MGEN-3 has landed!

The MGEN-II is history!

After 10 years, the device that has revolutionized the way ambitious amateurs and professionals guide their astro imaging will be retired. The hardware was at its limits, the market and the needs of astrophotographers have evolved and we, as the leading innovator in guiding, were taking this into account:

Watch on Youtube: MGEN-3 One Button Quick Start Guiding

The MGEN-3 is here!

  • The new, much stronger hardware enables the new self-learning AI multistar guiding,
  • the large color display makes operation more pleasant
  • and with the new quick start function ("push one button") guiding starts with just a single push of a button

Nevertheless, of course, if you want, you have full manual control of all parameters ... but who wants that when the AI ​​continuously parameterizes itself in the background?

  • Stand Alone or PC App controlled // stand alone or controlled via PC App
  • Selflearning (AI) adaptive guiding or manual modes // Self-learning adaptive guiding (AI) or manual setting
  • Easy to use: one button push guiding or manual control // Ease of use: just one button and guidet, or manual control
  • Enhanced high sensitivity with real time darkframe correction // Improved sensitivity with real-time dark image deduction
  • Multistar guiding for extra high subpixel precision // Multistar guiding for improved subpixel accuracy
  • Polar alignment using digital Scheiner method // Polar alignment using digital Scheiner method
  • DSLR / CCD Exposure Control // DSLR / CCD exposure control
  • Dithering modes available // various dithering modes available
  • Guidelog displayed and saved // Guidelog display and saving
  • Arbitrary binning modes // Freely selectable binning modes
  • USB powered (5V), typical 240mA / 1.2W // USB powered (5V), only 1.2W!
  • Aux port for additional equipment // AUX port for additional accessories
  • continuous development, new features // ongoing development, new functions

ASCOM Compatibility

With the Ascom program, the Mgen-3 can be used with almost all CCD / CMOS control programs

The trick here is that the is selected as the Ascom recording camera in the control software, and only then is the real recording camera selected in the itself. This means that the stands between the control software and the recording camera and regulates guiding and dithering which is no longer set in the control software. All other control commands, such as exposure, filter change, autofocus, live image, etc., are carried out normally via the control software. The surface of the Mgen-3 is also visible on the PC screen and can also be operated virtually.
