Changing the filter:
To change the filter, loosen the 6 grub screws on the side of the unit by means of the 1.5mm
Allen key supplied. Then tilt the body of the
Protective T-ring
carefully forward and take out the
built-in 50.8mm filter and the Delrin temperature compensation ring. Now insert another 50.8mm
or 50.4mm filter and place the temperature compensation ring on top of it. Now put either the
S52/M48 ring or the S52/2" connector socket into the body and fasten the unit together by
means of the 6 Allen screws. Here, S52 is a description of the diameter of the retaining cone
which is clamped in place by means of the 6 screws.
Alternatively, you can install a Baader 2" low profile filter. This is screwed in from the inside into
the M48 thread in the main body of the T-ring. After this - as previously described - either the
S52/M48 ring and the M48/T-2 or the S52/2" connector socket can be inserted and tightened up
by means of the 6 Allen screws.
The FILTER SHOULD ‘RATTLE’! This is not a defect. The slight looseness of the filter in the
mounting is very small and serves to protect the filter against stress. This minimal play will not
affect the image position.
