2005
- Newly designed imaging backend for RCOS20 - showing RCOS
Flat Field Corrector in custom machined adapter installed in a new precision
instrument rotator, modular remote scanning dual port remote DC servomotor
focusable OAG head, and prism pick
off tubes (
which will be mounted in OAG head)
2005

guideport design with remote individual autoguider focus
control. The OAG also incorporates 25 mm of remote controlled radial scanning
across the focal plane. The OAG is mounted on a new high load high resolution
Instrument rotator using a modified Klinger RT200 stage and made compatible
with the RCOS Telescope Control System and software.
