Details

Recognized For Superior Stability
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.

CGE Equatorial Mounts Can Easily be Balanced on Both Axes
Balancing the weight of camera equipment and other visual accessories is accomplished by simply sliding the counterweight for Right Ascension and moving the optical tube along its dovetail mounting for Declination. This means that no additional weight needs to be added to balance the telescope when additional accessories are added.

Clearance For Accessories
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 mounts are compatible with Celestron's CN16 GPS accessory (Item #93967). Combine the GPS and built-in Hibernate mode and these mounts will keep track and remember their exact location and time without the need to re-enter the information into the remote hand control.

Messier 82 the Cigar

Messier 82 the Cigar

Messier 82 (also known as NGC 3034 or the Cigar Galaxy) is the prototype[3] nearby starburst galaxy about 12 million light-years away in the constellation Ursa Major. The starburst galaxy is five times as bright as the whole Milky Way and one hundred times as bright as our galaxy's center.[3]

In 2005, the Hubble revealed 197 young massive clusters in the starburst core.[3] The average mass of these clusters is around 2�105 M⊙, hence the starburst core is a very energetic and high-density environment.[3] Throughout the galaxy's center, young stars are being born 10 times faster than they are inside our entire Milky Way Galaxy.[4]

Messier 46 Ngc 2438

Messier 46 Ngc 2438

Messier 46 (also known as M 46 or NGC 2437) is an open cluster in the constellation of Puppis. It was discovered by Charles Messier in 1771. Dreyer described it as "very bright, very rich, very large." M46 is about 5,500 light-years away with an estimated age on the order of several 100 million years.[1]

The planetary nebula NGC 2438 appears to lie within the cluster near its northern edge (the faint smudge at the top center of the image), but it is most likely unrelated since it does not share the cluster's radial velocity.[1][2] The case is yet another example of a superposed pair, joining the famed case of NGC 2818. [3][1]

M46 is about a degree east of M47 in the sky, so the two fit well in a binocular or wide-angle telescope field.

Eskimo Nebula (NGC 2392)

Eskimo Nebula (NGC 2392)

The Eskimo Nebula (NGC 2392), also known as the Clownface Nebula,[4] is a bipolar[2] double-shell[5] planetary nebula (PN). It was discovered by astronomer William Herschel in 1787. From the ground, it resembles a person's head surrounded by a parka hood. In 2000, the Hubble Space Telescope produced an image of it. From space, the nebula displays gas clouds so complex that they are not fully understood.

Its inner shell measures 18″ � 15″ and is bright and elliptical and marked on its south rim by two blister-like protrusions. Its outer shell is nearly circular measuring 24″ radius and contains a set of complex low-ionization features. It is observed to have high-dispersion spectra of optical nebular lines which indicate a fast collimated outflow with a velocity along our line of sight of nearly 200 km/s producing dynamic interaction with nebular material. As of 2003, it is estimated to be only ≥1060 years old. The earth's perspective is almost along its axis of symmetry. Its knots have a highly developed symmetry along a radius vector from the PN's central star, except their tails are somewhat irregular. The tails are well developed and frequently of a discernible optical thickness in the visual spectrum. The knots are bright rimmed and have low ionization (as compared to those found in NGC 7293) which indicates their location being inside the ionized zone yet close to the boundary. The knots' heads have local photoionization fronts which appear as bright cusps. At the cusps, the knots become optically thick to Lyc photons from the central star.

It is surrounded by gas that composed the outer layers of a Sun-like star. The visible inner filaments are ejected by strong wind of particles from the central star. The outer disk contains unusual light-year long orange filaments.

NGC 2392 lies about 3000 light-years away and is visible with a small telescope in the constellation of Gemini.

Messier 1 The Crab Nebula

Messier 1 The Crab Nebula

The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The nebula was first observed by John Bevis, and corresponds to a bright supernova recorded by Chinese and Arab astronomers in 1054. Located at a distance of about 6,500 light-years (2 kpc) from Earth, the nebula has a diameter of 11 ly (3.4 pc) and expands at a rate of about 1,500 kilometers per second.

At the center of the nebula lies the Crab Pulsar, a rotating neutron star, which emits pulses of radiation from gamma rays to radio waves with a spin rate of 30.2 times per second. The nebula was the first astronomical object identified with a historical supernova explosion.

The nebula acts as a source of radiation for studying celestial bodies that occult it. In the 1950s and 1960s, the Sun's corona was mapped from observations of the Crab's radio waves passing through it, and more recently, the thickness of the atmosphere of Saturn's moon Titan was measured as it blocked out X-rays from the nebula.

Messier 3

Messier 3

Messier 3 (also known as M3 or NGC 5272) is a globular cluster in the constellation Canes Venatici. It was discovered by Charles Messier in 1764, and resolved into stars by William Herschel around 1784. This cluster is one of the largest and brightest, and is made up of around 500,000 stars. It is located at a distance of about 33,900 light-years away from Earth. M3 has an apparent magnitude of 6.2, making it visible to the naked eye under dark conditions. From a moderate-sized telescope, the cluster is fully defined.

Messier 67 Cluster In Cancer

Messier 67 Cluster In Cancer

Messier 67 (also known as M67 or NGC 2682) is an open cluster, or galactic cluster, in the constellation Cancer. M67's Trumpler class is variously given as II 2 r, II 2 m, or II 3 r. It was discovered by Johann Gottfried Koehler in 1779. Its age is estimated at between 3.2 and 5 billion years. The most recently estimated age of four billion years appears to be the most reliable[citation needed]; thus the stars of M67 are most likely slightly younger than the Sun.

