Utilization of isocon-type television tubes in astrophysical observations
Abstract
Preliminary results are examined of experiments carried out with an isocon-type TV tube sharing a common casing with a single-cascade image converter. The limiting magnitude is found to be appreciably higher than that of the superorthicon LI-217. This, and the high contrast sensitivity and brightness range make the isocon particularly well suited for observation of faint stars and low-contrast objects.
