Finding the right telescope can offer greater viewing potential.
The Bushnell Voyager 565 x 60 telescope offers first-rate optical quality and mechanical construction to get a clear view of faraway objects in the sky. This is a refracting lens telescope (where one looks down into the eyepiece) that is set on an aluminum tripod and is adaptable to cameras. The telescope's unique configuration of the Penta mirror technology, Finderscope, eyepieces and Barlow lens allow greater and easier viewing capacity.
Penta Mirror
The Penta Mirror technology is exclusive to Bushnell. It offers a 90-degree viewing angle similar to diagonal mirrors but, more importantly, allows correct views of images. This means that instead of seeing images reversed -- where you have to move to the right to view an image on the left -- you can naturally move to the left to locate an object. Locating objects to view as they appear in the night sky is so much easier than fumbling trying to locate an object that isn't where it appears to be. The Penta Mirror, which is shaped somewhat like a half-circle, is placed into the end of the telescope-focusing tube, and the eyepiece is placed into the other end.
The Eyepiece
The Bushnell Voyager comes with three eyepieces -- 8 mm, 12.5 mm and 20 mm. These are small silver cylinders that have a black viewing end and screw into the telescope on the other end. Always start with the lowest power. The eyepiece can be inserted into the rear of the Penta mirror assembly. A formula to determine the power of each eyepiece is to divide the eyepiece number by the telescope's objective lens focal length, which is 750 mm. So 750 divided by 20 mm = 38x, or 38 power.
Barlow Lens
Double or triple the power of the telescope with the Barlow lens. It is a small cylinder that comes with the telescope with the lens on one end and a mount on the other that screws into the telescope. It should be placed between the focusing tube and the Penta Mirror. Using the Barlow lens with the Penta Mirror and eyepiece effectively doubles the magnification power over the Barlow lens and eyepiece alone. This means the power would go from 38 with eyepiece alone to 114 with Barlow lens and eyepiece to 228 power with all three configured.
Finderscope
The red dot Finderscope is used to locate objects in the night sky by aligning them with the red dot. The Finderscope is a small cylinder that slides onto the Finderscope mount. To use it, look through the main telescope tube at low power to find a well-known object. Then look through the Finderscope and tighten the adjustment wheels at the rear and left side of the Finderscope until the red dot in the cross hairs is centered on the same object you saw in the main telescope tube. Always start with the lowest-power eyepiece, as this will give a brighter image and a wider view field, making it easier to find the targeted object.
