Over time the grease in the central pivot shaft hardens to restric the rotation of the focusing wheel. Heat from a hair dryer combined with a little WD-40 can ustally re-soften the grease permitting the wheel to turn slightly. Working the wheel back and forth over a short period of time should get it to work again easily.

Steward, this is Joe Lalumia-- I have seen your post on various forums. The 14 inch is different from the other smaller LX200 scopes.

Probably Dr. Clay, and or Andrew on the Yahoo Group LX200 forum will know the answer because they service these scopes.

Post a message there (register for free) and one of them will answer you about that very nice scope.

Clear Skies!

You are OUT of focus -- turn the focus knob until stars are POINTS of light NOT DONUT HOLES!

The disk with a dark center MEANS it is not in focus. Just TURN THE KNOB. Point the scope at the moon and try again.

the front should pop off, remove what screws you can find, the rest are snaps.. really tough ones.. let me know if you need further assistance.

Out of focus


Assuming you are focussing correctly. When binoculars are out of collimation the most usual effect is double vision as the optical axis do not line up. The only thing you can do is to take them to a binocular repairer. The problem is the cost. Proper repair need the use of a device known as a collimator and it is a laborious task to do it properly. Your binoculars do not carry a high monetary value and a proper repair will cost more than a new binocular of similar specs. Porro prism binoculars mostly have the objective lenses set further apart than the eyepieces. This holds true except for reverse porro prisms which are the other way round. Roof prisms have both the front and rear lenses inline.
Make sure when you focus that the first eye you use to focus with is the one where the eyepiece does not have its own focus ring (dioptre). The dioptre adjustment is on either the left or the right depending on the brand. That eyepiece should be left alone until you have focused using the center ring. Then leave the center ring alone and focus the eyepiece that has the adjustment ring.

Focus?


The C8 optical tube has a very large focal range. It should be capable of focusing on objects from 15' to infinity. To focus on object at infinity you have to move the primary mirror foward. You do this by rotating the focus knob CCW. Rotate the knob CCW until it comes toa stop them slowly bring the mirror back by rotating the knob CW while viewing the object. It will snap to focus so don't move too fast yor you'll miss it.
