Distant galaxy MS 1512-cB58
The image reveals the gravitationally amplified, elongated image of the very distant, 20.6-mag galaxy MS 1512-cB58 (indicated with an arrow). The photo is is a reproduction of a composite image of the field around the distant cluster of galaxies MS 1512+36 (redshift 0.37), obtained with the WFPC2 camera on the NASA/ESA Hubble Space Telescope.
It is based on exposures in two filters (F555 + F675). The observations are described in a research paper by Seitz et al. (Monthly Notices of the RAS, August 1998, Vol. 298, p. 945 ff). The lensed image of the galaxy MS 1512-cB58 is seen at an angular distance of about 5 arcsec from the centre of the cluster. The north direction is at about 1 o'clock and east is at 10 o'clock. The field measures approx. 45 x 60 arcsec2.
