Re: Ugliest Scope Contest!

Posted By Ed Jones
How about the ugliest primary mirror? I had some condensation on my mirror and wiped it gently with a tissue, the coating came right off! On the bright side (pun intended) the silver hasn't tarnished after more than a year now.

Interesting design

Posted By Ed Jones
Here is a design that some may find interesting. I guess Celestron is making a 20 inch design similar to this. I scaled it down and and was able to find off the shelf lenses for the corrector that will work. All you need is a spherical secondary and a elliptical primary. What do you think?

Hey you know I got out my spanish dictionary and translated the spanish version of the national anthem back into english, it's not what they say:

Star Spangled Border

Jose did you see
All them folks on TV?
Not a red white & blue
Only spanic flags in view!

As we walked in moonlight
Crossed the barbed wire at night
No border guard with searchlight
Nor was a minuteman in sight.

Here there’s jobs everywhere
No tax forms to declare
And we know what to do
If a cop should stop you

So here’s what their senators and congressmen doth say
“We’ll vote the way you want if the wind blows our way.”

New record set

William Herschel built the largest Herschelian but second place now goes to this scope built by Kevin Frederick which is also the largest amateur unobstructed scope. Here's a pic of his 20 inch f/5.2 next to his f/8 Chief.

Need help with grinding tool

Posted By Ed Jones
Steel washers will rust and stainless washers are too expensive. Scott is right pennies are best. They are cheaper than ceramic tile and will not scratch since they are zinc (don't use the older copper pennies). They are great for lapping but not generating. It's also not illegal.

Need help, grinding 12.5

Posted By Ed Jones
Dave,
Since your tool is only 10 inches you'll need to use a longer stroke than normal to make it change. A normal stroke may do nothing to change the radius. Don't use too long a stroke though.

12.5 mirror grinding dilema

Posted By Ed Jones
David,
How high do you want your ladder or how portable do you want it? Mine had to fit in my car so I made it F/5. Otherwise everthing else gets better with longer focal length.
