GETTING#497 HANDBOXSTARTED

Because your telescope has so much magnification, its field of view is very small. This can make it hard to know exactly where your telescope is pointing by simply looking at it. To help you point the telescope quickly and accurately, for terrestrial targets or GO TO pointing, the LT Series has a 1X Red Dot Viewfinder.

The Red Dot Finder will aid you in pointing your telescope easily. It works much like a fighter pilot’s heads-up display. To turn on the Red Dot Finder, carefully rotate the power switch until you feel it click on. Turning further clockwise will increase the dot brightness. Adjust the dot to the minimum brightness where it can be easily seen. This will extend its battery life and make it easier to see faint stars in the background. Look through the finder’s glass window. You will see a red dot superimposed on your view. Using the direction keys on the handbox, move the telescope until the red dot is on the target you want to view in the eyepiece. As you get close to your target, select a moderately low speed, like speed 5, and move the scope to center your target as you look through the eyepiece. This a great way to get used to finding the movement keys without removing your eye from the eyepiece.

The Red Dot Finder has been aligned at the factory, but you may need to touch-up the alignment from time to time. To do this, look through the eyepiece of your scope and using the hand controller center a distant object. Now turn on the Red Dot Viewfinder and adjust the brightness so you can see the red dot. Look through the sight as pictured above.

Adjustment

Screws

Now, without moving the telescope, adjust the indicated thumb screws until you have put the red dot on the object at which you were looking. It’s that simple.

Now use the hand controller to put the laser dot on a new target. Check to see that the desired target is in the eyepiece and adjust the focus knob until the object is in focus.
