8 CHECK AND ADJUSTMENT
Pointers on the Adjustment
1
Adjust the eyepiece of the telescope properly prior to any checking
operation which involves sighting through the telescope.
Remember to focus properly, with parallax completely eliminated.
2
Carry out the adjustments in the order of item numbers, as the
adjustments are dependent one upon another. Adjustments carried
out in the wrong sequence may even nullify previous adjustment.
3
Always conclude adjustments by tightening the adjustment screws
securely (but do not tighten them more than necessary, as you may
strip the threads, twist off the screw or place undue stress on the
parts).
Furthermore, always tighten by revolving in the direction of
tightening tension.
4
The attachment screws must also be tightened sufficiently, upon
completion of adjustments.
5
Always repeat checking operations after adjustments are made, in
order to confirm results.
Notes on the Tribrach
1
If any leveling screw becomes loose and slack or if collimation is
unstable due to the looseness of leveling screws, adjust by
tightening the adjusting screws (in 2 places) installed over each
leveling screw with a screwdriver
2
If there is any slack between the leveling screws and the base,
loosen the set screw of the holding ring and tighten the holding ring
with adjusting pin, until it is properly adjusted. Re-tighten the set
screw on completing the adjustment
