Evening Tent Talk Presented at the 2002 Stellafane Convention
Friday night August 9, 2002
Good evening, my name is Al
My company is Yummy Vue Optics
I have been researching advanced materials and techniques
for amateur telescope makers, that are low in cost and easy to work with.
I Asked
How many of you have a machine shop in your house?
Only a few people responded positively.
How many have an optical shop in your house?
Only a few people responded, and some were the same people.
How many have a kitchen in your house?
Most people responded positive.
Gee a lot more of you seem to have kitchens then the others.
Telescope tubes-
Gingerbread tubes Vs Cardboard tubes
Today we build telescopes out of cardboard, but not houses.
You have all seen gingerbread houses, but have you ever seen a cardboard house?
If they can build houses out of gingerbread, why not telescopes?
I also have developed a new type of low gloss frosting for Internal light baffles.
Insulating qualities of gingerbread.
Gingerbread is a better insulator then Metal and lighter. This allows for a tube the reaches thermal equilibrium faster.
In assembling the Optical Tube Assembly a special tool is used for preparing the two part adhesive system
The adhesive is made from powdered sugar and egg white.
You can prepare the egg white without an egg separator, but it is much easier and you get better results if you do use one.
New Optical parts
Silica Vs Carbon based optical system
You have all heard of pure carbon optical elements.
They have some draw backs, The are very expensive, and very difficult to work with, due to the hardness, but the women really seem to like them.
Instead of Diamond, I am using a low cost glass alloy of two carbon compounds, Sucrose and Glucose.
Sugar Glass Alloy
Let boil till 300 f degrees or sounds like breaking glass when a drop is placed in cold water. Remove from heat, pour into forms and molds.
If you want it to be clear don't put any food coloring in it. Otherwise add:
If you want it flavored add:
Grinding can be done with kosher salt and table salt, instead of expensive carburundum and cerium compounds.
The specific gravity of Silica glass is 2.21
The specific gravity of this sugar glass alloy is 1.58
It is 29% Lighter than Silica glass
This allows you to build a telescope, that is lighter in weight, easier to transport and one that reaches thermal equilibrium faster.
Out of these mechanical and optical components I have two demonstration models
The Tonto, With frosting
And if you live in an area where frosting and dewing is a problem
Then use the Kitchen Ranger, which is the frost-free model
The Mount
The mount is an alt/az fork mount made completely of the same sugar alloy, except that it is lubricated with vegetable oil to keep it from sticking.
Different f 's of eyepieces
Nibbler type 1 eyepiece
.f is for focal length and flavor!
Do you have trouble telling your eyepieces apart in the dark?
With Flavored eyepieces, all you have to do is just lick them, to tell which ones is which.
Blueberry 32 mm
Cherry 12 mm
Lemon 26 mm This model I had some trouble with, it is a copy of design taken from a Russian model, and never seems to work right
Lime 4.5 mm
Which would you rather drop? A $400 Nagler, or
something you can whip up in your kitchen for a buck?
In Conclusion
These telescopes have advantages and disadvantages over one of our previous research instruments the LEGO scope
The one main advantage is that the entire telescope and mount are edible, but it doesn't fold up as easily as the LEGO Scope does.
Another advantage is that these telescopes are completely biodegradable. Take a good look around this place. The hillside is just covered with old telescopes. It will take a combined effort of most of you here to clean up this mess. If they were all Yummy Vue's we would not have to worry about cleaning them all up on Sunday, nature would do it for us.
Thank you.If you would like to see a Tonto, you are Invited tomorrow morning to the lawn in front of the Pink clubhouse to see a Tonto, taste some lens and get a free sample of a Newtonian made out of figs
I call up Judy
I am Al, and this is Judy. We are the Rifkin/Allens of Yummy Vue Optics
Ask AL and Judi Nagler to stand up.
They are Al and Judi Nagler of Tele Vue Optics
Ask Al Nagler to come up front.
Presentation
Presentation of a Cherry Nibbler to Al Nagler
We both make very sweet eyepieces and telescopes, but if you have a choice get his.
Al, you make some of the most cherry eyepieces that exist and have changed the way we view eyepieces and use them.
On behalf of myself and the rest of the people here at Stellafane, I would like to present you with a Yummy Vue Eyepiece, serial number one, Nibbler type 1 Cherry eyepiece.
