Solar Filter (#94138) - Celestron Solar Screen solar filters permit direct
Observation of the Sun with complete safety. These filters, which transmit
001% of visible light, allow you to see sunspots as they move with the Sun's
rotation across the solar disk. In addition to reducing the intensity of the
Sun’s visible light, they also block 99.999% of invisible infrared light. The
Celestron Solar Screen? solar filters are made of precision engineered
aluminized Mylar? polyester film. A layer of aluminum is vacuum-depos-
ited on one surface of the dual sheets of Mylar? used to make each filter.
The aluminum coating produces a cool, comfortable pale blue image of the
Sun. (A 3121 orange eyepiece filter works well in conjunction with this filter
to produce a more natural colored Sun with greater contrast.) This filter can
be used for visual observation and photography.
T-Adap ter (#93634-A) - A T-Adapter (with T-Ring) allows you to attach your
camera to your C4.5 Newtonian for prime focus photography and is used for
short exposure astrophotography. It can be used for long exposure work if
you are using a separate guidescope.
T-C Adapter (#93636) - This adapter allows you to couple a video or movie
camera to a telescope. The video camera must have a removable lens with a
standard "C" thread. The T-C Adapter threads into the camera and then
onto the T-Adapter.
T-Ring - The T-Ring couples your camera body to the T-Adapter, radial
guider, and tele-extender. This accessory is mandatory if you want to do
astrophotography through the telescope. Each camera make (i.e., Minolta,
Nikon, etc.) has its own unique mount and therefore its own T-Ring.
Tele-Extender (#93647) - The tele-extender is a hollow tube that allows you
to attach an eyepiece and a camera to the telescope. This accessory is used
for eyepiece projection photography. The tele-extender threads into the
focus tube and allows you to insert an eyepiece as well. When the eyepiece
is not inserted, the tele-extender can be used as a T-Adapter.
Vibration Suppression Pads (#93503) - These pads rest between the ground
and tripod feet of your telescope. They reduce the amplitude and vibration
time of your telescope when shaken by the wind or bumped accidentally.
