Recent news

  • 2017 April: Remaining units tested and installed.
  • 2017 February: First light curves from the Fly's Eye (see in the gallery).
  • 2016 March: Fly's Eye installed at Piszkéstető. First mosaic image obtained (JPG, scaled down to 70%, 4.6M).
  • 2015 July: Weatherproof enclosure built. For pictures of the enclosure and the camera rack see the presentation at the XXIXth IAU GA.
  • 2014 August: Custom plastic parts for camera racks 3D printed, camera rack assembled.
  • 2013 December 13.: A working hexapod model is designed for demonstrational purposes. If you have access to a 3d-printer, you can download the model from Thingiverse and print your own hexapod for your desktop.
  • 2013 November: The prototype of a new USB-drive is ready. This is a fast, small-capacity drive (currently 2MB), that is failsafe, has no moving parts, and is infinitely rewritable (unlike traditional USB drives/SD cards). This will be mainly used to store the system logs.
  • 2013 September 15.: The building of the instrument's future substructure, an iron-reinforced concrete block at Piszkéstető is done.
  • 2013 June 5.: The 3D printer has arrived. This will be used for printing uniquely designed plastic components, e.g. cable sorters.
  • 2013 June 7 – 12.: The first long-term tests with one camera at Piszkéstető. The tracking seems to work now fine even at the level of ~2"/pixel (for these tests, we used an 800mm, f/8 mirror lens, yielding a plate scale comparable to the seeing).
  • 2013 May 22.: The first set of Sloan g/r/i filters has arrived.
  • 2013 May 1.: First light of the Fly's Eye with a single camera looking towards the zenith. The tracking works (see animations with tracking off and tracking on), but needs refining. The animations show a cadence of ~15 sec and 44"/pixel resolution, covering 6×6°.
  • 2013 April 30.: Final assebly of the leg electronics, communication interface and embedded control.
  • 2013 April 23.: First light of the FLI CCD with the target lens.
  • 2013 April 16.: Final assebly of the individual legs as well as the complete hexapod (without the electronics).
  • 2013 April: Control of the Canon objective works.
  • 2013 February: Manufacturing of hexapod leg parts and components has been started.
  • 2013 January: CAD drawings have been finalized.
  • 2013 January: Prototypes of motor driver and position encoder circuit boards passed the performance tests.


The milestones are noted as past, passed successfully, on what we are working now and further ones.
  • 2011 summer: the first design initiatives of the Fly's Eye camera system;
  • 2012 February: a proposal has been submitted to the Hungarian Academy of Sciences (HAS), applying for funds to build a full working instrument;
  • 2012 April –: theoretical and mechanical design of the hexapod platform;
  • 2012 June: the proposal has been accepted by the HAS (LP2012-31, “Lendület” programme);
  • 2012 fall: seeking for grants to build two other Fly's Eye devices;
  • 2013 April: the hexapod platform is ready and working;
  • 2013 May, early June: first light measurements, focusing on proper sidereal tracking and astrometric calibration;
  • 2015 summer: weatherproof enclosure built;
  • 2016 March: first multi-camera observations with 7 units;
  • 2017 February: first light curves;
  • 2017 April: remaining units tested and installed;
  • 2017 summer/autumn: observations with the full camera system, fine tuning of the reduction pipeline
