This drill stand must be the type that allows the drill to be reversed in the stand, so it can point upwards. We realize that the stand for the hand drill is an item that most people do not own, however it will be an investment and something that can be used indefinitely. The major tools are a variable-speed hand drill (best if corded) with a "stand," drill bits, hand saw, miter box and other basic tools including screwdrivers and wrenches. You will then purchase cardboard tubes, wood, nuts and bolts to assemble the telescope and construct the tripod. You will grind and polish three lenses-the materials are provided in the kit-see pictures to the right. You can definitely purchase a commercial telescope with superior optics, but this project is a learning project, to introduce you to telescope making. The 60-inch focal length of the objective is very long to greatly reduces optical abberations.
All of the lenses have plano-convex surfaces (flat on one side and convex on the other side). It has a single element objective lens (the front lens) and two, single lens eyepieces. This telescope is a simple Keplerian refractor. This kit contains the materials to make the objective lens and two eyepieces, as well as completed wooden "cells" to hold the lenses The completed 1.5 inch diameter refractor. As a class project, every student should be able to find some aspect that he or she can contibute towards the completion of the telescope. Additionally, we cannot provide kits for whole classrooms, so we ask teachers to purchase one kit and make it a class project. For this reason, we ask that your purchase of the kit be a serious consideration. And, it is very time consuming for us to create all the pieces provided in each kit.

#1600s telescope drawing manual
Review this page, the manual and the videos on YouTube, to see if this is the type of project that interests you. We hope to incourage individuals to learn and enjoy telescope making and observational astronomy. Additionally, the manual contains a plethora of celestial objects that can be observed with the telescope. The intent of this kit and instructions is to provide a means to build and learn the fundamentals of telescope making-to go through the whole process from start to finish. But, the materials for the tube and tripod are to be purchased and constructed by the telescope maker.
A few of the basic telescope components are also included, like the cells for the objective lens and eyepieces.
The kit includes the basic materials to grind and polish a 1.75 inch diameter refractor lens (with a clear aperture of 1.5 inches) along with two eyepieces that yield 30x and 60x. and Ken Graun have created a basic telescope kit for anyone wanting to try their hand at building a simple refractor telescope and explore the heavens. NOTE: Very limited quantities-PLEASE READ the statement below in ORANGE.Īlan Binder, Ph.D. This is NOT a kit of parts that you assemble-you make everything from the telescope lenses to the tripod.
