The new Kron photometer is a traditional-style
aperture photometer using a photon-counting
photomultiplier tube (PMT) system. However, unlike previous
Lowell photometers, the Kron photometer was designed to be
run from the control room and so has an acquisition
CCD camera and motorized wheels for remote operations.
As such, it can be used in conjunction with the autoguiders
at the 72-inch and 42-inch telescopes; it can also operate
at the 31-inch telescope. A scripting
language permits the automation of observing sequences,
while communication with the telescope MOVE computer allows
the photometer to direct the telescope to new locations. Designed and constructed in-house at Lowell
Observatory during 1998, primary funding for the new photometer
was generously provided by Gerald and Katherine Kron, longtime
supporters of Lowell Observatory.
