ADAPTER, RASA 8 #93405
CANON MIRRORLESS CAMERA
ADAPTER, RASA 8 #93406
INSTRUCTION MANUAL
The camera adapter connects your mirrorless
camera to the RASA 8. It requires the retaining ring,
which comes with the astrograph.
TO ATTACH YOUR CAMERA
1. Place the retaining ring over the camera adapter.
2. Thread the retaining ring clockwise onto the lens
group cell at the front of the RASA 8. Tighten the
retaining ring until the camera adapter is snug
against the cell, but do not overtighten the ring.
3. To connect the camera body to the camera
adapter, fi rst line up the dot on the camera’s
bayonet mount with the white dot on the adapter.
Push the camera onto the adapter and rotate the
camera clockwise. When connected, the camera
will click into place.
Once the camera is installed, you can adjust its
orientation by slightly loosening the retaining ring.
Loosen the ring no more than 1/8th turn, rotate the
camera as desired, and retighten the ring.
CAUTION: Overtightening the retaining ring can cause the
lens group cell to rotate relative to the Schmidt corrector,
which may affect optical alignment. Keep the camera
adapter snug against the lens cell, but do not overtighten
the ring.
TO REMOVE YOUR CAMERA
1. Hold the camera and completely unthread the
retaining ring from the RASA 8 lens group cell.
2. Press and hold the camera’s lens release button.
3. Rotate the camera adapter counter-clockwise.
Since there is not much room between the camera
adapter and the camera body, you may not be able
to press the camera’s lens release button with your
fi ngers. In this case, use the supplied removal tool.
USING THE REMOVAL TOOL
1. Insert the removal tool through the hole in the camera
adapter which is above the camera’s lens release
button. Orient the tip of the tool as shown below.
2. FOR SONY CAMERAS: Use the tip of the tool
to depress the camera’s lens release button, then
rotate the adapter counter-clockwise.
3. FOR CANON CAMERAS: Position the tip of
the tool between the camera adapter and camera
so it is seated onto the camera’s lens release
button. When properly seated, the button should
be depressed without having to hold the tool with
your fi ngers. Rotate the camera adapter counter-
clockwise.
Place the retaining ring over the camera adapter.
Thread the retaining ring clockwise onto the lens
group cell at the front of the RASA 8. Tighten the
button. Orient the tip of the tool as shown below.
