This binocular chair rotates on a ground board like a Dobsonian. The back reclines with the
binoculars attached to the chair back so they maintain the same position relative to your eyes.

Doug Arion
Kenosha, Wisconsin USA
Taking the minimalist approach, this 6" f/7.5 Equatorial
Newtonian has a completely open tube assembly. Unfortunately, Doug says
his observing location in has plenty of light
pollution. Not good for a scope this open, but it is beautiful. This scope
took 4th Place for Craftsmanship at the 1996 Stellafane convention.

Arunah Hill Group
Cummington, Massachusetts USA
Looking almost more like a carnival ride than a telescope, this historical 13" f/12.5
Fitz refractor was restored by the hard work of the entire club.
The tube assembly alone checks in at 300 pounds. The scope took the 2nd Place award
for Mechanical Excellence at the 1996 Stellafane convention.

Scott Berfield
Scott calls this 8" Newtonian "The Zebra" due to it's unique tube consisting of glued strips
of poplar and mahogany. The tube was saturated with epoxy resin and reinforced on the inside
with fiberglass cloth. The mounting is a Super Polaris, and the primary came
from a Meade scope. The mirror cell is held in place with slotted brass plates that
allow the mirror to be shifted between visual and CCD positions.

Tom Bernie
Gloucester, Massachusetts USA
This binocular mount is made from black anodized aluminum tubing. The quality of finish and
smooth movement are comparable to the expensive commercial mounts.
|

Bruce Blanchard
Hadley, Massachusetts USA
The scope here is a commercial refractor, but Bruce made the very nicely machined mounting. The
azimuth moves on a fairly conventional bearing but the altitude discs ride on
Teflon pads
as can be seen in the second photo.

Tony Bolivar
Vancouver, British Columbia Canada
This 12.5 inch f/4.25 Newtonian has scope tube and tripod of aluminum and the equatorial
head is machined carbon steel. The homemade optics consist of a 12.5" diameter full
thickness primary and a 2.6" diagonal.

Steve Bygren
Colorado Springs, Colorado USA
8" Classical Cassegrain
transportable on commercial airlines. The spider and upper ring were
salvaged from a Parks scope and the truss tubes are carbon graphite arrow
shafts. The mounting is a Dobsonian, but fits upon a standard photo
tripod.

Joe Castoro
Long Island, New York USA
This scope took 2nd Place in Mechanical Excellence and 2nd Place in Craftsmanship at the 1995
Stellafane convention. The entire thing is finished in fake granite paint. Note the motorized
jacks, these lift the mount allowing the wheels to be rotated into place.

Bob Crelin
Branford, Connecticut USA
This is a Comet Orrery - the first one ever as far as we know. Moving the knob (the comet's
nucleus) changes the length and angle of the tails with respect to the sun and even shows
the dust tail diverging from the gas tail. The beautiful baroque decorations were drawn with
a simple ball-point pen. This entry took 2nd Place in the Special category at the 1997
Stellafane convention. We think it's one of the coolest and most unique things we've ever seen
at Stellafane. Bob has asked us to add that the whole concept is © 1997, Bob Crelin.

Dan Davidson
Reading, Pennsylvania USA
This 6" f/9 Dob-Newt has dark walnut stained wood and a smooth fiberglass coated sonotube.
Dan is an auto painter which gives him access to the tools to make this really nice tube.
It has a white pearlescent finish that Dan says is a standard Audi color. This scope took
3rd Place for Craftsmanship and 3rd Place for Design at the 1997 Stellafane convention. The
attention to detail on areas like the end rings, the focuser mount, and the spider mounts made
this one of the best scopes on Breezy Hill. As you can see in the third photo, it's also
fully baffled.
|

|
Scott Degenhardt
This 12.5 inch f/10 Newtonian features a Crayford focuser built from
these plans here on AstronomyDaily.com.
The scope also has remote 2-axis collimation, full baffles, and a primary mirror from
Nova Optical.

 |
|
Paul Dellechiaie
The eyepiece maintains an almost constant position on this TeleVue Genesis. The mount is a
unique sort of hybrid Springfield-Dobsonian called a "Torqued-Arm Mount." They are
usually used on a Newtonian, with the counterweight bar pointing upwards.

