Paul McNabb founded the mirror lab in 1997 in order to create the best amateur telecopes possible. Inch for inch our mirrors surpass store bought or commercial grade scopes.

Ron Jones AKA the figurer is about the best mirror maker this side of the mississippi. You can see things in his 8 inch mirror that would impress a takahashi devotee.

Make your own mirror shipping box
First cut three styrofoam squares the same dimensions as your box. Use two inch thick styrofoam. You can use a steak knive or a hacksaw. You can get the stryofoam from Home Depot, Lowes, or a crafts store like Michaels or Joanns. You want to make sure there are at least two inches of foam between your mirror and the box, above, below and on the sides.
With a magic marker trace a circle around the base of your mirror on a piece of foam.
Cut the circle out with a steak knife. Be careful not to break the styrofoam.
You want the mirror to fit snuggly in the hole with with no gaps. It's also a good idea to cut one of the corners off the center styrofoam piece. This makes a nice place to get your hand in when you are handling the mirror.
The bottom piece of foam.
Next the piece with your mirror. Note for larger sized mirrors (10 inch and up) you'll probably want to put the foam in first and then set the mirror in.
Lastly put the top piece of foam in. If there is a gap between the top piece of foam and the box top you will need to add more layers of foam or other packing material. The goal is to keep the mirror from moving around in the box. The box should be packed tightly.
