CDS COOLED Z6 USER GUIDE
Characteristics of the modification
•
CDS Cooled Z6 is modified versions of Nikon’s general purpose Mirror-less cameras.
Some of original features of Nikon camera were removed and new features such as
TEC cooling and Drop-In filter holder System are added for high quality
astrophotography. Followings are the differences made by the modification.
1.
Low Pass Filter of original CMOS sensor was removed.
2.
In CDS Cooled Z6 Hoya Clear filter installed , and image
blurring can occur due to chromatic aberration on IR lights
recorded on the sensor so the image sharpness can
suffer. This is more pronounced in the images taken with
refraction optics than reflection optics. We recommend
you to install in Drop-In filter holder UV/IR cut filter, light
pollution filter and deep sky filter at the same time while
imaging. Most Astronomical filters cut IR light and will help
to remove IR halo or blurring.
3.
With CDS Cooled Z6, you can take IR images by
mounting a visible light blocking / infrared transmitting
filter such as a Hoya R72 filter.
4.
Various 2” imaging filters or 52mm filters can be mounted in the Drop-In filter holder(DFH48).
