 | EQ6 Deluxe Super Heavy-Duty Equatorial Mount Ref: OV-740
OPTICAL VISION The Sky-Watcher EQ6 equatorial mount is the first of its kind, and is top of our range of equatorial mounts. It is a precision instrument capable of carrying massive payloads (up to 25Kg) but at the same time is very reasonably priced. The mount is excellent for visual observations and short-term unguided CCD imaging with most telescopes of conventional design. It will easily handle refractors up to 8"/200mm and classic Newtonians up to 14"/350mm in aperture. The EQ6 has a black powder coat finish and weighs in at 17Kg. The equatorial head features engraved aluminium setting circles and a latitude scale, a polar finder scope holder and polarscope, a bubble level, large R.A. and DEC. locking clamps, built-in dual axis motor drives and retractable counterweight shaft and counterweight. Two counterweights are supplied, each weighing 5.4Kg. The dual-axis motor drives are operated by a hand controller with a switch for both Northern and Southern hemisphere operation with slewing speeds of 2x, 8x and 16x the sidereal rate. The tripod is made from 2" diameter stainless steel legs, making for a very sturdy system. The EQ6 (without telescope) adjusts from 1069mm in its lowest position to 1544mm with the tripod legs fully extended. The height of the mount (excluding tripod) is 406mm. The EQ6 accepts generic dovetail bars made by Sky-Watcher and many other companies.

 | CGE Equatorial GoTo Mount Ref: DH-91524
CELESTRON The CGE German Equatorial mount offers numerous design advantages: Portability – Set up and transportation of the CGE telescopes is made easy by separating the CGE instruments into smaller, easy-to-carry components. Unlike fork arm mounted telescopes, the CGE’s optical tubes can be quickly removed from their mounts making even the CGE 1400 easily assembled by only one person. Stability – Recognized for superior stability, German Equatorial mounts place the center of gravity directly over the tripod legs and can be easily polar aligned without the use of an optional equatorial wedge. This proven design reduces the “tuning fork” vibration that can be associated with undersized fork mounts. An improved Super HD Tripod supports the CGE mount. This fully extendable tripod is made from the finest cold rolled carbon steel and can be raised to a height of 50". The tripod uses a dual leg support for maximum rigidity with an upper leg brace to provide an outward preload and a lower leg brace providing inward tension. Balance – CGE equatorial mounts can easily be balanced in both axes. Simply simply sliding the counterweight for Right Ascension and moving the optical tube along its dovetail mounting for Declination accomplish balancing the weight of camera equipment and other visual accessories. This means that no additional weight needs to be added to balance the telescope when additional accessories are added. Clearance – CGE mounts support their tubes at a single contact point allowing the tube to move freely around its polar axis without making contact with the telescope’s mount. This is particularly useful when adding photographic and CCD instruments that extend from the rear of the telescopes. GPS Compatible – All CGE mounted telescopes are compatible with Celestron’s CN-16 GPS accessory (#93967). Combine the GPS and built-in Hibernate mode and these telescopes will keep track and remember their exact location and time without having to enter the information into the hand control. Other CGE Capabilities Include:Mechanical Features - Carbon Fiber Tube – Strong and lightweight with 1/4 the thermal expansion of an aluminum tube on the 8" and 11" models. Scratch and dent resistant.
- CNC machined aluminum and stainless steel components
- Autoguide port, PC port and auxiliary ports located on the electronic pier.
- Strain relief power cord cable protection
- Backlit power switch
- Drive Motors – Made in the U.S.A., Pittman® LO-COG™ brush-commutated DC motors offer smooth, quiet operation and long life. The motor armatures are skewed to minimize cogging which is required for low speed tracking. Windings are resin impregnated for greater reliability in incremental motion applications.
- Precision Bronze Worm Gear – 32 pitch, 5.625" pitch diameter, 180 tooth bronze gear manufactured in the U.S.A. by W. M. Berg, Inc. Manufactured to AGMA Quality Class 10 standard, which minimizes total composite error and backlash.
- Bearing and Shaft – Stainless steel worm shaft has 0.4375 pitch diameter and is preloaded with two ball bearings. The worm is made from a single piece of steel (rather than a two-piece worm-and-shaft assembly) to minimize run-out, which is a source of periodic error.
- 4 point RA clutch system for no-slip pointing precision
- Schmidt-Cassegrain mechanism that moves the primary mirror to adjust focus is supported by two pre-loaded ball bearings, minimizing the “mirror flop” typical of bushing focus mechanisms.
- Latitude range: 10º to 60º northern or southern hemispheres
- Maximum payload: 65 lb.
RA and Dec Axis - 1" solid ground stainless steel shaft
- Two preloaded 0.9835" I.D. x 2.047" O.D. tapered roller bearings
- One 3.543" I.D. x 4.724" O.D. thrust bearing (RA Axis)
- 180 tooth, 5.625 pitch diameter enveloping bronze gear preloaded to maintain gear mesh when clutch tension varies, manufactured to AGMA 10 quality by W.M. Berg
- 0.4375" diameter precision 303 stainless steel worm manufactured to AGMA 10 quality
- Four point RA clutch system pre-loading a 4.65" stainless steel disk for no-slip drive and pointing precision
- One 2.500" I.D. x 3.250" O.D. thrust bearing (Dec Axis)
Tripod - Adjustable height: 36" to 50"
- Leg material: cold rolled carbon steel
- Upper leg diameter: 2.75"; lower leg diameter: 2.375"
Electronic and Software Features - GoTo system is precision accurate to 1.5 arcminutes
- 40,000+ object database with 400 user-defined objects. Features include: Compass Calibration, Polar Alignment routine, Database Filter Limits, Hibernate, Auto North and Level, Quick Align, and user-defined slew limits.
- Hibernate – maintains alignment even while powered down.
- Polar alignment routines for Northern and Southern hemispheres.
- Filter limits – displays only objects above the horizon.
- Permanent programmable periodic error correction (PEC) – corrects for periodic tracking errors inherent to all worm drives.
- Smooth ramping of slew motors to reduce wear on the drive train.
- Home sensors on R.A. and Dec axes.
- Fail-safe slew limit switches in R.A.
- Real-time clock – maintains time even when powered down.
- 12VDC Servo Motors with integrated optical encoders with 0.11 arcsecond resolution.
