Product description:

The 12" astrograph on an EQ-8 mount is a heavy observatory instrument and phenomenal for astrophotography. Its f/4 aperture ratio and 1200mm focal length allow you to capture detailed images needing only a short exposure time.

Omegon f/4 astrograph - for unforgettable astronomy photos
Which other type of telescope can be used to create a beautiful image with so little effort? With Omegon astrographs this is easier than with 'ordinary' telescopes. Why? The answer is obvious - because an aperture ratio of f/4 means a big light output and consequently shorter exposure times. Immerse yourself in the world of deep sky photography. Admire faint galaxies or details in hydrogen nebulae. The Omegon astrograph sets a new benchmark for your astronomy photos.

The advantages in a nutshell

  • f/4 astrograph - a telescope with ultra-fast aperture ratio for short exposures
  • suitable to go on medium mountings due to its short overall length
  • wide field of view for extended objects - approx. 24mm is illuminated
  • 94% reflection parabolic main mirror for bright images
  • large secondary mirror - good illumination for DSLR cameras
  • robust 2" Crayford focuser with 1:10 reduction and 1.25" reducer
  • faster cool-down for getting started observing quicker - main mirror fan

94% reflection f/4 main mirror
Astrographs are suitable for visual observing, but only show their full potential when used for astrophotography. Their f/4 aperture means they are among the 'fastest' Newtonian telescopes around, allowing you to take shorter exposure images.
The secondary mirror and the parabolic BK7 main mirror are 94% reflective, providing brighter and higher contrast images. One can see a visible improvement when compared to a 'normal' mirror which is around 88% reflective.

No shadows, only light - large secondary mirror
Attach your DSLR camera or a modern CCD camera to the telescope and enjoy impressive illumination over a wide field of view. No shadowing is noticeable thanks to the particularly large secondary mirror (see also below). Observing with 2" wide-field eyepieces is now perfect.

Less mistakes - more fun with the photography
The particularly short OTA length and focal length means the telescope is compact - the astrograph is about 20% shorter as compared to an f/5 system. This means you can also use this OTA's excellent optics on a medium mount, saving yourself the expense and clumsiness of a heavier mount.
Another advantage is that the astrograph is perfect for extended deep sky objects thanks to its shorter focal length. This system is also more tolerant of small tracking errors than a telescope with a longer focal length. You will achieve some astounding astrophotography with even just a little effort.

EXTRA HEAVY-DUTY COMPUTERISED GO-TO EQUATORIAL MOUNT

The Sky-Watcher EQ8 is an exciting new extra heavy-duty, observatory class German equatorial mount, with a payload capacity of up to 50kg. Quiet in operation, the EQ8 is supplied with the Synscan Go-To handset and can automatically find and track over 42,900 celestial objects from its extensive computer database.

Available either complete with pier tripod or as the mount head only, to install onto a static pier. Two 10kg counterweights and the Synscan handset are supplied with both options.

Freedom-Find™ Technology

A great feature of the EQ8 is the patented dual-encoder technology. Auxiliary encoders are located on both the R.A. and DEC. axes. This allows the telescope to be moved manually, by releasing the clutches, or electronically in either axis without the mount losing its alignment or positional information. After moving to a new object, the mount will continue to track it accurately. This gives the user enormous freedom, convenience and flexibility during observational sessions.

Permanent Periodic Error Correction (PPEC)

The EQ8 is equipped with an index on its R.A. worm. After a proper PEC training routine, in which the training data is stored in the motor controller permanently, the user can start the PEC training at any time to improve its tracking performance for short focal length astrophotography. A training process is not required in the next observing session, assuming the polar alignment is always accurate, thus this is a permanent periodic error correction (PPEC), and the user can train the mount for manual guiding or auto-guiding.

Auto-Home Function

The EQ8 is equipped with two home position sensors. Working with the Synscan hand controller, the mount can be placed to the same home position after turning on the power.

Batch Exposure Function

The EQ8 is equipped with a SNAP port which can control the shutter release of a camera. Working with the Synscan handset’s ‘Camera Control’ function, a user can take batch exposures when doing astrophotography. Up to 8 groups of ‘exposure times & frame’ combinations can be set on the Synscan handset.

The compact Omegon f/4 astrograph is excellent for using short exposures to produce impressive wide-field astronomy photos.