John Desbiens
Hillsboro, New Hampshire USA
This 12.5" f/6.4 Dob-Newt took 1st Place for Craftsmanship at the 1996 Stellafane
convention. It features a primary mirror by Steve Eldrige, who took the 1st Place award
for Optical Excellence with another scope.

Roy Diffrient
Monkton, Maryland USA
This Dobsonian was not only featured in Sky & Telescope (Feb, 94), but won 1st
Place in Craftsmanship and 3rd Place in Mechanical Excellence at the 1995 Stellafane
convention. By the way, the letters under the mirror cell stand for Fan, Heat, Lights,
and Circles (setting circles, that is).

Steve Durham
Long Lake, New York USA
It seems the power company said that the cherry tree in Steve's front lawn had to come down.
Steve harvested the wood and used it to build the tube, equatorial mount, and tripod for
this scope. He reports there are two larger trees that may come down in the near future!

Louis Fowler
Louisville, Kentucky USA
Designed from Richard Berry's Build Your Own Telescope and a sales brochure
on the PortaBall commercial telescope. His first scope, it is an 8" f/6, with the
spherical base made
from an acrylic light globe reinforced with fiberglass. The base is a bar
stool cut at angles to hold the sphere. He reports his wife is still
looking for the stool. The upper cage is made from PVC pipe with the
excess weight cut off.

Fritz Garrison
Jericho, Vermont USA
This 4-1/4" f/6 Newtonian is made from clear Plexiglas mostly as a teaching tool. The layout of
all components is clear (no pun intended) and by filling it with smoke, the actual light
path can be seen. But clear out the smoke and it's a completely functional scope. Fritz earned
the Innovative Component award at the 1997 Stellafane convention with this scope.
Fritz's daughter, Emma Garrison, took the 2nd Place award in the Junior category
with this scope.

This meteor speed determination device works by cutting off the lens at a predetermined
rate during long exposures, resulting in dashed meteor trails. The spacing of the dashes is
then used to measure the meteor's speed.

Erwin Herrig
Chemnitz, Germany
This 10" Yolo reflector was fully described on Erwin Herrig's web page,
but it's no longer around. David Stevick has the English abstract, and lots of
other information on Yolos, Schiefspieglers, and of course, Stevick-Pauls on his
web
site. Look around while you're there, it's a great site.

Michael Hill
Marlboro, Massachusetts USA
This is a "solar observatory in-a-box", which is a combination Spectroscope, Spectrohelioscope,
and Prominence scope. A full construction article for this design is available
right here on AstronomyDaily.com.
This more conventional scope was shown at the 1997 Stellafane convention. Although it is not
as specialized as the solar observatory, this 8" f/8 Newtonian did have a solar filter
attached when we looked at it.

Cap Hossfield
New Milford, New York USA
Cap built this solar projection theater to view the 1998 total eclipse in Aruba. Built from
balsa wood and heat shrink plastic film used to cover model aircraft, it is
collapsible and
weighs less than a 35mm camera.
This sundial is made entirely from balsa wood. Despite it's solid appearance, it weighs less
than a pound. It took the 3rd Place award in the Special category at the 1997
Stellafane convention.

Steve Hubbard
This 8" f/4.45 Newtonian follows the true John Dobson tradition - it's made of readily available
parts for almost no money! The "tube" is made from angle aluminum with aluminized bubble
wrap attached with Velcro. The altitude bearings are PVC pipe and the tripod is made from crutches.

David Iacovone
South Plainfield, New Jersey USA
David reports "This started out as a simple refractor!" Later he went to a larger objective
and the original optical tube became the new scope's drawtube. Well, this type of re-working
continued unabated for quite a while, so now the "Adapt-a-Scope" has all the
interchangeable objectives, focusers, drawtubes, adaptors, camera mounts, etc.
pictured here, including a 13-7/8" objective lens with a 36" focal length. In the
latter configuration, the four-element design includes the plano-convex primary, a positive
meniscus corrector, and a doublet color corrector lens. They all switch in and out and
lock in place with thumbscrews.

Kelly Jons
Willoughby, Ohio USA
The prototype for this folded refractor was fully described in the February 1997 issue of
Sky & Telescope. The scope he brought to the 1997 Stellafane convention is a 4" f/10
mounted in a 6" diameter tube. Kelly received the 4th Place Craftsmanship award and the
4th Place Design award for this scope.

