Canon Digital EOS SLR AstroCamera.
The Canon EOS Astro Camera is a consumer Canon Rebel Digital camera, modified for
astrophotography with the following features / accessories:
CMOS imaging sensor IR filter removed for better H-alpha sensitivity
Knife-edge focuser calibrated for the camera.
Timer remote control (Modified TC-80N3)
Optional UV and IR blocking filter
These are brand-new units, especially modified for astrophotography. They are not covered
under Canon's original warranty, but a Hutech warranty covers the modified unit for 12 months.
Two modification options are available:
EOS001 - Standard IR blocker removed
EOS002 - Astronomical UV/IR blocker installed (extended red response for H-alpha)
Both versions allow the astronomically important H-alpha wavelength to reach the EOS
image sensor, but option 2 blocks the longer wavelengths which may be out of focus in
imaging systems with lenses. The filter used for EOS002 is an IDAS filter UV/IR blocking filter
FAQ's answered:
Can I use EOS001 (no filter) with my refractor?
For use with refractors, configuration EOS002 or EOS001 may be used. In the latter case, a
separate IR blocker or IDAS LPS filter should be mounted in the telescope's optical path.
Can I use the modified camera for normal daylight photography?
Although the modified camera body is intended to be used primarily as a dedicated
astrocamera, with configuration EOS002 the camera body can still be used for daylight
photography with Canon lenses (autofocus is fully functional). The modifications affect color
balance so a modified white balance setting must be loaded into the camera to achieve a
natural color balance in the resulting shots.
Why should I get a knife-edge focuser option for my Canon astro-camera?
For night sky photography, the knife-edge focuser has long been acknowledged as the
method of choice to consistently achieve sharpest focus for film photography without
depending on the observer's visual acuity.
For digital cameras, it is possible to take test photos and examine the result immediately for
best focus either manually or with third-party computer software. But this requires having a
computer with your imaging system, complicating setup and adding fragile, power-hungry
equipment to the imaging system as well as adding data transfer delays. This is not a
problem for permanent observatory setups but a negative for portable imaging. In this case the
knife-edge focuser is the recommended accessory for simplicity and to assure consistently
sharp photos.