M67 is not the oldest known open cluster, but there are very few in the galaxy known to be older. M67 is an important laboratory for studying stellar evolution, since all its stars are at the same distance and age, except for approximately 30 anomalous blue stragglers[1], whose origins are not fully understood.

M67 is one of the most-studied open clusters, yet estimates of its physical parameters such as age, mass, and number of stars of a given type, vary substantially. Richer et al. [2] estimate its age to be 4 Gyr, its mass to be 1080 solar masses, and the number of white dwarfs to be 150. Hurley et al. [3] estimate its current mass to be 1400 solar masses and its initial mass to be approximately 10 times as great.

M67 has more than 100 stars similar to the Sun, and many red giants. The total star count has been estimated at over 500[citation needed]. The cluster contains no main sequence stars bluer than spectral type F, other than perhaps some of the blue stragglers, since the brighter stars of that age have already left the main sequence. In fact, when the stars of the cluster are plotted on the Hertzsprung-Russell diagram, there is a distinct "turn-off" representing the stars which are just about to leave the main sequence and become red giants. As the cluster ages, the turn-off will move down the main sequence.

It appears that M67 does not contain an unbiased sample of stars. One cause of this is mass segregation, the process by which lighter stars (actually, systems) gain speed at the expense of more massive stars during close encounters, which causes the lighter stars to be at a greater average distance from the center of the cluster or to escape altogether[4

All-Star Polar Alignment

All-Star Polar Alignment

All-Star Polar Alignment Technology

German Equatorial Mounts (GEM) have long since been recognized as the mount of choice for astrophotography. Needing to track in only one axis for long exposures; adjustable counterweights and tube position for perfect balance, the GEM has few short comings when it comes to imaging. However accurate tracking still depends on an accurate polar alignment. Even with a visible star very near the North Celestial Pole (NCP), the true celestial pole can be a very elusive place to find without assistance.

Now select Celestron mounts can utilize a new innovative Polar alignment procedure called All-Star. All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment.

Here's how it works.

Once your telescope is aligned with two bright star, All-Star allows you to choose any bright star listed in the NexStar hand control to assist in accurately aligning your telescope's mount with the North Celestial Pole. Using the telescope's Sync function, the mount is able to point and center a bright star with a high degree of accuracy. Once centered, the mount will point the telescope to the exact position that the star should be if the mount were precisely polar aligned. By simply adjusting the mounts altitude and azimuth controls to re-center the star in the center of the eyepiece, you are actually moving the mounts polar axis to the exact position of the North Celestial Pole.

FAQ

Can I use Polaris to polar align my telescope?
Since Polaris is very close to the NCP and not very bright, it is actually not a recommended star for the "All-Star" method. The advantages of being able to use stars other than Polaris are two fold:

  • Polaris is not always visible. So not only can you use a variety of other stars but they are also brighter and more prominent.
  • The star you choose will be farther away from the NCP thus allowing for greater accuracy when centering the star in your eyepiece.

Which stars are best to use for polar aligning?
For best results choose a bright alignment star that is near the Meridian, preferably close to the celestial equator. Try to avoid stars that are close to the west/east horizon or directly overhead because they can be more difficult to center using the mount's altitude and azimuth controls. Also stars too near the celestial pole are less accurate than those further away.

Will I lose my alignment after I polar align?
No, the mount will retain its alignment but some amount of accuracy may be compromised depending on how much the mount has been moved during polar alignment. Although the telscopes tracking may be very good, pointing accuracy may need to be improved, especially if you are trying to located small objects on a ccd chip.

What are the steps to polar align my telescope using "All-Star" polar alignment?

  1. Align the telescope with the sky using the "Two-Star Alignment" method.
  2. Select a suitable bright star from the Hand Control's database and slew the telescope to the star.
  3. Press the Align button and select Polar Align => Align Mount from the list.
  4. The telescope will then re-slew to the alignment star and ask you to center it in the eyepiece in order to "Sync" on the star.
  5. The telescope will slew to the position that the star should be if it were accurately polar aligned.
  6. Use the mounts altitude and azimuth adjustments to place the star in the center of the eyepiece and press the Align button.
  7. Update the telescope's star alignment if necessary.

Motor Control Firmware Updates v.2.2.1

Our latest hand control firmware for computerized goto telescopes, version 4.13, now allows you to update the motor control (telescope mount) firmware through the hand control.  Our hand control firmware is still updated by connecting the RS-232 hand control serial cable (part #93920) directly to the hand control, and then to a computer with an internet connection.

Previously, motor control updates were done through the telescope’s PC Port (CPC and CGE series) using our Programming Cable (part #93922). If your telescope did not have a PC Port (Advanced GT, NexStar SE and NexStar SLT series), you would also have needed our Auxilliary Port Accessory Kit (part #93965)

Our NexStar SE and CPC Series already ship with the RS-232 Cable.  And, if your computer lacks a serial port for the RS-232 Cable, you will also need our USB to RS-232 Converter Cable (# 18775) to connect to your computer’s USB port.

For more information on connecting to a telescope to perform an upgrade, please install and run MCupdate and click on the Help button.