Carl Lancaster
This 10" f/6 Newtonian on a split-ring mounting features a gigantic declination drive gear. It
was made from a long rack gear that was bent around and screwed to the semi-circular spoked
wheel on the declination axis.

 |
|
Joe Lemay
This 6" f/10 refractor rides on a super-smooth Dobsonian style mount. The upper end of
the pier ends in a "ground board" with three Teflon pads. The forward portion of the
mount has a chamber for holding counterweights.

Pierre Lemay
Blainville, Quebec Canada
Despite it's appearance, this scope is not made from a bowling ball!
The ball is cast from fiberglass and features a single aluminum truss tube
and a nylon block for the focuser. It is
polar aligned and rests on a Poncet-style driven roller.
|
 |
|
Bill Lennartz
Despite it's professional appearance, this 16" f/4.5 Newtonian is made mostly out of parts
from the local hardware store, except for the optics from Galaxy. The driven equatorial fork
mount is made of wood so vibrations dampen quickly. The drive system consists
of a 1 rpm synchro motor driven threaded rod, with a traveling nut that pulls a
cable around a disk. The disk is clutched to the polar axis. The RA shaft is 4"
diameter, 1/4" wall aluminum tubing and the declination bearings are UHMW
polyurethane riding on Formica, all screwed or epoxied to plywood. Construction
time was about 1-1/2 years.

 |
|
Rob Miller
His first home-built scope, this is
a 10" f/4.5 with optics from Orion Telescope Center. The
tube is made from birch plywood with the octagon made up from four 4"
slats and four 5-5/8" slats interleaved. The mirror cell includes the
valve springs from a motorcycle engine! A bit of elbow grease and paint
made a beautiful mount from a pile of rusting metal.

Bob Novack
Cranberry, Pennsylvania USA
The first scope is an 6" f/10 Stevick-Paul that took the 2nd Place award for Design at the
1997 Stellafane convention. More details on this design can be found on David Stevick's Home Page.
The other scope here is an 8" f/5 Newtonian on a Dobsonian mount.

Dennis O'Connell
Corning, New York USA
Dennis is definitely the "King of PVC Scopes". Among his collection are a folded refractor and a
Dobson-style solar telescope. The latter is not a reference to the mounting, John Dobson also
invented this unique solar telescope concept where the filter and diagonal are the same
piece of glass. If the filter ever breaks or falls out of place, there's no risk
of viewing the unfiltered sun, because your diagonal is gone now as well. There
is an extensive article on this style in the August 1989 issue of Sky and Telescope.

Rob O'Toole
Chester, New Hampshire USA
This 10" f/6 Dobsonian was built in about 10 months. It uses 1/2" plywood throughout and
has a primary mirror from Parks Optical. One of the more interesting features is the
Quaker oatmeal box used as a protective enclosure around the secondary mirror.
Four slits are cut in the end of the box to engage the spider vanes. A plastic
lid is snapped over the end and you have a dustproof cover for the secondary.
Rob's four year-old son is the photo model.

Phil Owen
Although it appears to be a basic pipe-mounting, This 8" f/6 Newtonian glides on
Teflon bearings concealed in the machined pipe fittings. This is Phil's first
scope and he reports total cost was under $250.

Pat Passalacqua
Rome, New York USA
This 6" f/9 Newtonian features beautiful woodwork all over and unique bronze shafts. It
was awarded 1st Place in Craftsmanship at the 1997 Stellafane convention. The tube is made
from a cardboard sonotube with a multi-layered wood veneer. The usual problem with using veneer
on a telescope is that dew can seep into the thin wood layer and soften the glue over time. The
veneer that Pat used here includes a foil layer that keeps the assembly waterproof.

Jim Paulsen
Underhill, Vermont USA
Jim showed two scopes at the 1997 Stellafane convention: a 4-1/4" f/10 Newtonian on
a pipe mounting, and a 10" f/6 Newtonian without any real mounting at all. The
scope rests on a tray at the mirror end and is supported by prop arrangement at
the truss tubes. Jim just lifts and moves the prop end for rough re-positioning
and uses a screw driven slow motion control on the prop for fine aiming.

