EXTRA HEAVY-DUTY COMPUTER CONTROLLED GOTO EQUATORIAL MOUNT
The Sky-Watcher EQ8 is a highly-anticipated new extra heavy-duty, observatory class German mount, with a loading capacity of up to 50kg. Whisper quiet in operation, the EQ8 is supplied with the Synscan Go-To - a handset that can automatically find and track over 42,900 celestial objects from its extensive computer database.
The EQ8 is available, in this instance, complete with pier tripod - or as a head-only option for mounting on a static pier.
Freedom - search ™ technology
A great feature of EQ8 is the patented dual-encoder technology. Auxiliary encoders are installed on both on the R.A. located and December axes. This allows the telescope to be moved manually by loosening the clutches, electronically, or in both axes of the mount without loss of alignment or positioning information on the Synscan controller. After moving to a new object, the mount will continue to track it precisely and accurately. This gives the user tremendous freedom, comfort and flexibility during observing or imaging sessions.
Permanent Periodic Error Correction (PPEC)
The EQ8 has a pre-installed PEC to its R.A. worm assembly. After a proper PEC training routine, in which the training data is permanently stored in the handset, the user can start the PEC at any time and improve their tracking performance for short focal length astrophotography. Repeating the training process is not needed in the next observing session, if the polar alignment does not change, so this is a truly permanent periodic error correction (PPEC) with which the user can improve the tracking of the EQ8 for both manual or automatic control.
The EQ8 is equipped with two positioning sensors on each axis. The Synscan hand controller stores parking data so the mount can return precisely to the same position after turning on the power.
Exposure batch function
The EQ8 has a SNAP- port, which can control the shutter of a camera. Working with the Synscan handset, the "Camera Control" function allows a user to take batch exposures when doing astrophotography with a DSLR. Up to 8 groups of exposure/timeframe combinations can be set up on the Synscan handset.
