iOptron Mount GEM28EC LiteRoc

 

PRODUCT DESCRIPTION

 

 

Like most iOptron GEM models, the new GEM28 is designed for convenience and portability.

The mount can take a payload of up to 12.7 kg and offers an optimally balanced ratio (2:8) of weight to payload.

This ratio enables a fairly high payload with little own weight and thus ideal conditions for mobile astrophotography and observation.

Additional, very useful functions for user comfort and advanced functionality have been implemented by iOptron with the new GEM28.

A built-in WiFi system (easy to use even if you wear gloves) and an integrated WiFi that now permanently records the periodic screw error (PEC protocol).

In terms of functionality, the GEM28 delivers precise approach and extremely accurate tracking of the objects. The GEM28 thus sets further standards for medium-sized equatorial GoTo systems.

The GEM28EC is again equipped with the latest Go2Nova® technology and thus has one of the most powerful and precise GoTo technologies currently available on the market.

The database of 212,000 listed objects ensures you never run out of targets in the sky...

The Go2Nova® hand controller is intuitive to use and its large four-line LCD display makes it extremely easy to set up the mount and find objects.

The GEM28EC is equipped with the electronic "iPolar".

 

The advantages at a glance:

• Latitude range from 10° ~ 70°
• ideal for visual observation and astrophotography
• low periodic error (<± 10 arcseconds)
• Carrying capacity of 12.7 kg with a pure mount weight of 4.5 kg
• CNC-milled die-cast mount head
• large, easy-to-use quick couplers
• Stepper motors with low power consumption
• belt drive
• "easy polar alignment" for those who can't see the pads
• Go2Nova® hand controller with advanced GoTo technology
• integrated ST-4 autoguiding port
• built-in WiFi
• USB port for firmware update and computer control
• Die-cast metal tripod spreader with accessory tray
