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 an equatorial mount with fine motion controls for precision aiming and it has a motor drive for tracking, keeping your target in view. The mount has setting circles for targeting, and is adjustable for height. 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. 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
25mm Meade MA eyepiece (40X)
12.5mm plossl (80X)
6.7mm plossl (150X)
Equatorial mount motorized for tracking
Aluminum tripod with accessory shelf


Celestron Firstscope 114 4.5" Newtonian

Focal ratio: f/8 (910mm focal length)

This is a great small reflector for quick grab-and-go observing. The equatorial mount takes a few minutes to put together, so this would be a good scope to keep set up and just carry outside fully-assembled, but with a little practice a person could easily set up and take down in a remote location as well. The mount is not motorized, but manual tracking is a breeze with the supplied slow-motion knobs. This scope is in good condition and provides excellent images. The tube and mount will easily fit into the trunk or back seat of a car.

Accessories and equipment list:

Equatorial mount
1.25" rack and pinion focuser
5 x 24 optical finder (straight through, reverse image to match scope view)

Coulter Odyssey 8 Dobsonian

Focal ratio: f4.5 (915mm focal length)

This Red 8" classic from the early days of dobs looks near new, and works fine - point and look simplicity. A quality 10X60 finder with helical focuser provides an interesting alternate view of the Moon and large clusters. The 40" tube will fit in any back seat, the rocker box in any trunk.

Coulter Odyssey 8 Dobsonian

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

The 10" Trackball

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 modern, 41 lb folding truss tube dob. Easy to carry, easy to transport, 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.

Accessories and Equipment list:

2" rack and pinion focuser with 1.25" adapter
6 x 30 RACI Finder
32mm plossl (36X)
15mm plossl (77X)

Little 10

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.

Accessories and Equipment list:

1.25" rack and pinion focuser
Meade 2X barlow – giving 92X, 135X w/above EPs
25mm Meade MA eyepiece (44X)

White Cosmos

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).

Accessories and Equipment list:

2" rack and pinion focuser with 1.25" adapter
6 x 30 Finder
32mm 2” Wide field Erfle eyepiece (47x)

Big Orange

"Big White" 12.5" Dodecagon Split-tube Dobsonian

Focal ratio: f/6 (1905mm focal length)

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. Clever construction (built-in handles on all 3 sections) makes this sizable scope easier to deploy/assemble than it appears.

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 carry 48 lbs (heaviest piece) from garage to observing spot (total weight -- approx 105 lbs).

Accessories and Equipment list:

1.25" rack and pinion focuser
8 X 50 straight through Finder
32mm plossl eyepiece (60X)
17mm Orion Explorer eyepiece (112X)
10mm Plossl eyepiece (191X)
