rim that acted as a shade, so it was possible to catch some starlight from there. All components of the imaging system were still in their juvenile phase, rodeo ride would be a mild comparison to the manual guiding of the TAL 200K's GM3-RA mount through a clumsy 50mm f/14 refractor. But in the end, robust Russian design proved that there was ample space for improvement, and the astrophotography adventures begun.
