First light for NAOMI

The WHT adaptive-optics system NAOMI was commissioned at the GHRIL
focal station in Sep 2000 by a team from Durham/ATC.
NAOMI/INGRID delivers near-diffraction-limited imaging in J, H and K bands
(FWHM 0.13 arcsec in K), with scale 0.04 arcsec/pixel.  

NAOMI performance figures and further details are given (and a commissioning
image is reproduced) on the ING AO web page:

Information about the detector can be found on the INGRID web page:

Until the commissioning data are fully analysed, we recommend that
the guide star for each target (which can be the target itself) have 
magnitude V < 12.  With further commissioning, e.g. of other readout
modes for the wavefront sensor, it is expected that guide stars up 
to 3 mag fainter will be usable.  Proposals requiring the use of 
fainter guide stars are acceptable, but if allocated time will be
backed up by the time-allocation committee.

Enquiries about performance and other issues can be addressed to 
Chris Benn (crb@ing.iac.es) or Andy Longmore (ajl@roe.ac.uk).  
ING is happy to provide pre-submission technical appraisal of proposals.
