Information on Service 'Web interface to FAI 50 cm Meniskus Maksutov telescope archive'

[Use this service from your browser]

Further access options are discussed below

The archive of digitized plates obtained on Wide aperture Maksutov meniscus telescope with main mirror 50 cm at the Fesenkov Astrophysical Institute (FAI), Almaty, Kazakhstan. They represent the results of photometric observations of stars, comets, nebulae etc. for 50 years - from 1950 to 2000. Observations were carried out in the optical range. Telescope specifications: diameter of main mirror D = 500 mm, focal length F = 1200 mm.

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
