If your camera has interchangeable focusing screens, use
a fine-ground glass screen. It will be much brighter and will
make focusing easier.
Vibration During Exposure
It is very important to minimize vibration during an exposure. If
your camera is equipped with a “mirror lock-up,” use it before
you start the photo. Use a cable release to trip the self-timer
on the camera. To further reduce vibration, the best solution is
the “hat trick.” Set your camera’s exposer time (shutter speed)
to the “B” (bulb) setting, which will hold the shutter open indefi-
nitely when triggered. Hold a black piece of cardboard or a “hat”
in front of the telescope (but not touching it) while you open
the shutter. Wait approximately 8 seconds and then remove the
“hat.” It is important that nothing touch the telescope or camera
during the exposure. When you're finished exposing, place the
“hat” in front of the telescope again and trip the cable-release
to close the shutter.
Precautions
Be very careful not to release the set screw holding the eye-
piece before removing your camera and tele-extender. If the
screw is released and the eyepiece falls through the extender
tube, it can damage your camera.
