This was my first telescope. It's a two
truss tube design patterned after Ron Ravenburg's "Alice".
This scope is made from half inch cabinet grade birch plywood with walnut
trim. The mirror is a no-name 10" F5.6. I later built a
frame to hold a scope coat for it since light polution in my back yard is
pretty bad. |
 |
My second scope was a four truss-tube design,
housing a Nova 12.5" F5 mirror. The secondary cage is made of
walnut and birch hardwood strips, 3/4" wide and about 1/4"
thick. It's lined on the inside with black Protostar flocking
paper. This is probably one of the best all around scopes that I've
made. |
 |
My first attempt at a refractor. It houses
a noname 5" F8, air spaced achromat doublet. The tube was from
a salvaged aluminum drive shaft which worked very well. The focuser
was my own design of a crayford style. |
 |
My second refractor was made from coopered
walnut and birch strips. The objective is a BW Optic triplet . |
 |
6" F10 with a Mark Harry primary
mirror. It has a 3/4" secondary mirror and a curved spider of
my design. Very nice planetary views. The mirror is about as
close to perfect as you can get. |
 |
New Territory. This is a 6" Maksutov
Newtonian with optics from Intes. These scopes truly produce APO
refractor like images with little or no spherical aberation. This is
one of my favorite telescopes. I only sold it because I am now
building a 7" version. |
 |
16" F4.5 with a Meade mirror refigured by Steve
Swayze. This scope has since been modified to add DSC's and DOB Driver
II's for tracking. I still have this scope and probably always well.
I plan to rebuild the mirror box and rocker box to raise the trunions so the
balance is better. I'd like to get rid of the 20 pounds or so of
counter weights in the bottom of the mirror box. |
 |
This 8" F5 travel scope features telescoping
truss tubes that let the overall length of the scope shrink from 38" fully
open to 24 inches fully collapsed. It has an edmund mirror and a home
made spider. The altitude trunions are adjustable to balance the scope
with different eyepieces. |
 |
8" F6 with a Mark Harry Mirror. The tube
is made of walnut and birch strips, 3/4" wide and about 1/4" thick.
The tube is 52" long, 10 1/2" in diameter, and the OTA with tube rings, tube
clamp, and altitude trunions weighs in at 26 pounds. The rocker box
and ground board weigh 17 pounds. |
 |
13.1" F4.5 DOB with mirror of unknown heritage.
A clamp at the top of each column loosens to let the truss tubes slide down
into the mirror box. The height of the OTA in the collapsed position
is 38". Fully extended to viewing position it's about 60". This
OTA is surprisingly rigid in the extended position and holds collimation
very well. |
 |
My 16" F4.5 (rear) and 10" F5.6 (sold). |
 |
A collection of several of my scopes. At
the far left is my 16" F4.5 with a Swayze re-figured Meade
mirror. I still have and will probably always have this scope.
The third scope from the left has an 8" F4 noname mirror. This
scope was one of my favorites. Very portable, nice wide field views,
and decent images for a mirror with no pedigree. |
 |
A 7.1" F6 MakNewt.
since this picture, I have also added a dewshield. The OTA is made
from Sonotube veneered with alternating strips of Figured Walnut and Curley
Maple. This scope has uncanny images with far less coma than a
newtonian. |
 |
Similar to the scope above, this scope is an 8"
F5 with a Royce Primary Mirror. The OTA is baffled from the primary up
to just below the focuser then lined with black velvet to the top of the
tube. The top tube ring also serves as a baffle, extending part way
into the tube. |
  |
I custom built this scope for Bob Schilling in
the Summer of 2004. It has a 6" F9 Mike Spooner mirror and Protostar 1
inch secondary. The tube is baffled with 1/8" Masonite knife edged
rings that stand off from the tube wall by 1/8" inch. I later added
encodes to both axes before shipping the scope. |
  |
This is another collapsible tube DOB. It
has a 10" F4.3 Swayze mirror. The secondary cage is made of birch
plywood rings held together with 1/2" dowels. The cage is lined with
Black high pressure laminate (Formica). |
 |
This is a small 80mm refractor I built with a
Brandon triplet objective and a Williams Optics Focuser. The tube is
turned from thin-walled aluminum. The Dew Shield is made from 3" ABS
pipe. |
 |
I built this Alt Az mount to hold an Intes MK67.
It has Autostar DS Motors and the Autostar Controller. Very heavy duty
mount. It held the MK67 with ease and did a good job of finding
objects and tracking them. |
 |
Here is a small equatorial mount that I built.
The pier is made from 4" aluminum tubing. You can see that a Pipe Tee
was used for the declination shaft housing. Both the Declination and
Right Ascension shafts ride in Ball Bearings. The mount would have
benefited from a thicker pier and sturdier feet. |
  |
I made this little refractor with an acromat I
picked up on eBay. It is about an F8. I also made the Crayford
style focuser using teflon strips for bearing surfaces and a knurled shaft
which pressed against a flat in the focuser tube. It actually worked
very well. |
