Nearby or in thousands of km, take control of your calibration & flat lamps for Alpy, Lhires III and LISA.

spox1Nowadays, it is more and more frequent to remote control our telescopes. It brings some comfort but also a better quality of observation – because the less we touch the instrument, the less we risk to break the tuning. It is particularly true in spectroscopy.

Most of the spectroscopes in Shelyak Instruments product range today have the ability to remotely control the flat and calibration lamps – specially, it is the case for Alpy 600, Lhires III and LISA.

From the remote control ability to the actual control, there is… SPOX!


SPOX is a small box allowing the remote control of the flat and calibration lamps for Alpy, Lhires III and LISA. It can be manually controlled, nearby the telescope (if you are in nomadic configuration for instance) either through your computer, using an USB cable – whether it is under Windows or Linux.

When designing SPOX, we tried to cover the most possible cases of use. Whatever your telescope is at hand, at the backyard or at several thousand kilometers.
spox6Some of you need an easy-to-use syetem, up and running in a few minutes. Others wish to have the complete control to integrate it into a given observatory control system. SPOX can cover all these needs.

SPOX est fourni avec un logiciel (sous Windows) qui s’installe en quelques clics. Il est également accompagné d’un driver ASCOM, d’un driver Indi (pour un fonctionnement sous Linux). Et si cela ne suffit pas, le protocole de communication est entièrement décrit, avec un exemple d’application en Python.

SPOX is supplied with a software (under Windows) which is installed in a few clicks. It also includes an ASCOM driver, and an Indi driver (for Linux users). And if it is not enough, the communication protocol is completely defined, with an example of application in Python.
SPOX embeds a defective lamp detector – it is specially useful in remote mode. The principle is simple: a red LED switches on if the current throught the lamps is lower than a given (and adjustable) threshold. Note: the detection works only for Alpy and Lhires III.
SPOX is unique, but it can be delivered with various cables set according to your configuration. If you install SPOX directly onto the telescope, we recommend a short cable (0,8m long). It is probably your case if you work remotely. On the other hand, if SPOX is used locally – for example on the table next to the telescope – then rather prefer the cable of 5m..

Besides, if you work with Alpy or one LISA, you will need the complementary cable, which matches the connectors of these instruments.

You can select your prefered cable set when ordering SPOX (see Spox-Modul)

Last but not least: SPOX was developed in “Open source” mode, with a strong contribution of some key actors of the community (Jean-Paul Godard and Jean-Baptiste Butet first of all). This accessory is based on an Arduino. All the detailed technical elements of SPOX are thus completely available – just ask for them!

ZWO Monochrome Astro Camera ASI461MM Pro cooled, Sensor D=55 mm 100.000.000 Pixel

Excellent image quality
The ASI461MM Pro cooled is equipped with a state-of-the-art monochrome sensor that gives you incredibly detailed images. Thanks to the cooling technology, image noise and thermal noise remain at a minimum, so your images are crisp and contrasty.

More Information

Our products are characterised by quality.

  • Remote telescope in use

    Our project near Munich. 600mm RC tube on a DDM100 mount. As observation platform a dome from Astroshell with 3m diameter. The complete system is designed as a remote telescope.
  • SBIG CCD/CMOS Cameras

    SBIG CCD/CMOS Cameras

    Our most popular camera, the SBIG Aluma AC4040 is a large format Scientific CMOS camera, featuring a 16.8 megapixel sensor with 9 micron pixels. The camera is compatible with the StarChaser SC-4 Guider and optional AO-X Adaptive Optics accessories. The Aluma AC4040 is available in Front Illuminated (FSI) and ultra-sensitive Back-Illuminated (BSI) versions. BSI versions are offered with VIS-NIR and UV-VIS optical coating options.
  • Shelyak Spectrometer

    The UVEX is the most versatile instrument in the range. Achromatic by design, it can explore far into the ultraviolet and infrared – at the very limits of what today’s cameras can achieve. The interchangeable gratings (in option) allow different resolutions. Combined with its motorization module, it can be operated remotely. The motorization integrates the control of the calibration module (equivalent to the SPOX module). So it’s easy to do your dark, flats and calibration images remotely. The motorized UVEX is the ultimate version of the UVEX, allowing remote operation. You can remotely control the central wavelength (grating angle) and adjust the spectroscope’s focus.
  • Astroshell Domes

    The Clamshell dome is the preferred observatory dome for LASER COMMUNICATION and BIG-APERTURE telescopes. It is not necessary to synchronize the telescope with the dome. Both "shutters" can be moved and positioned independently to allow wind shading of the optical group. All of our domes are equipped with rugged belt drive systems powered by high performance DC or AC motors and feature industrial grade gears. If you need fast dome opening, we offer a special fast opening shutter drive system. Built up individually or in combined with the SRQ-200 DIMM station, our clamshell dome is the way to go for successful astronomy! CLAMSHELL DOMES provide an unparalleled 360/180 degree field of view for an absolutely breathtaking nighttime experience. When this observatory dome opens, you are truly among the stars!
  • ASA Direct Drive Technology

    New design based on 15 years of experience with Direct Drive mounts. Ready for the most demanding applications in pointing and tracking accuracy, like laser comunication, satellite tracking and general astronomical research.
