New camera with integrated filter wheel carrying standard
photometric BVRI filter set, custom made by Institute of Plasma
Physics in Turnov, provides almost the same field of view and
sensitivity as the old model, but offers much better sampling, which
leads to significantly enhanced resolution of the whole system.
The old camera removed from the telescope (left) is
replaced with the new one (right) with integrated filter
wheel The reflecting telescope was originally designed as Cassegrain
system. The 65 cm primary paraboloidal
mirror with 234 cm focal length is used
with CCD camera in primary focus now.
G2-3200 CCD camera in primary focus of 65 cm telescope Very fast f/3.6 mirror causes quite noticeable coma even very close
to the center of the field of view. This aberration limits both the
resolution and reach, because images of point sources are distorted
and covers many pixels. This is why the G2-3200 camera is used in
connection with Paracorr coma corrector from Tele Vue. Paracorr
eliminates most of the coma aberration and shrinks the image of point
sources so the image become limited more by seeing than by optical
aberrations.
G2-3200 camera fitted with Paracorr PLA-2001 coma
corrector The telescope is used mainly for research of minor bodies in the
Solar system, but also for various research projects performed by
students of the Faculty of Mathematics and Physics of Charles
University in Prague. Example below show observation of Wasp 2
exoplanet transit.
