Table information for 'upjs_img.main'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

The images in this collection were acquired to monitor selected sky fields around eclipsing binary stars at the Kolonica Observatory, Slovakia.

The Kolonica Observatory is located on the Kolonica Saddle and is operated by the Vihorlat Observatory in Humenné. It lies in the northeastern part of Slovakia, within the Poloniny Dark-Sky Park, a location with the darkest night skies in Slovakia and among the darkest in Europe.

Two small telescopes were used to obtain the images in this collection. The first telescope, named ZIGA (PlaneWave CDK20 — Corrected Dall–Kirkham), has a 508 mm aperture and is equipped with a Moravian Instruments G4-16000 CCD camera and UBVRI Bessell photometric filters. The second telescope, named Alica (Explore Scientific MN-152 — Maksutov–Newton), has a 152 mm aperture and is equipped with a Moravian Instruments G2-8300 CCD camera and g′ r′ i′ Sloan photometric filters. Both telescopes are currently in operation, and the archive is expected to be updated with new data.

We publish the photometric time series derived from these images in the upjs_ts collection.
