Crni Vrh Observatory

MPC observatory code 106
Longitude: 14^o 04' 16" East; Latitude: 45^o 56' 45" North; Altitude: 726 m
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.

Image is a combination of 49 guided 30-second exposures at ISO 1600. Copyright © 2024 by J. Vales, Crni Vrh Observatory.

	Comet C/2023 A3 (Tsuchinshan-ATLAS) Image of comet C/2023 A3 (Tsuchinshan-ATLAS), obtained from Crni Vrh Observatory on 2024 Oct. 20 (17h38-18h00UT) with 15-cm, f/3.5 Quattro-150P telescope and Canon 6D camera. Exposure time was 20 minutes (40x30 seconds) at ISO 1600. Image scale is 5.1 arc sec/pixel. Field size 3.56 x 2.37 deg. Median combined to enhance the comet detail and reduce the star trails in background. Copyright © 2024 by H. Mikuz, Crni Vrh Observatory.

Image is stack of 12 guided 1-minute exposures at ISO 1600. Some cirrus clouds interfered observation. Copyright © 2024 by J. Vales, Crni Vrh Observatory.

	Comet C/2023 A3 (Tsuchinshan-ATLAS) Image of comet C/2023 A3 (Tsuchinshan-ATLAS), obtained from La Palma on 2024 Oct. 14 (19h26UT) with Canon R6 and 100-400 mm telephoto lens. Copyright © 2024 by J. Skvarc, La Palma, Canary Island.

	Comet C/2023 A3 (Tsuchinshan-ATLAS) Image of comet C/2023 A3 (Tsuchinshan-ATLAS), obtained on 2024 Oct. 14 (17h25UT) at University of Ljubljana Astronomical Observatory with 200 mm, f/3.2 lens and Canon 6D. Image is stack of 30 1-second exposures taken from fixed tripod at ISO 1600. Faint comet-like object near the head of A3 is actually periodic comet 13P/Olbers. Copyright © 2024 by H. Mikuz.
