The power of a cooled CCD camera combined with the ease of use of a DSLR one, all in a single product that allows you to record stunning images of deep sky (but also of the planets and the Moon!). Perfectly usable even without a control PC! Our 700Da Cooled is the perfect solution for those fan people who want to record great pictures without too many complications!

Cooling system with Peltier cell that dramatically reduces the camera noise during long exposure sessions; front sensor filter modified for astronomy for higher sensitivity especially in the wavelengths of the red and then the very important H-alpha line front filter; anti-dewing system and use without battery (power supplied with cable plugged to the cooling system). The large touchscreen display together with the cooling system control electronics that is directly operated by the touch keys located on the camera, make it easy to use and 100% functional even without using an external control PC.


700Da Cooled camera, APS-C color sensor 22.3 x 14.9mm, modified front filter, double Peltier cell cooling system, down to -30°C in respect to external temperature, internal anti-dewing system, power without battery, integrated shutter control, 3" touchscreen display. 

Based on the Canon EOS 700D model, our 700Da Cooled camera combines the power of the CCD camera with the convenience of DSLR to offer, in a single product, a great instrument to take great pictures of the Universe, even without using an external PC!


Technical comment by Filippo: "There is no doubt that the cooled CCD cameras specially designed for astronomy have higher performances compared to a DSLR, although cooled and improved as our 700Da Cooled. This color camera is perfect for people looking for an instrument with large sensor and with a greater ease of use. Moreover, unlike almost all CCD cameras for astronomy, it allows you to record amazing pictures even without the need for an external PC to control it."

Sensor cooling system with double Peltier cell

Astrophotography of deep-sky objects such as galaxies, nebulae and star clusters requires long exposire times, usually several minutes. When we use a non-cooled camera for this application, you may notice a strong electronic noise that ruins the poses not allowing us to record and clearly see the weaker details. To solve this problem our 700Da Cooled uses a cooling system with double Peltier cell thet is able to lower and keep constant the sensor temperature, up to -30 ° C with respect to ambient temperature!

Positioned rear to the camera to maintain a good weights balance, the cooling system has a display that shows the current temperature of the sensor, the temperature we want to achieve, the relative speed of the cooling fan (which does not introduce vibrations) and the intensity of the anti-dewing system for the front filter. Special touch buttons allow you to adjust all the parameters to set the camera as you prefer. Temperature regulation is absolute then the sensor will work at the same temperature all night letting you record (if you want) the dark frames when you prefer!


Anti-dewing system of the front filter

Sensor cooling requires attention as it can lead to front filter dewing. For this reason our 700Da Cooled uses a special anti-dewing system that only heats the front filter (and not the sensor!) allowing you to avoid this annoying problem.

The anti-dewing system can be controlled and adjusted using the same keys that regulate the cooling system. It's possible to adjust the power of the heating with 5 levels to best suit the humidity conditions (1 = minimal heating; 5 = maximum heating).

For added protection, only when used in high humidity (with humidity at or near 100%), we recommend the use of our Canon EOS T2 ring with filter holder that, with the inclusion of one of our 50.8mm diameter filters, completely seals the internal part of the camera and then provides complete protection against dewing.

APS-C sensor with big dimensions

The main advantage of DSLR cameras with respect to the dedicated CCD cameras for astronomy is to have a large sensor, bigger to the one of CCD cameras of comparable price.

To the right, you can find a comparison of the sensor size of our 700Da Cooled camera (in red) with the Sony and Kodak sensors installed on many CCD cameras for astronomy, such as Atik (in blue). As a reference we also report the size of a Full Frame sensor which also corresponds to the one of the old film cameras.

Notice how the sensor of our 700Da Cooled camera is much larger than the others: the use of the cooling system allows you to have a cooled camera at a lower cost than the one of CCD cameras for astronomy with similar sensors dimensions!


Modified filter for more sensitivity

In order to keep a proper color balance in daylight use, DSLRs use a filter placed in front of the sensor that is not completely transparent, especially at longer wavelengths corresponding to red. In astronomical application that is a problem because the most important emission line, the H-alpha (emitted by many nebulae for example) is right in the red part of the spectrum.

Our 700Da Cooled camera replaces the original filter with a model designed specifically for astrophotography increasing the camera sensitivity and allowing you to take brighter pictures.



The chart on the right compares the transmittance of the modified filter installed on 700Da Cooled (red curve) with the original one of the Canon EOS 700D (blue curve). For reference we reported in green also the position of the H-alpha line .

You can see how from about 550nm original filter decreases transmissivity while our modified filter lets all the light pass up to 700nm, so you can record more easily all the red weak details. The difference is huge considering the H-alpha line where the original filter has a transmissivity of about 30% while the modified one has a transmissivity of about 98%.

Our 700Da Cooled, compared to the original Canon EOS 700D, then it has not only a much lower electronic noise but it's also more sensitive.

Power without battery with dedicated adapter

One of the limitations of the use of DSLR cameras in astrophotography is the battery life. When working at low temperatures the efficiency of the rechargeable batteries drops significantly and it's not unlikely to run out of power in the middle of a pose!

For this reason our 700Da Cooled camera presents, at the bottom, close to the 12V power port that power up the cooling and anti-dewing systems, there's an 7,4V power output. You just connect to this socket the supplied power adapter and insert the other side in the battery compartment of the DSLR. In this way, the single 12V power supply (5 amps) power up both the camera and the cooling system: now you can be sure you can take astrophotographs all night!

Caution: for operation, the 700Da Cooled camera requires a 12V 5A power supply not included in the package.



Integrated shutter control

If you use the camera without a control PC, now you no longer need either manual or timer shutter controller to record your best pictures! In fact we integrate (in the same electronics that control the cooling system) also the shutter control. This way you can set, using the rear buttons, the number of pictures to be recorded and their exposition time.

You can also define the time the camera wait before starting the exposure and the time separating each exposure. You can also set automatic recording of 2 sets of exposures with different exposition times: for example you can set the camera to record 20 images with 300 seconds exposition + 10 images with 900 seconds exposition. Image capture can be stopped at any time by pressing any button of rear electronics.

Number of images you can autonatically record: from 1 to 50
Selectable shutter times for expositions duration: 1, 5, 10, 30, 60, 120, 180, 300, 600 or 900 seconds

Optional shockproof hard shell case for transport:

Who take pictures of the night sky with telescopes often moves in search of no light polluted area. The portability of each instrument is therefore a key parameter. For this reason we offer an optional beautiful shockproof hard case for the 700Da Cooled camera.

Here you can insert and carry your camera and there is also additional space to add other accessories.

The case is IP67 certified for maximum resistance to water and dust, and its structure in polypropylene copolymer can withstand also fall shocks. The inside pre-cut foam cubes let you easily create space for other accessories. Externally it has double-step safety locks and automatic pressurization valve.
