The database of Active Galactic Nuclea (AGN) photometrical
observations obtained on defferent telescopes at Fesenkov
Astrophysical Institute, Almaty, Kazakhstan since 2016. Observations
were carried out in the optical range.
Apertif is a phased-array feed system for the Westerbork Synthesis
Radio Telescope (WSRT), providing forty instantaneous beams over 300
MHz of bandwidth. This data release includes the catalogue and image
observed by Apertif covering 26.5 square degree region in the Boötes
constellation at 1.4 GHz. The image is a mosaic of 187 Apertif images
from 8 different survey observations performed between April 2019 and
November 2021. It has an angular resolution of 27×11.5 arcseconds and
a median background noise of 40 μJy/beam. From this mosaic, 8994
sources were extracted and the catalogue is complete down to the 0.3
mJy level. This service queries the mosaic image of the Boötes field.

The Bochum Galactic Disk Survey is a project to monitor the stellar
content of the Galactic disk in a 6 degree wide stripe centered on the
Galactic plane. The data has been recorded from September 2010 to
September 2019 with the RoBoTT Telecsope at the
Universitaetssternwarte Bochum near Cerro Armazones in the Chilean
Atacama desert. It contains measurements of more than 2x10^7 stars.
The second and final data release contains follow-up observations from
January 2017 to September 2019 in Sloan r and i and intermittent
measurements in Johnson UVB, Sloan z and the narrowbands OIII, NB,
Halpha and SII.
The Armagh-Dunsink-Harvard Becker-Schmidt Telescope was deployed at
Boyden Station, Maselspoort South Africa between 1965 and 1970. During
that time, astronomers from Bamberg, Heidelberg, Hamburg and Münster
took astronomical images there, with a focus on old star clusters, the
Magellanic clouds, and the southern milky way. This service provides
scans of the plates obtained.
This archive collects and re-publishes third-party, mostly amateur,
images of the Gaia astrometry satellite to complemement the Ground Based
Optical Tracking (GBOT) effort.
Until Gaia passivation, there is a temporary upload facility
at https://dc.g-vo.org/citigbot/q/upload/form.
This is a deep optical mosaic of the Fornax cluster’s core, covering
1.6 square degrees. The data were acquired with ESO/MPG 2.2m/WFI,
using a transparent filter that nearly equals the no-filter throughput
and thus provides a high signal-to-noise ratio. Based on an
approximate conversion to V-band magnitudes, the unbinned and binned
mosaics (0.24 and 0.71 arcsec/pixel) reach a median depth of 26.6 and
27.8 mag/sq.arcsec, respectively.
