Need some colour planetary filters to enhance your viewing experience?

Why not get a set of four with the saxon 1.25" Colour Planetary Filter Set?

The saxon 1.25" Colour Planetary Filter Set is a great addition for lunar and planetary observing. They help increase image contrast and resolution on the Moon and planets as well as reduce glare from the full or near-full Moon.

The set comes in four colours of Yellow (#12), Red (#23A), Neutral Density (#96ND) and Blue (#80A). 

Quickly and conveniently collimate your telescope with the saxon 1.25 Laser Collimator!

Quickly guides you towards the precise alignment of your telescope, this aluminum laser collimator has a bulls-eye target that allows you to easily adjust the telescope's primary mirror by tweaking the adjustment screws. 

Collimation is successful once the laser beam hits the bulls-eye.

Proper collimation will mean sharper views and better astro photos by better the best from your telescope's optics.

This will work with all Newtonian style reflecting telescopes and also suits M42 and M48 threads.

Enhance your stargazing experience with the Saxon 1.25" Moon & Skyglow Filter, an essential accessory for amateur astronomers and astrophotographers. This filter is designed to fit any 1.25-inch telescope eyepiece, significantly improving lunar observations by reducing glare and boosting contrast, revealing craters and lunar seas in exceptional detail.

Ever tried look at the Full Moon through a telescope? You'll know just how bright it can be!

The saxon 1.25" Moon Filter helps reduce glare and increase the contrast of the Moon allowing you to see the fine details on craters, mountains and across the Lunar plains, called Mare.

The Saxon 10" DeepSky CT Dobsonian Telescope （254/1200） features a powerhouse telescope with amazing light-gathering capabilities that's easy to use and transport.

This telescope is the retractable twin to the full-tube Saxon 10" DeepSky Dobsonian Telescope and comes with the same specs of 254mm aperture and a focal length of 1200mm. Featuring a collapsible truss-tube dobsonian design, the optical tube can be retracted into a shorter length and locked down to ensure secure and easy transportation. This scope also comes with a paraboloidal primary mirror to eliminate spherical aberration allowing you to see wide-field views of the Moon, constellations and deep sky objects such as the Great Orion Nebula.

Assembly of the telescope requires no additional tools. You'll be pleased with how easy it is to use the Saxon 10" DeepSky Collapsible Dobsonian Telescope with its Dobsonian mount. Simply swivel the telescope to the direction of your intended object and look through the eyepiece. This scope's Teflon bearing system in both axes with tension control handle means you'll be able to smoothly move your telescope to a precise location.

What is a Dobsonian telescope and why the tension control handle?

A simple, elegant form of an alt-azimuth mount made to carry a Newtonian reflector was popularized by John Dobson in the late 1970's. The Dobsonian mounted telescope is popular among amateur astronomers and telescope makers because of its simplicity. In its simplest form, the Dobsonian mount consists of a box which allows the optical tube assembly to pivot in altitude, while the box itself is swivelled on a base in azimuth.

The Dobsonian mount usually relies on the friction between the side bearings on the optical tube of the telescope and a frictional material on the saddle to hold the optical tube in place. If there is too much friction, the telescope is difficult to move to center an object in the filed of view. If there is too little friction, the telescope will not sty where it is positioned. This makes stabilizing the optical tube of the telescope difficult when using a Dobsonian mount, especially when accessories, such as a finderscope or an eyepiece, are added to the optical tube. As long as the amount of friction is at an appropriate level, and therefore stabilization of the optical tube is achieved, the telescope can remain in its desired position to view an object and maintain its position even when the mount is rotated.

The devices for stabilizing a telescope on the Dobsonian mount currently available include: a sliceable weight to counter balance the weight of the telescope, a friction lock that must be adjusted to inhibit movement of the telescope, and a spring attached between the telescope tube and mount to aid in stabilization.

These devices are inconvenient to use because they do not provide a simple and user-friendly way to adjust the friction. The objective of the saxon Tension Control Handle invention is to provide a tension adjuster that users can easily turn to add or reduce tension, thereby increasing or decreasing the friction between the optical tube and the sideboard of the mount.

By providing such a tension adjuster, the telescope does not need to be balanced in order to stay in position. The tension adjuster can be tightened such that the optical tube can stay in a position but can still be moved when prompted to adjust the position of the optical tube. Alternatively, the tension adjuster can be completely tightened to lock the optical tube in position.

什么是多布森望远镜以及为什么要使用张力控制手柄？

20 世纪 70 年代末，约翰·多布森 (John Dobson) 发明了一种简单而优雅的地平式方位角支架，用于承载牛顿反射镜。多布森式支架望远镜因其结构简单而受到业余天文学家和望远镜制造商的青睐。最简单的多布森式支架由一个盒子组成，该盒子允许光学管组件在高度上旋转，而盒子本身则在底座上以方位角旋转。

多布森式支架通常依靠望远镜光学管上的侧轴承与鞍座上的摩擦材料之间的摩擦力来将光学管固定到位。如果摩擦力太大，望远镜很难移动到视野中心。如果摩擦力太小，望远镜将无法停留在原位。这使得使用多布森式支架时很难稳定望远镜的光学管，尤其是在光学管上添加了寻星镜或目镜等附件时。只要摩擦力大小合适，光学管就能稳定，望远镜就可以保持在所需位置来观察物体，即使在支架旋转时也能保持其位置。

目前可用的稳定多布森式支架上望远镜的装置包括：一个可切片的重物，以平衡望远镜的重量，一个必须调整以抑制望远镜移动的摩擦锁，以及一个连接在望远镜筒和支架之间以辅助稳定的弹簧。

这些装置使用起来很不方便，因为它们没有提供简单且用户友好的方法来调整摩擦力。saxon 张力控制手柄发明的目的是提供一种张力调节器，用户可以轻松转动它来增加或减少张力，从而增加或减少光学管和支架侧板之间的摩擦力。

通过提供这样的张力调节器，望远镜无需保持平衡即可保持在原位。张力调节器可以拧紧，这样光学管就可以保持在原位，但在需要调整光学管的位置时仍然可以移动。或者，张力调节器可以完全拧紧以将光学管锁定在原位。
