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 an external computer! Our D5600a Cooled, based on
the Nikon D5600, 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 computer.

Based on the Nikon D5600 model, our D5600a 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 computer!
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 D5600a 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
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 D5600a Cooled
uses a cooling system with double Peltier cell thet is able to lower
and keep constant the sensor temperature, up to -27°C with respect to
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 D5600a Cooled
uses a special anti-dewing system that only heats the front filter (and
not the sensor!) allowing you to avoid this annoying problem.
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).

Modified filter for more sensitivity
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.
Cooled camera replaces the original filter with a model designed
specifically for astrophotography increasing the camera sensitivity and
allowing you to take brighter pictures.
Power without battery with dedicated adapter
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 D5600a Cooled
camera presents, at the bottom, close to the 12V power port that power
up the cooling and anti-dewing systems, there's a 9V 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 (3 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 D5600a Cooled camera requires a 12V 3A 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.
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
