Too much friction makes it difficult to move the telescope smoothly, while too little allows the tube to drift, especially when changing heavy eyepieces. Sky-Watcher's answer is its patented tension control handle.\u003c\/p\u003e\n\u003cp\u003eIt adds or reduces friction between the tube and the side board, so the tube does not need to be balanced to stay in position. Set it so the tube moves easily when nudged but stays put when you let go, or tighten it fully to lock it. Re-adjust it when you add or remove accessories. The manual recommends installing the tension handle on the same side as the focuser for convenience and leaving the handle on the opposite side slightly loose to give the tension handle full control.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe 44.5-inch Optical Tube and Included Accessories\u003c\/h3\u003e\n\u003cp\u003eThe optical tube is 44.5 inches long with a 7.125-inch outer diameter.

The Dobsonian base arrives flat-packed and is assembled using the included screws and hardware. The process involves connecting the side boards (A1, A2) to board B, with the Sky-Watcher logos outside, then attaching this assembly to the round top board (C). A Teflon pad and a central tube are placed between this assembly and the bottom board (D), and a central bolt secures everything together. Do not over-tighten this bolt, so the base can swivel freely.\u003c\/p\u003e\n\u003cp\u003eOnce the base is built, four cylindrical \u003ca href=\"\/collections\/saddles-and-clamps\"\u003esaddle\u003c\/a\u003e side bearings are attached to the inside of the sideboards.

This is best done in daylight. Point the main telescope at a distant, stationary object at least 500 yards away and center it in the eyepiece. Then, look through the finderscope. Using the two small alignment screws on the finder bracket, adjust the finder until its crosshairs are also centered on the exact same object. These screws work against a spring-loaded knob.\u003c\/p\u003e\n\u003cp\u003eOnce the finder is aligned, achieving focus is done by turning the focus knobs on the focuser. Slowly turn the knobs until the image in the eyepiece is sharp. Refocus when you change an eyepiece or add or remove a Barlow lens. The manual adds that fine refocusing over time is normal, due to temperature changes and flexure, especially before the telescope reaches outside temperature.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eBest Practices for Observing with the 153mm Aperture\u003c\/h3\u003e\n\u003cp\u003eThe manual's observing tips:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSite Selection:\u003c\/strong\u003e Away from city lights and upwind of air pollution, as high as possible, with a dark, unobstructed horizon.

Tripod\u003c\/h2\u003e\n\u003cp\u003eThe Sky-Watcher EQ8-Rh Mount with Pier Tripod is a German equatorial GoTo mount on an adjustable pier tripod, with a 50 kg (110 lb) payload for astrophotography. Its 435:1 worm drive system, powered by 0.9° hybrid stepper motors, achieves a native resolution of approximately 0.03 arc-seconds . The defining feature of the EQ8-Rh is its Renishaw high-resolution incremental encoder on the R.A. axis, which reads 11,840,000 counts per revolution and helps reduce or eliminate the influence of mechanical periodic error. With the included SynScan V5 hand controller, you can navigate a database of over 42,000 celestial objects at slewing speeds up to 3.7° per second.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA 50 kg Payload Capacity\u003c\/h3\u003e\n\u003cp\u003eIt provides a 50 kg (110 lb) payload capacity, rated specifically for astrophotography and excluding the two included 10 kg counterweights.

This component provides a resolution of approximately 0.11 arc-seconds (11,840,000 counts per revolution). This encoder helps reduce or eliminate the influence of mechanical periodic error while the mount tracks an object.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCounterweights and Balancing\u003c\/h3\u003e\n\u003cp\u003eThe EQ8-Rh includes a 2.6 kg counterweight rod and two 10 kg counterweights. Balancing reduces stress on the motor drive system and ensures smooth, accurate operation.\u003c\/p\u003e\n\u003cp\u003eFollowing the manual's procedure, you first balance the R.A. axis by loosening the R.A. clutch and rotating the axis until the counterweight rod is parallel to the ground. You then slide the counterweights along the rod until the mount remains stationary without support.

Controlled entirely over its built-in Wi-Fi via the SynScan Pro app, it gives you access to a database of over 42,900 celestial objects. With the included adjustable aluminum tripod and 0.5 kg pier extension, the complete system weighs about 4 kg (8.6 lb) and runs on 8 AA batteries or an external 7.5 to 14 V DC supply.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDC Servos, 6480 Gear Ratio, and Freedom Find Encoders\u003c\/h3\u003e\n\u003cp\u003eAt the core of the AZ-GTi are DC servo motors that drive both axes through a 6480 gear ratio, delivering a pointing resolution of 2,073,600 counts per revolution, or 0.625 arc-seconds. For precise GoTo slewing and tracking, fully tighten the clutches for all motor-driven use, which gives the best pointing accuracy.
