maestroMultiple Camera Synchronization

Introducing MaxIm DL Maestro, a game-changing new capability for our Cyanogen Imaging® MaxIm DL Pro, the gold standard in astronomical image acquisition and processing software.

Maestro for Imaging Harmony

MaxIm DL Maestro synchronizes multiple simultaneous cameras under leadership of a primary imaging system. You will achieve results more quickly, and can substantially increase the number of images that can be taken per night. Drive your imaging productivity to new highs. 

How it Works

An observer or telescope operator designs an observation plan to take advantage of multiple imaging systems, sharing a common telescope mount. The primary imaging system is the leader, taking images and providing coordination to the subordinate image systems running their own imaging tasks. 

Maestro leads the subordinate players in concert, much as the conductor of an orchestra leads the musicians with their own instruments. Unlike a symphony conductor, it also performs its piece on the primary imaging system.

The lead imaging system runs MaxIm DL Pro with a Maestro server, and operates the standard complement of observatory equipment including camera, filter wheel, guider, mount, dome, etc.  Each additional Maestro client – a limited version of MaxIm DL Pro – operates a single additional camera and filter wheel.

Like a band leader, the Maestro server gives cues to all interested Maestro clients and checks that the slowest client is ready to move to the next part.   


Your Countless Possibilities

One-shot array of mono-band cameras

One camera for each unique band pass filter, such as a Hubble palette narrowband set (SII, Hα, OIII), or  one camera for Luminance, Red, Green, and Blue, on separate telescopes on a common mount.    

Array of identical offset cameras

Cover more sky at the same time for a wider field. Meteors, comets, wide field images or Space Situational Awareness applications may use this capability.  

Array of identical aligned cameras

Cover the same area of sky with more effective total aperture. These can be used in applications for deep discovery —similar to the Dragonfly Telephoto Array.

Array of dissimilar cameras

Trigger multiple cameras with unique capabilities, such as differing field size, quantum efficiency and spectral response. Use a piggybacked DSLR for wide field while using your telescope with your main camera.


Maestro can run multiple-instances of MaxIm DL Pro on the same computer. Do simultaneous B and V photometry with 2 cameras on twin telescopes on a shared mount.

Networked Nano Computers

Maestro can run instances on subordinate computers connected using TCP/IP networking. Use a nano-PC for each camera and instance.

What you need to get started

MaxIm DL Maestro is an upgrade to the next level of MaxIm DL Pro software. You need Maxim DL Pro for your main camera and guide camera, and then add a Maestro Server license to control one additional imaging camera. If you need more than 2 imaging cameras, add Maestro Client licenses for cameras 3 and beyond.

The minimum hardware configuration would require 2 imaging cameras, in addition to the guider on the lead system, and sufficient PC resources to run 2 instances of MaxIm DL Pro, in addition to your other software. When running multiple identical cameras, the driver must support configuring which camera is to be used for each instance.  Maestro does not control multiple mounts.

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.
