  • Weight with dewcap: 7.3kg.
The Newtonian reflector has a LOMO main mirror, a superb quality optics from Russia. The tube, spider, main mirror cell and the focuser are custom designed and made in Hungary. All parts are of high quality and designed especially for astro-photograpy. Specifications:
  • Tube: made of kevlar to be super light-weight though unbreakable and with no flexture and distorsion.
  • Clear aperture: 305mm.
  • Focal length: 1500mm which is f/5.

Fornax LighTrack II

Fornax 50 german equatorial mount

The LighTrack II is a surprisingly handy and precise piece of equipment allowing me to shoot even with larger lenses without any wobble. For a detailed specification please visit the website of the producer. The Fornax 50 is a Hungarian constructed and built high quality mount. Technical specifications:
  • Max. load of telescope 45 kg.
  • Mount weight 21 kg.
  • Both axis diameters are 60 mm.
  • Cone bearings in x layout (no play!).
  • Both worm wheels diameter 217 mm, 432 teeth.
  • 2-phase stepper motors go directly to DEC and through a belt (to minimize vibrations) to the RA axis, w/o any additional gear boxes.
  • Counter weight axis turns with RA, diameter 33.8 mm.
  • Polar alignment scope and eye-piece included.

Ursa Minor stepper motor controller. Technical specifications:
  • Supporting two stepper motors: 2 phase, max. 3A per winding.
  • Resolution: Full step to 64 x microstep (automatic).
  • Smooth running, acceleration, deceleration.
  • Precise positioning (goto).
  • Totally parallel operation: Running two motors, transmit and receive data through the serial interfaces at the same time.
  • Flexible configuration: current limit, resolution, acceleration parameters, deceleration parameters, speed limit values can be configured independently for the motors.
  • Freeware Windows based program for testing and configuration.
  • Three protocols: Ursa Minor native, emulated Synta Skywatcher EQ5 protocol, basic Meade commands (only for autoguiding).
  • Compatible with Synscan hand controller.
  • Supported by Ursa Minor Pro program (native) and with most of the popular astro softwares through the freeware EQMOD Ascom driver.
The LACERTA M-GEN Stand-Alone Guider is a fully functioning autoguider that will guide your telescope without a PC or laptop. This device consists of two parts:
  • An AUTOGUIDER CAMERA (CCD chip size: 752x852 pixels, 3.6 x 2.7 mm, Type-E SONY ICX279AL, pixel size approximately 4.7 micron) with a standard T2 thread for attaching to a guider telescope or an off-axis guider and
  • A CONTROLLER with buttons and display (128x64 pixels). The display shows the live image of the camera. The stars appearing on the screen vary in size. The bigger the star appears the better for guiding. After selecting the guide star the following parameters can be adjusted:
    • Refresh rate and shutter speed (independently adjustable between 0.1 and 4 sec manually or automatically).
    • Correction speed (for both axes independently adjustable to avoid possible resonances).
    • Tolerance (default 0.5 pixels, but its interpolated value can be as small as 0.1 pixels, and up to 127 pixels).
    • Auto-calibration (it can be chosen that the RA/Dec-Axis to be parallel with the rows of pixels on the AG-chip or to be at a certain angle).
    • On release socket (EOS-compatible timer) provides you the number, time and pause time of the exposures, and the waiting period after the camera mirror lockup.
    • Measurement mode (turn off the correction) for the detection of the periodic error.
    • Various statistics (Seeing measurements, inspection of play of the mount, etc.).
