The Wide Field Camera (WFC) is an optical mosaic camera for use at the prime focus of the
2.5m
Isaac Newton Telescope (INT).
The WFC consists of 4 thinned EEV 2kx4k CCDs. The CCDs have a pixel
size of 13.5 microns corresponding to 0.33 arcsec/pixel. The edge to edge limit
of the mosaic, neglecting the ~1 arcmin inter-chip spacing, is 34.2 arcmins.
The cycle time for the whole mosaic is around 42 seconds. A maximum of 6 filters
could be installed in the wheel. Both broadband and Stromgren filter sets are
available, as well as a range of narrowband filters.
IMPORTANT: in case a long run is going to be covered by several observers, please let us know well in
advance so that student support can be scheduled each time a new team goes up.
News:
September 2012: Two new narrow band filters arrived
(NOVA782HA and
NOVA804HA),
being offered by the Netherland Reasearch School for Astronomy (NOVA) which provided the funding
(PI: David Sobral).
August 2010: On a shared-risk basis, binning is supported for all chips and windowing and/or binning are supported for chip 4 only
