要通过望远镜观察物体，您必须将其指向正确的位置。Telrad 是一款用于将望远镜指向“正确位置”的瞄准器。
通过 Telrad，您可以看到星图上显示的天空。不是倒置放​​大的一小部分天空，而是“真实的天空”，背景是三个发光的 LED 目标环。

Telrad 助您实现星际跳跃

大环的直径为 4 度，显示的是传统 8x50 寻星镜所覆盖的区域。第二个环的直径为 2 度。小中心环的直径为 1/2 度，勾勒出使用低倍目镜在望远镜中看到的区域。
在星图上选择一个物体，并记下它在可见恒星中的位置。然后将环设置在天空中的那个位置。快速粗略设置会将物体置于寻星镜的视野中。如果没有寻星镜，或者物体暗淡而无法显示，请使用更仔细的设置将物体置于望远镜的视野中。

与寻星镜相比，Telrad 使“星跳”穿越天空变得容易得多。通过练习，您将能够判断物体之间的角距离。单独使用 Telrad 寻找明亮的目标并设置 GoTo 望远镜。要寻找较暗的深空物体，请将 Telrad 与放大寻星镜结合使用。Terad 可以让您接近目标，然后切换到寻星镜以更轻松地看到较暗的物体。

客户不断告诉我们 Telrad 是他们为望远镜添加的最佳配件。我们相信您也会同意这一点。

使用全新高级 Celestron StarPointer Pro 寻星镜，您可以减少瞄准目标的时间，而花更多时间观星。传统的红点寻星镜最初是为射击运动（如气枪和射击运动）而设计的。StarPointer Pro 是由天文学家为天文学家设计的，旨在提供在夜空中定位天体的最简单体验。无论您是业余爱好者还是经验丰富的业余天文学家，您都会欣赏 StarPointer Pro 周到的设计功能。

虽然红点会遮挡您想要的目标，但 Celestron StarPointer Pro 可以投射两个圆形 LED 标线。只需将目标放在圆圈内，即可在目镜中查看。圆圈还可用作星空观测时的测量工具。为了增加便利性，StarPointer Pro 提供了一个 40 毫米光学窗口，视野开阔。StarPointer Pro 可快速连接到任何望远镜，并使用燕尾连接和手指旋钮固定。无需螺丝刀！使用 StarPointer Pro，每次观星都能收获更多。

带支架的 saxon 25.4mm 红点寻星器是一款无放大倍率寻星器，当正确对准望远镜时，它会用发光的红点精确定位您正在观察的物体。与寻星镜不同，红点寻星器会保持天空图像直立且不倒置，因此业余爱好者和专家都可以轻松使用带支架的 saxon 25.4mm 红点寻星器。

适合所有燕尾安装支架。

Tele Vue Sol Searcher 是寻找太阳的安全且简单的方法。

这绝对是安全的，因为您不需要通过 Sol Searcher 查看，只需查看它即可。

光圈充当“针孔”，将太阳的图像投射到 1/4 英寸半透明“屏幕”上。

该屏幕可从任意一侧观看。

只需移动你的望远镜，直到太阳的图像位于屏幕的中心，并且太阳会出现在目镜的视野内。

Sol Searcher 可连接至每个 TeleVue 望远镜的安装环槽（或 TeleVue Ranger 的后部单元槽）。

要与 TeleVue 以外的望远镜一起使用，请使用 #10-32 螺丝安装 Sol-Searcher，或者如果需要，使用 Velcro（不提供）固定。

太阳搜索器说明

The saxon 9x50 Erecting Finderscope (90 degree) is the solution for those who find conventional finderscopes too confusing or disorienting.

The presence of an erecting prism in the finderscope provides you with correct image orientation so that you can look through the finderscope the same you look at the sky.

90 degree viewing angle allows for a comfortable viewing position when looking overhead, and 9x magnification and 50mm aperture give a clear, crisp image.

Simplify your observation sessions with the saxon 9x50 Erecting Finderscope (90 degree).

Hone in on objects with the cross-hair reticle before you observe with your telescope. The 9x magnification and 50mm aperture on the  saxon 9x50 Erecting Finderscope (90 degree) will give you crisp and clear images as you search for stars and planets, while your neck will thank you for comfortable viewing angle afforde by the 90 degree viewing angle as you browse the night sky.

What many will appreciate from the  saxon 9x50 Erecting Finderscope (90 degree) will be that its image orientation is correct (upright, non-reversed). Look through your finderscope the same way you look at the sky.

Fits all dovetail mounting brackets.

The Celestron StarPointer Finderscope is the way to go if you want the easiest way possible to locate an object and center it in your eyepiece.

A red dot finder, unlike an optical finder, has 1x magnification, displays a super wide field of view, and keeps the sky right side up and left-to-right correct, matching what you see with your unaided eyes. An LED creates a red dot, superimposed on a viewing screen, so you simply point the StarPointer to the area or object you wish to observe, look through your eyepiece, and if properly aligned, the area in and around place you pointed the red dot will be centered in the field of view.

If you like the idea of having some magnification, try installing both a red dot and optical finder on your telescope. Schmidt-Cassegrain and EdgeHD telescopes have multiple mounting bracket holes so you can get the best of both worlds. Just make sure to align both of them correctly, and you’ll get the best use out of each of your finders.

How to Align the StarPointer Finderscope

The first time you use your finder, you need to align it. This one-time setup procedure should be done during the day. Take the telescope outside and find an easily recognizable object, such as a streetlight, car license plate, or tall tree. The object should be as far away as possible, but at least a quarter mile away. Move the telescope left and right or up and down so that it is roughly pointing at the object. Look through the telescope using your low power eyepiece and move the telescope until the object you chose lies in the center of the view. Once the object is centered in your eyepiece, turn on the red dot. With your head positioned about a foot behind the finder, look through the round lens of the finder and locate the red dot. Without moving the telescope, use the two adjustment knobs located on the side and underneath the finder. One controls the left-right motion of the dot. The other controls the up-down motion of the dot. Adjust both of these until the red dot appears over the same object you are observing in the eyepiece.

Your finder is now aligned and should not require realignment unless it is bumped or dropped. You can even take the finder off the telescope and reattach it while preserving alignment.
