Filter/Imaging Chip Re-assembly
Here is the diagram again showing
the components of the filter/imaging chip assembly. Use it for
reference in the steps below.
31. Place Low-pass filter 1 into the Baader
replacement glass assembly completed in Step 30. Make sure for
the next steps that all optical surfaces are clear of dust using
a blowers bulb, camel hair brush or a microfiber lens cleaning
For the FULL
SPECTRUM MOD instead of re-installing the Low-pass filter 1, install
the Astronomik MC clear class. It is a little thicker than the
original Low-pass filter 1 but the metal frame in the next step
can still be used to secure it in place. As an option, you can
transfer the black gasket from Low-pass filter 1 and place it
on the the Astronomik MC clear glass in the same position, but
some may prefer to leave the gasket off.
32. Place the "support material"
metal frame over the above assembly and push down on all four
corners until it snaps into place. Note the orientation of the
metal frame in the Step 33 photo. Be careful not to scratch the
33. Make sure all optical surfaces are clean.
Place the plastic filter assembly onto the CMOS imaging chip metal
frame. Note there are two small black pins on the back of the
plastic filter assembly that mate into two holes in the metal
CMOS frame. Do this carefully to avoid contacting the imaging
area of the CMOS chip with any other object, such as the sticky
tape gasket that will seal the unit. Insert three screws in the
holes shown. ***550D

34. The filter/CMOS assembly is now completed
and ready to be placed back into the camera body.

how this is done.
