  • Page 37: Check And Adjustment

    CHECK AND ADJUSTMENT ● Pointers on the Adjustment 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. Carry out the adjustments in the order of item numbers, as the adjustments are dependent one upon another.

  • Page 38: Checking /Adjusting The Plate Level

    8.1 Checking /Adjusting the Plate Level Adjustment is required if the axis of the plate level is not perpendicular to the vertical axis. ● Check Place the plate level parallel to a line running through the centers of two leveling screws, say, A and B. Use these two leveling screws only and place the bubble in the center of the plate level.

  • Page 39: Checking And Adjusting The Circular Level

    8.2 Checking and Adjusting the Circular Level ● Checking Carefully level the instrument with the plate level only. If the bubble of the circular level is centered properly, adjustment is not required. Otherwise, proceed with the following adjustment. ● Adjustment Shift the bubble to the center of the circular level, by adjusting three capstan adjustment screws on the bottom surface of the circular level, with the accessory adjusting pin.

  • Page 40: Adjustment Of The Vertical Cross-Hair

  • Page 43 ● Adjustmen Unscrew the cross-hair adjustment section cover. Find Point D at a point between Points C and B, which should be equal to 1/4th the distance between Points B and C and measured from Point C. This is because the apparent error between Points B and C is four times the actual error since the telescope has been reversed twice during the checking...
