First Published November 10, 1995

Crni Vrh Observatory is operated by a group of dedicated observers. We run a Comet and Asteroid Search Program named PIKA after a Slovene acronym. For that purpose, we designed and built a 0.6-m, f/3.3 Cichocki telescope (named after B. Cichocki). It is custom made, advanced technology, wide-field imaging system, designed for sky survey applications. Since 2004, it operates as a remote robotic telescope. It nightly scans the sky and returns new discoveries of small Solar System bodies, which sometimes threaten our home planet Earth. Recent software upgrade enable us also discovery of distant cosmic explosions such as supernovae, Gamma Ray Bursts and variable stars. See also our 2 minute video presentation and recent updates of the PIKA project.

	Comet C/2025 R3 (PANSTARRS) Unfiltered false color image of comet C/2025 R3 (PANSTARRS), obtained on 2026 Apr. 12 (2h57-3h06 UT) with 60-cm, f/3.3 Deltagraph telescope and CMO. Exposure time was 5 minutes (10x30 seconds). Image scale is 1.46 arc sec/pixel. The comet was only about 15 degrees above the horizon. Copyright © 2026 by H. Mikuz, Crni Vrh Observatory.

Exposure time was 15 minutes (30x30 seconds). Image scale is 1.46 arc sec/pixel. The comet was only 15 degrees above the horizon. Copyright © 2026 by H. Mikuz, Crni Vrh Observatory.

	Comet C/2025 R3 (PANSTARRS) Unfiltered false color image of comet C/2025 R3 (PANSTARRS), obtained on 2026 Apr. 7 (3h00-3h23 UT) with 60-cm, f/3.3 Deltagraph telescope and CMO. Exposure time was 15 minutes (30x30 seconds). Image scale is 1.46 arc sec/pixel. The comet was only 15 degrees above the horizon. The images were taken through the branches of a beech tree, which acted as a Bahtinov mask (see diffraction patterns of bright stars). Copyright © 2026 by H. Mikuz, Crni Vrh Observatory.
