Shown below is my original typical
setup for astro-photography.
The telescope is a Celestron Celestar Deluxe Computerized 8" SCT,
vintage
1997. I used the Taurus Tracker III off-axis guider and an
Olympus OM-1
camera. The "recycled" blue paint-tub lid in the tripod is
what
I fabricated to use as an eyepiece and accessory holder. I
also made use
of MASSIVE amounts of Velcro. Note the Kendrick anti-dew
system in
use. This keeps dew off of the SCT corrector plate, the
Telrad, and the guiding eyepiece. It's an ugly mess of cables, but it's
indispensable. My observing friends and I joke that "I will NEVER,
EVER be troubled by dew again!" (Except, of course, if I don't
bother to install it or turn it on...) |

Here's a close-up of the Taurus Tracker
III off-axis
guider. This is a wonderful piece of equipment, providing
fail-safe
focusing after a one-time focus calibration to the camera chosen, in
this case
the Olympus OM-1. The eyepiece at 9:00 is the find/focus
eyepiece
(high-power 7mm), and the assembly it's in must (repeat, MUST -- and
don't
forget!) be pulled out to the position shown after focusing if you
don't want to
shoot 45 minutes of black nothingness. The eyepiece at 12:00
is the
guiding eyepiece (12.5mm Celestron Micro-Guide illuminated-reticle
eyepiece)
that is mounted over a small pickoff mirror in Tracker body.
Note the
Kendrick anti-dew strip around the guiding eyepiece. I can
also have one
on the find/focus eyepiece, but normally I just keep the cap on it
since I used
it only occasionally during a photography session. |
