OBSERVING OPPORTUNITY WITH THE WHT – PRIME FOCUS IMAGING
During the integration of WEAVE at the WHT, an opportunity has arisen
to offer service-mode imaging with a camera (the QHY) mounted behind
the new WEAVE prime-focus corrector, during April and May 2021.
The QHY camera (model QHY6000L) is based on a back-illuminated
scientific CMOS detector, with 9576 × 6388 3.8-μm pixels, giving a
field of view of 10.7′ × 7.1′, at a scale of 0.067 “/pixel, which will
be binned 2×2 or 4×4.
The camera is equipped with a 5-position filter wheel, offering the
following filters: Sloan u and i, Astronomik B (which might soon be
replaced by Sloan g, with similar bandpass), Astronomik R (might
soon be replaced by Sloan r) and a broad-band (‘clear’) luminance
Further details about the instrument can be found on the instrument
The service application form can be found on:
The form can be used to submit proposals,
at any time until 11 April 2021 (24:00 GMT).
The proposals will be graded by the three national TACs and
the highest-ranking proposals will be queued for service-mode observing.
