Smartcamera Approach

The Astrel Instruments cameras are powered by a 1000MHz Processor with 1Gb of memory and up to 32Gb of onboard storage.

Thanks to its "intelligence", the camera can do onboard all the operations that other cameras can only do by means of an external PC, because the camera is a PC itself.

Similar to a powerful astrophotography-oriented DSRL, the camera itself offers an integrated complete suite of easy to use graphical applications including:

  • Photo sequences programming with filters management

  • Temperature setting and monitor

  • Liveview with integrated focus mode

  • Autoguiding with dithering

  • Planetariums with mount control, including plate solving

  • Images review

The camera can autonomously autoguide with many commercial USB autoguider cameras and use planetarium applications to control the mount operations (alignment, goto, ...) on most commercial mounts. Many other commercial devices like motorized focusers, external filter wheels, ... can also be directly connected and managed autonomously by the camera.

The Wireless mode allows using the camera without a PC.


AST8300X Standalone WiFi Integrated PC Tablet
AST8300X Standalone WiFi Integrated PC Smartphone
Astrel SW Tools: Liveview

Liveview: the camera displays a bin 10 image, refreshing up to 3fps. With few seconds exposure even very faint objects become visible, allowing precise framing

Astrel SW Tools: Take Photos

Take Photos: start your photo sequence defining, for each filter, the number of frames, exposure time and binning of the sub-frames. It also sends dithering commands to the guider

Astrel SW Tools: Focus

Focus: enter the focus mode selecting a star in the liveview, which is enlarged up to 8x. The app calculates and displays FWHM and profile with an up to 3fps refresh rate 

Astrel SW Tools: Expsure Monitor

Monitor: follow the current sub-frame number in the sequence and some info about the camera status. It can also preview the last frame or kill the sequence

Astrel SW Tools: Temperature Control

Temperature Control: select a setpoint and the minimum number of seconds/°C and start the PID algorithm that will keep the temperature constant within 0.1°C

Astrel SW Tools: Guider

Guider: connect your autoguider to the camera and use this app, derived from Lin_guider, for guiding your telescope. It features drift graph, statistics and dithering

On camera advanced software

Astrel SW Tools

Thanks to the powerful integrated microprocessor and large memory, any Astrel Instruments camera is by any means a PC, running the Ubuntu OS with hundreds of available applications, including many astrophotography related ones. The cameras come with several pre-installed astronomy applications including:

  • KStars and Cartes du Ciel, two well known planetarium apps that can control most mounts for alignment and GOTO operation

  • Ekos, an image planning and observatory control software using offline for plate solving and INDI standard for equipment control

  • DS9, a powerful app for image review and analysis

Integrated Filter Wheel

AST8300X Integrated Filterwheel

The AST8300-X includes an integrated 7 position filter wheel using 1.25" unmounted filters.

Precision filter positioning: the AST8300-X feature a set of spring loaded balls with corresponding holes for a very precise and repeatable filters positioning: when the correct alignment is reached, the ball enters the hole, elastically recovering any small positioning error.

The AST8300-X-7F consists on a complete kit with the filter wheel fully equipped with Astronomik LRGB + Ha + OIII +SII filter set already mounted.

Cooling and vacuum chamber

AST8300X Vacuum Chamber

The AST8300-X camera features a power consumption of only 2.4A @ 12V in fully operative state with 100% peltier on. In spite of this very low power consumption, an efficient 2 stages peltier cooling system can lower the regulated CCD temperature by up to 35°C below ambient.

The sensor and the cooling chain are contained in a vacuum proof chamber: using the included vacuum pump connected to the valve on the rear of the camera body, in less than a minute the air can be pumped-out. This has 2 fundamental effects: it eliminates the possibility of frost forming inside the chamber and minimizes the convention up and down heat transfer inside the chamber, optimizing the heat removal via the cold finger and avoiding cooling of the optical window that could lead to fogging.

Every camera is tested to maintain a proper vacuum level for at least 3 days (most cameras can hold the vacuum for several weeks). For customers running remote observatories, it is possible to fill the chamber with inert gas like Argon or Kripton, which will stay in the camera for months. The vacuum level can be controlled through the manometer incorporated in the vacuum pump.

No desiccant is needed.

The Wireless mode let the user communicate with the camera through a WiFi connection established between his Tablet / Smartphone (or of course a PC) and the camera. The connection uses remote desktop technology to send the camera display to the connected devices. No wires are needed between the camera and the devices: no risk of stumbling on a wire ruining the work of hours or even damaging your equipment.


As the PC is not needed and the camera only needs a maximum of 2.4A at 12V, in these modes there's no need to carry big battery packs and power inverters: one small battery or even your car's one is enough for a whole night.

All the connected devices use the same integrated software suite: the camera's applications are accessible via remote desktop from any network connected device, including PC, Smartphones and Tablets.

Moreover, thanks to the Open Source license of all the software and the Linux OS, other applications can be easily added by the users, giving the camera more and more capabilities: our aim is to create a community of users and software developers which will add leading edge contents, ranging from innovative readout modes to web enabled applications.

On camera smart software suite

This suite of applications has been developed to make the Astrel Instruments cameras really easy and intuitive to use.

No complicated software: use these apps connecting with your smartphone, tablet, PC and few minutes and clicks are enough to start taking pictures.
