CENTRALDS ASTRO 80D USER GUIDE
Introduction
Astro 80D is a cooled camera that modified 80D of Canon.We took out the image sensor from the
inside of camera body and attached a TEC cooling module on to it and made it to a high
performance Astronomical cooled camera.The image sensor can be cooled maximum -18℃( ±
2℃) below ambient by the installed TEC cooling module.
Informationsofproduct
＊Cool down the temperature of CMOS sensor 18 Celsius degree(±2℃) from that of ambient air.
＊Absolutely high-Quality image in B-shutter use compared with usual unmodified DSLR
＊Realtime Monitoring of the cooling temperature by digital thermometer
＊Drop-in filter system
＊AF Lens Adapter for canon lens (option)
＊Use of high efficiency Thermo electric cooler module
＊Power: 12V, 1.7A DC"
＊Low Pass Filter Removed.
＊Optimal design by 3D CAD modelling
＊Precision manufacturing by CNC machine
＊Perfect tuning of optical axis of CMOS sensor by 3 point alignment
＊Permanent Anti-dew system applied.
＊Hoya MC Clear Filter#Installed
* Internal Silent cooling fan installed
* Live-view Focus function alive.
＊Removed function:Low Pass Filter, Mechanical shutter, Sensor Cleaning
＊Net weight: 1200g

Followingsarethedifferencesmadebythemodification.
1. Low Pass Filter of original CMOS
sensorwasremoved.
2. In Astro 80D Hoya Clear filter
installed , and image blurring can
occur due to chromatic aberration
ontheinfraredlightsrecordedonthe
sensorsothe imagesharpness can
suffer. This is more pronounced in
the images taken with refraction
optics than reflection optics. We
recommendyoutoinstallinDrop-In
filter holder UV/IR cut filter, light
pollution filter and deep sky filter at
thesametimewhileimaging.
3. With Astro 80D, you can take IR
images by mounting a visible light
