Since the objective was
a high resolution picture,
I used the technique called
¨Ocular Projection¨
Ocular Projection provides the highest
magnification, but it requires critical
alignment of the telescope’s axis with
the eyepiece or ocular.
It took some time to choose, connect,
test, and adjust all the pieces:
Four months after the project started,
the system was ready to capture pictures
with the highest expected performance.
The Ocular Projection System was composed of:
- A 80Kg tripod
holding the whole optical system.
- A motorized telescope mount
accurately following the Moon.
- A 10" Schmidt–Cassegrain telescope
collecting the light.
- A good apochromatic eyepiece
projecting the light over the CCD.
- An infrared pass filter
reducing the effects of atmospheric refraction.
- A Peltier-cooled CCD
capturing the images.
- A laptop
reading and storing CCD data.
