The barrel and round bottom base are figured walnut from the crotch of the tree. The eyepiece and column are cherry burl. The gears on the column are from transmissions and the bands on the barrel are steel with steel rivets. The mirror is 9-pt with the 3rd side a patterned dichroic piece of glass to compliment the object cell colors. The object cell has a few watch gear pieces, dichroic pieces, and other special pieces that Peggy has created.
