GWILYM'S S.T.A.R.S. INTERNSHIP
SUMMER
2000
THIS SITE DISPLAYS SOME OF THE IMAGES COLLECTED
WHILE I WAS ASSISTING
DR. STATLER
WITH EXPERIMENTATION OF THE CAPABILITIES OF A MEADE 10''
SCHMIDT-CASSEGRAIN TELESCOPE. THESE
IMAGES WERE ASSEMBLED FROM A SERIES OF EXPERIMENTAL EXSPOSURES MADE ON
THE MEADE USING A CCD CAMERA.
THE IMAGES HAVE BEEN DARK SUBTRACTED TO REDUCE UNWANTED NOISE AND FLAT
FIELDED TO REMOVE SOME UNWANTED OPTICAL EFFECTS.
NGC 6255(A SPIRAL GALAXY) -Compare
the picture taken on the 10 inch Schmidt-Cassegrain (left) with the
one obtained from the NASA/IPAC EXTRAGALACTIC DATABASE(NED)
433 EROS
- Asteroids are recognizable in telescopic images because they move noticeably
relative to the stars in just a short time. This animation of Eros
was created by combining three pictures of Eros taken consecutively within
a time period of just over an hour.
Eros is an elongated, kidney-bean shaped object . As it rotates,
greater areas are lit by the sun and Eros appears brighter, but sometimes
smaller areas are lit and Eros appears dimmer. The following graphs
indicate the brightness variations of Eros . The first graph
shows the magnitudes of Eros and some field stars in three consecutive
frames taken during the evening. Eros is star #3 The
second graph shows the change in magnitude of the stars relative to their
magnitudes in the first frame. The third graph shows the resulting
lightcurve of Eros. A lightcurve ishows the change in magnitude during
an asteroid"s period of rotation.
