Large - Aperture Aluminum Telescope System
with SlipStream GoTo Drive
These new SpicaEyes Telescopes combine solid All-Aluminum construction
with a new GoTo drive system that integrates a Slip Clutch on both
axes for full-time manual and motorized slew control.
You can find
objects fast by using the included Argo Navis computer. The telescope
will automatically slew, or you can move it by hand. Once you
find your target, the telescope will track it for you, keeping
it centered in the field of view. The integrated SlipStream
clutches allow you to move the scope at any time by hand or with
the motorized slew control, with no levers to disengage.
Shown to the
left and below is a 28" f3.66 SpicaEyes SlipStream Telescope.
The oversized altitude bearings sit on 1"diameter stainless
steel shafts rotating in pillow block ball bearings. Both axes
are driven by Servo motors through a stand-alone computer mounted
to the telescope. The adjustable slip clutches are fully enclosed
and protected in a metal housing. Thumbscrews allow one to adjust
the drag of the clutches as needed.
hand control gives three-speed slew control on both axes. The
fast slew will spin the scope completely around in less than a
minute, useful for going across large stretches of the sky. The
medium slew will nicely center objects in the field of view at
low and medium powers, and the slow slew will do the same at high
power. All three slew speeds can be individually calibrated to
the user's requirements.

mirrors of the highest quality. The 24" and 28"
mirrors are from Kennedy
Optics. The smaller mirrors are from Lightholder
Optics. The short f/ratios of these exquisite optics
make for a low-profile design with no compromise in image

All-Aluminum SlipStream GoTo Telescope custom built for him by
was taken at RTMC in May. Dan Gray from Sidereal Technology was
there to do some initialization procedures on the drive the first
day, after which the Telescope performed flawlessly for two nights,
with excellent pointing accuracy and tracking. On Sunday night
a wind with 30mph gusts came up, but, even with the shroud on,
the scope was quite steady. The slip clutches can be easily tightened
to withstand moderate winds.
outstanding through Steve Kennedy's 28" f3.66 mirror. We
had a great tour of the Spring galaxies and globulars under dark
skies with moderate to good seeing. The performance of Steve K's
stunning large aperture short f/ratio mirrors are quickly breaking
down some myths and taboos surrounding the subject of sub-f4 mirrors.
There was no compromise that we could detect in the images, just
a shorter trip up the ladder (and a shorter ladder to haul around).
With the 26 Nagler and Paracorr, a bright star panned across the
field stayed sharp from one edge to the other. High power views
through a Denkmeier binoviewer of the bright Spring galaxies were
fabulous, with "best ever" heard from more than one
person. Jupiter was contrasty and as detailed as the seeing allowed.
Mirror alignment with a set of tools and a Howie Glatter laser
was easy enough to do, and the stiff telescope structure kept
