how large a focal ratio your telescope and seeing conditions can handle, however.
Experimentation will be needed to see what your telescope is capable of in the
seeing conditions on a given night. If the image appears somewhat dim and fuzzy
on the computer screen, you may want to consider removing the Barlow lens.

Filters
For some types of planetary imaging, you may want to use color filters to bring
out subtle details. Any standard Orion 1.25" filter will thread into the front of the
SSUEII’s barrel. Try using different color filters on a planet to see which filters help
best show planetary details.
Neutral-density Moon filters and variable-polarizer filters are useful to reduce the
glare from the moon. They can also be used to reduce the glare from Venus.
Solar Filters
Warning: Always use a full aperture solar filter when viewing the sun.
With a properly fitting full-aperture solar filter attached to your telescope, you can
use the SSUEII to take images of the Sun and the sunspots on its surface.
(Filters available through Orion, check the catalog or www.OrionTelescopes.com
for more information).
Flip Mirror
As easy as flipping a switch, the Imaging Flip Mirror enables the astrophotogra-
pher to find, center and focus a target visually with a 1.25 telescope eyepiece,
then photograph it with a CCD camera. All without swapping out any equipment.
It’s a real timer saver, making the normally tedious task of focusing with the CCD
camera alone easier and quicker.

USB Extension Cable
In many instances, it is likely that a longer cable for the SSUEII will be needed in
order to comfortably setup telescope, camera, and computer. We recommend pur-
chasing a 10’ USB extension cable if you need more cord length
(available through Orion, check the catalog or www.OrionTelescopes.com for more
information).
