SkyWatcher Quattro 300Q on EQ8-RH Reflector Telescope with Pier Tripod

The Quattro imaging Newtonian is an affordable, large-aperture astrograph, ideal for users searching for a fast imaging system that will work for both astrophotography and visual astronomy. Boasting a swift f/4 focal ratio, this astrograph is can produce an exposure 6x faster than the average 8-inch f/10 Schmidt Cassegrain telescope. Although designed as an imaging optical tube, these Newtonians also produce bright and detailed viewing for visual astronomy.

Like all Sky-Watcher reflectors, the Quattro imaging Newtonian features borosilicate mirrors coated with Sky-Watcher's proprietary Radiant Aluminium Quartz (RAQ), producing 94% reflectivity. The tube is constructed with rolled steel, then coated with Sky-Watcher's signature glossy metal-flake Black Diamond finish. The OTA uses an oversized secondary mirror providing greater illumination for DSLRs and CCDs using full-frame sensors, and an optional coma corrector is available for those who want to take their imaging to the next level.

Included with the Quattro imaging Newtonian is a 10:1 dual-speed 2-inch Crayford-style focuser, 1.25 and 2-inch eyepiece adapter, a 9x50 finderscope, tube rings, and a D-style dovetail plate.

Built-in Cable Management

USB hub (4 ports)

2.1mm Power port (3 ports)

3 serial ports on the back of the saddle

The EQ8-Rh features built-in cable management. This removes cable drag from hanging cables and reduces the risk of cables getting caught during imaging session. This capability also improves the mounts capabilities for remote use.

The built-in USB hub allows you to simply plug in your camera, guider, filter wheel and other USB accessories into the hub below the saddle plate and connect them using a single USB cable plugged into the rear of the mount. No more tangled mess of cabled hanging or need for multiple cables running around the mount.

Another addition to the cable management system is the three built-in 2.1mm ports situated next to the USB hub. This allows your accessories to also be powered through the mount. This reduces the need for multiple power adapters and other accessories. The ports can be run off of a single power source providing a cleaner set up and less cables.

On the gear of the saddle are three serial ports for various accessories such as ST4 guide cables and other serial based accessories. Like the rest of the cable management this reduces the hanging cables and provide a neat connection to the mount.

Motor Positioning

EQ8-Rh feature improved balance from their predecessor with redeposited motor housings. This improve the mount's balance over all.

Belt Drive

Both mounts feature belt drive on both the RA and Dec axis. This allows for smoother guiding and reduced backlash.

Auto-Home

EQ8-Rh feature built-in homing sensors. This allows the mount to know its positioning more accurately from its start positioning.

Improved Clutches

The EQ8-Rh models feature improved clutches allowing for sturdier lock under heavy loads. Simply use the large levers to engage or disengage the axis of choice. The clutch lever are larger than the original EQ8 making it easier to adjust with gloves.

PC Direct Connect

EQ8-Rh also feature the new PC direct connect feature. Now you can easily connect your mount to your computer without the need of a hand controller. When paired with the SynScan Pro app. for Windows the mount can be aligned and controlled direct from a PC. This makes imaging refined and easier, especially for those with permanent set ups.

EQ8-Rh On-Axis Encoder

The EQ8-Rh takes a step further with all the listed features above but adds a higher level of precision. The Rh (h for High Res.) features an on-Axis Renishaw TONic incremental, 11.8 million tick, encoder on the RA axis. This allows the mount to have extremely precise tracking and guiding for long exposure imaging. With the encoder built onto the RA axis this removes periodic error to nearly zero in RA with an accuracy of 0.11 arc-seconds! The EQ8-Rh offers a pro level mount for the series astro imager.