Dave Prowten
Concord, Massachusetts USA
This 10" f/5 Newtonian is built with a polar axis made from the front fork of a Norton
motorcycle. We hesitated to ask Dave how long it took to drill all those lightening
holes in the mirror cell!

 |

|
Fred Quarnstrom
This 10" Dobsonian (based on the design in "Build your own Telescope, by Richard Berry), sits
on a cylindrical bearing equatorial mount made from plans available right here on AstronomyDaily.com. The tube is made of fir
strips ripped from 2x4's and coated with fiberglass. A wooden platform and shock
cord holds a video camera for making solar or lunar videos. This scope took the
Best First Scope award at the 1995 Table Mountain Star Party.

Ron Ravneberg
Columbus, Ohio USA
All feature a unique dual truss tube design
and a head assembly consisting of a simple board. The head-board slides
into a slot in the mirror box for storage and on some of the scopes can be
slid higher or lower to provide different focal plane locations. A circle
of thin black plastic Velcro's to the diagonal to block stray light. Ron
has also contributed very complete construction
notes for this design.

Bruce Rubin
Newburgh, New York USA
This 15" f/4.5 Dobsonian (blue) weighs just 80 lbs. The mounting, mirror
box, and head assembly are all made from sheet aluminum. The truss tube
assembly attaches in a manner that allows it to fold up as a single piece.
This scope (red), from the 1997 Stellafane convention, is a 18" f/4.5 and features
telescoping truss tubes and the same unique one-piece folding truss tube assembly. The
break-down procedure is fully depicted in the photo series at left. Yes, that small box in the
final picture is the entire 18" scope! The last photo shows the 18-point flotation cell.
The wire running between the pads keeps them all properly aligned when the mirror is removed.

Steve Swayze
Portland, Oregon USA
These are among the many scopes built by Steve Swayze and his brother Bruce. The
first is a 40 inch (!) which is 17 feet high when pointed at the zenith. To get
a sense of scale, the "finder" scope mounted on it is a 12.5". That's Oregon's
Mt. Hood in the background. The next photo is a 12.5" f/5, done in dark red
padauk and maple. Finally, the truss-tube scope is a 12.5" f/6.6 done in nara
and birds-eye maple. These and more scopes can be found at the Swayze Optical web site.

|
Bruce Szablak
This 10" f/6 Dob-Newt has a tube that comes apart in the middle so it will fit in
his Honda Accord. To keep weight down the tube is made from 1/4" plywood. Fitting the
panels into routed grooves in the 1 x 2 corner pieces and using internal baffles help keep
the tube strong and rigid. Trunk latches are used to secure the two sections together
and a baffle made out of 3/4" plywood extends out of the lower section to provide for a snug fit.

Bill Tomaszewski
This 6" f/8 planetary Newtonian is just loaded with great features: 1) It has a unique focuser that
lets the eyepiece actually drop below the level of the tube; 2) the finder bracket
incorporates a solar finder; 3) the primary is offset towards the focuser side of the tube to allow
an even smaller diagonal; and 4) the spider employs a single vane held under tension with two
sets of wires. Bill's scope received a special Innovative Component Award and 3rd Place for Optical
Excellence (under 12.5") at the 1996 Stellafane convention.
|

|
Jim Vail
This unique camera tracking platform received a Special Award at the 1995 Stellafane
convention. It works like a two-part barn-door tracker, but in a different plane,
sort-of. You can figure out how it works by carefully studying the photo.

Mike Ward
Saratoga, New York USA
This Dobsonian took 3rd Place in Craftsmanship at the 1995 Stellafane convention. An
especially nice touch is the upper cage assembly, lined with one of the far southern
charts from Sky Atlas 2000.0, it is very Questar-esque.

Allon Wildgust
Brandon, Vermont USA
This outstanding 8" f/5.4 Newtonian on a Jamieson mount took three awards at the 1996 Stellafane
convention: 1st Place for Mechanical Excellence, 2nd Place for Craftsmanship, and 2nd Place for
Optical Excellence (under 12.5"). First described in the May 1994 Sky & Telescope
this mounting is cross between a Dobsonian and an equatorial. Kinematically it's a German equatorial,
but it uses classical Dobsonian components and construction techniques. This example is probably
one of the finest scopes ever shown at Stellafane.
|
 |
|
Peter Wraight
This Dob-Newt Binocular is one of the best binocular scopes we've ever
seen. The over-and-under design fits nicely in a normal Dobsonian style mount.
The lower scope has a larger diagonal and it's light goes up through the upper
scope to the side-by-side eyepieces. This scope took 1st Place for Mechanical
Excellence at the 1995 Stellafane convention.
