iOptron GEM28 1.5″ Montering iPolar Tripod: Duitse GoTo-montering met elektronische poolzoeker
The iOptron GEM28 is a classic German equatorial GoTo mount with a payload capacity of 28 lbs (12.7 kg), excluding counterweights, at a weight of only 10 lbs (4.5 kg). Its latitude range of 10 to 70 degrees makes it suitable for all of Europe.
In this version, the iPolar electronic polar scope is built into the polar axis. Alignment is done on your laptop screen: fast, precise, and even without a clear view of Polaris.
The 1.5-inch stainless steel tripod completes the setup.
GoTo with 212,000 objects
The Go2Nova 8409 hand controller contains a database of over 212,000 objects. After alignment, the mount automatically slews to planets, nebulae, star clusters, and galaxies, keeping them precisely in view.
Via the built-in WiFi, you can also control the mount with iOptron Commander or planetarium software; ASCOM support enables full computer control. An ST-4 port is ready for autoguiding.
Smooth and precise mechanics
Stepper motors with belt drive move both axes smoothly and evenly. The periodic error remains below plus or minus 10 arcseconds and can be further reduced with recordable PPEC.
The gear couplings lock with a positive click and can also be operated with gloves. The Vixen saddle accepts dovetail rails as standard.
Align on screen
Connect the iPolar to your laptop via USB; the free software displays the celestial pole and the direction of the polar axis and calculates using date, time, and atmospheric refraction.
Within minutes, the mount is exact, ready for long exposures.
