EAS Telescope Lending Library
Though most Eugene Astronomical Society members own
a telescope, viewing through different scopes is interesting, eye
opening, and fun. As members of the Eugene Astronomical Society, these are your scopes to check out,
enjoy, and share the views with family & friends. Scopes can be
checked out for a three-month period, renewable for up to a year.
Contact our telescope lending coordinator, Tony Dandurand (by e-mail or at 726-8147) or contact our secretary, Jerry Oltion (by e-mail or at 343-4758) for details.
Meade model 375
90mm (3.5") Refractor
Focal ratio: f/11 (1000mm focal length)
This nice lightweight refractor is perfect to leave set up and ready to take
outside on a moment's notice. Its achromatic objective lens gives nice clean
views with only a touch of color on the brightest of objects. It has a smooth
alt-azimuth mount for easy aiming and easy following of objects. The scope's
1000mm focal length gives a pleasingly wide field at low power yet can zoom in
on the Moon and planets or split tight double stars at high power. The
right-angle diagonal lets you look down comfortably into the eyepiece rather
than strain to sight along the tube. The prism diagonal provides an upright
image for terrestrial viewing. This scope is easily portable in a trunk or back
seat.
Accessories and Equipment list:
1.25" rack and pinion focuser
6 x 30 optical finder
Right-angle star diagonal
Upright prism diagonal
32mm plossl (31X)
25mm Meade MA eyepiece (40X)

Celestron Firstscope 4.5" Dobsonian
Focal ratio: f/8 (910mm focal length)
This is a great small reflector for quick grab-and-go observing. If you hold the door for them, a child could take this outside in one trip (base and tube each weigh less than 10 lbs) and set it up in a minute or two.
A red dot finder and smooth and steady motions make it easy to point to your target. Its 4.5" mirror gathers plenty of light for fine views of the moon, planets, star clusters and more. Easy to transport, this little dob will fit in most any car.
Accessories and equipment list:
Equatorial mount
1.25" rack and pinion focuser
Orion 'Easy Finder II' red dot finder
32mm plossl (28X)
18mm Criterion ASP eyepiece (51X)

8" Orange Celestron Schmidt-Cassegrain
The classic orange Celestron is the scope that started the Schmidt-Cassegrain revolution, with good optics and decent aperture in a small package is easy to set up and easy to use. A long focal length allows easy high magnification for great views of planets, tight double stars, and detail within nebulae and clusters. An equatorial wedge and motor drive give precise tracking, holding objects in the field of view for observing. The drive system runs on 12 volts or 110, so you can plug it into an extension cord if you're near home, or a car battery if you're out in the field. Precise controls for both right ascension and declination allow for guided astrophotography.
Fits easily into any car for transport. Light enough to leave set up and carry out into the back yard for quick peeks. If you've ever wanted to try a Schmidt-Cassegrain, this is an excellent opportunity.
Accessories and equipment list:
Smooth internal focuser
8 x 50 optical finder (w/focuser)
32mm plossl eyepiece (63X)

The 10" Trackball
Focal ratio: f/4.7 (1200mm focal length)
This is a new design developed by the EAS's own Jerry Oltion. It puts standard Newtonian optics in a ball-shaped mount, which rests in a cradle that allows free motion in any direction. You can even rotate the scope to provide a convenient eyepiece angle for any target. The mount has a motorized axle that provides tracking. Just point the scope at your target, let go, and it's tracking. This is the ultimate in grab-and-go scopes: setup takes about 30 seconds. The scope fits easily in the back seat of a car and the mount fits in the trunk or passenger seat. The motor runs on 6 AA batteries (provided) or an external 12v battery.
The optics on this scope are excellent. You can see the E and F stars in the trapezium with it, and split the double-double in Lyra with ease.If you've never used a ball scope before, prepare to be amazed. They're light-years beyond dobs and equatorial mounts in comfort and ease of use. If you bring a stool or chair, you can observe sitting down.
Accessories and equipment list:
Motorized mount for tracking
"Quick mount" for holding scope when off main mount
1.25" rack and pinion focuser
Innovative glow-in-the-dark finder
25mm GSO Super plossl eyepiece (48x)

The "Little 10" -- 10" Folding Truss Dobsonian
Focal ratio: f/4.5 (1150mm focal length)
In 2008, this scope was transformed from a 75 lb light bucket to this

this short 10" can really go low-power for bright, wide field views.
Finding targets is easy with Quickfinder bulls eye sight and upright 6 x
30 finder. Will fit in any car, easy to take camping, or to that dark
sky site. The pictured box stores the secondary cage, eyepieces, and
finders; can also be used as platform to raise telescope-viewing height.

10"
Cosmos Dobsonian
Focal ratio: f/4.5 (1150mm focal length)
A fine, veteran scope, the White Ten has been around. It's shown kids
the moon & planets at star parties, and for one club member every
Messier object (82 in one marathon back in 2002). Recent upgrades
include handles on telescope tube and base for ease of carrying, and new
coating on primary mirror. This scope features a curved spider (no
diffraction spikes) and an open tube for quick cooling. The 15" x 15" x
37" base will fit in most trunks; the 45" tube in most back seats. Total
weight ~ 55 lbs.

Big
Orange 10" Dobsonian
Focal ratio: f/6 (1500mm focal length)
Originally built in early '80s by Club members, this scope was
refurbished in late 2008 with a new solid base, secondary mirror, and
other upgrades. Optically excellent, Big Orange is great for high power
views of the moon, planets and double stars. With 10" of aperture, it
also gives good views of deep sky nebulae, galaxies, and clusters.
A sizable telescope (68" long, ~72 lbs), it requires a small pick-up,
van, or station wagon (it just fits in a Subaru Outback) to transport.
Wheels allow easy movement on smooth ground (garage to driveway).

"Big Blue" 12.5"
Dodecagon Split-tube Dobsonian
Focal ratio: f/6 (1910mm focal length)
Another club member built scope, this 12-sided (dodecagon) split tube is a marvel of woodworking -- and houses a powerful telescope. 12.5" of aperture brings the "wow!" to deep sky observing, and fine optics (and stable motions) can deliver serious magnification for lunar, planetary, and double star enjoyment.
Refurbished in late 2011 with wheels, new mirror coatings, and a new paint job, this 20-year veteran is ready to roll though more decades delivering great views of the universe.
A short stepladder is needed for the 78" eyepiece height at zenith. A van (minivan with rear seats out) or pick-up is needed for transport. Backyard use only requires ability to roll from garage to observing spot. A short stepladder is needed for the 78" eyepiece height at zenith.
