equatorial mount with clock drive

But this does require quality craftsmanship and accurate polar alignment. The clock drive will keep the mount in synchronization with any fixed objects in the sky. The telescope itself was dusty and wet, but the mount was in a good shape, just the driver electronics for the motor were missing. Skywatcher R.A. Motor Drive For EQ-1 With Multi Speed Handset. The supplied simple RA clock drive is excellent for this price range. In its standard form, the equatorial mount’s polar axis is angled to aim at the north celestial pole, near Polaris, the North Star. This device is called a clock drive. Clock drive mechanism in the pier of the German equatorial mount for the 8-inch refracting telescope at Aldershot Observatory. Description. Closely following this apparent motion allows the telescope to stay fixed on an object for long durations. The sorts of clocks used to drive mounts were similar to "Church Tower" clocks - capable of holding a three foot long minute hand still on a windy day!! This is the rate of the apparent motion of the sky. (1) Can be fitted to any of our telescopes supplied with the EQ3-2 equatorial mount. While quite honestly, I don't think that this mount can compete against the more expensive telescope mounts available for dedicated astronomy, it did think that it was useful for me to … In astronomy , a clock drive (also known as a field rotator) is a motor-controlled mechanism used to move an equatorial mounted telescope along one axis to keep the aim in exact sync with the apparent motion of the fixed stars on the celestial sphere . For those interested in prime-focus astrophotography, a computerized equatorial telescope mount is essential. Drive provides regulated sidereal-rate tracking in right ascension. Provides multi-speed (1x/2x/8x) motor tracking of the R.A. axis. After some poking and googling I was able to determine that the mount uses a bipolar stepper motor to compensate for Earth’s rotation. For a total cost of $79.80. Variable-speed dual-axis motor drive for NEQ3 (EQ3, EQ3-2) mount. Click here for more information and to buy from eBay. threaded hole in motor drive mounting plate aligns with the elongated hole near the top of the recess. The hand controller can be used as a correction for long exposure photographs. The telescope tube is brass and its equatorial mount is a mix of gunmetal and brass. Technically speaking, an eq mount with smooth, accurate motion and an accurate clock drive and which is properly polar aligned will track in such a way as to keep an object in the eyepiece all night long. Expert Support International Shipping Plug into the AC outlet, and the clock drive will work smoothly. The solution is an equatorial mount with motorized drive (what used to be called a clock drive) to precisely counteract the Earth’s rotation. Clock Drive For skywatcher Telescope Equatorial Mount EQ2. This is the process of aligning the mount with the north or south celestial pole, which allows the mount to spin on the same axis that the Earth does. 1.25-inch Eyepiece #1/ 20 mm, 33x mag. Fred Tretta published a paper in the Riverside Telescope Makers Conference at 1980 that detailed the I would like to find a non-computerized equatorial mount with a clock drive that could carry a 30 pound load. Hand controller has 2x and 8x speeds and pause mode. With an optional Clock Drive and either a Piggyback Camera Mount or a telescope with Camera Adapter the owner is equipped to pursue introductory astrophotography producing results that most amateurs would be proud to put on their wall. Clock-driven equatorial platforms are sometimes used in non-tracking type mounts, such as altazimuth mounts. The original inventor of the clock drive is unknown, being an idea that was tried in several ways throughout history. mpn: 1600-1, short description: title: TASCO 1600-1 Clock Drive Telescope Equatorial Mounts Tracking 046162142189, Brand: TASCO, Mpn: 1600-1, Upc: 046162142189, sku: 2818970168601411, brand: tasco, category: camera & photo > accessories > telescope parts, gtin/upc: 046162142189, sku: 2818970168601411, An equatorial mount telescope is one equipped with a clock drive that keeps the equatorial axis of the Earth, known as its right ascension, in synchronized motion with the perpendicular axis of the sky, known as its declination. Add right ascension (RA) tracking capabilities to any Celestron AstroMaster or PowerSeeker equatorial telescope, or any set-up that uses a Celestron CG-2 or CG-3 equatorial mount. Excellent for tracking in RA. The maximum distance the weights can be placed on the counterweight rod is 0.33 metres, therefore the maximum torque that a motor would ever need to turn the mount is 11.5x2x0.33 = 7.59 Nm. Clock drives can be light and portable for smaller telescopes or can be exceedingly heavy and complex for larger ones such as the 60-inch telescope at the Mount Wilson Observatory. Clock-driven equatorial platforms are sometimes used in non-tracking type mounts, such as altazimuth mounts. See below for similar items. In order to align the mount properly, you will either need to manually turn a slow-motion knob on the right ascension axis or by adding a clock drive. We’re going to show you how to build a motorised equatorial platform able to track the sky for an extended period (approximately one hour) before you need to adjust your scope. Answer (1 of 2): Hello, What makes a Dobson scope is the simple az/alt base for it. Clock drive for Celestron CG3 Mount. Enjoy motorized tracking of celestial objects with this precision mini motor for the Orion EQ-1 equatorial mount. This also includes the clock drive for tracking against the night sky. Also included are two (2) 6 pound counterweights and an auxillary counterweight shaft. An equatorial mount makes for easier tracking. Equatorial mounts are heavier and require a longer setup time than altitude azimuth mounts. When observing the sky with a properly aligned mount, it compensates for the Earth's rotation, keeping celestial objects centered in the field of view. For polar-aligned equatorial mounts, the motor drive will correct for earth's rotation. Petra Equatorial Mount Includes: PETRA EQUATORIAL MOUNT Includes: 1" Solid Stainless Steel Shaft Equatorial Mount, Bearing Housings and Equatorial Head CNC Machined from 6061-T6 Aircraft Aluminum, R.A. & Dec Setting Circles, R.A. & Dec Axes Locks, Adjustable Height Metal Tripod, Spring Loaded Quick Release Anti-Backlash Declination Tangent System … This Orion Electronic Telescope Motor Drive offers sidereal rate tracking control in right ascension. Design a German Equatorial Mount Jeff Beish INTRODUCTION After a question from a planetary observer/telescope maker was posed to me concerning telescope mounts a reference came to mind that may interest other telescope makers. Attached Focuser/ Manual. Any streak is not a star and is moving fairly quickly. A quick tour of my Tasco 302012 Telescope including its clock drive and electric focuser. Requires drift track 90 deg to columns in CCD. Any "blinking" points are not stars and are moving slowly. Orion 6" f4 Reflector telescope with equatorial mount, clock drive, telrad finder, dew shield, eyepiece case and 2 eyepieces. The internal motors allow the telescope mount … How to Build an Equatorial Mount for Long Exposure Astrophotography: Last Fall (2011) I took full advantage of the fantastic sabatical policy where I am employed. An equatorial mount has one rotational axis parallel to the Earth’s axis of rotation. This design allows the attached instrument (your camera or telescope) to stay fixed on a celestial object by driving one axis at a constant speed. The equatorial axis is known as right ascension, while the perpendicular axis is called declination. Included hand controller features 2x speed, 8x speed, and pause mode. This is an orion table top min eq German equatorial mount with included clock drive and hand controller.
