<h6>What You Will Need to Make a Refractor Telescope</h6>


<p>To make a refractor telescope, you will need some basic tools and materials. Here is a list of what you will need:</p>


<ul>


<li>Glass blanks: You will need two glass blanks of suitable size and type for your lens. You can buy them from optical suppliers or make them yourself from window glass or plate glass.</li>


<li>Abrasives: You will need various grades of abrasives, such as silicon carbide, cerium oxide, and rouge, to grind and polish the glass surfaces.</li>


<li>Tools: You will need some tools to shape and hold the glass blanks, such as a tile saw, a glass cutter, a pitch lap, a polishing pad, and a lens holder.</li>


<li>Testing instruments: You will need some instruments to test and correct the lens, such as a spherometer, a Foucault tester, a Ronchi tester, an interferometer, and an autocollimator.</li>


<li>Mounting materials: You will need some materials to mount and install the lens, such as a lens cell, a tube assembly, a focuser, a finder scope, a dew shield, a diagonal mirror or prism, an eyepiece holder, and other accessories.</li>


</ul>


<h7>How to Make a Refractor Telescope Step by Step</h7>


<p>Making a refractor telescope is not a quick or easy project. It requires patience, skill, and attention to detail. However, it can also be very enjoyable and rewarding. Here are the main steps involved in making a refractor telescope:</p>


<ol>


<li>Design your lens: You can use the Excel spreadsheet programs on the CD-ROM included with the book to design your lens according to your specifications. You can also use one of the prescriptions provided in the book or find one online.</li>


<li>Grind your lens: You can use a tile saw or a glass cutter to cut your glass blanks to shape. Then you can use silicon carbide abrasives to grind the glass surfaces to the desired curvature. You can use a spherometer to measure the radius of curvature of each surface.</li>


<li>Polish your lens: You can use cerium oxide and rouge abrasives to polish the glass surfaces to remove scratches and smooth out irregularities. You can use a pitch lap or a polishing pad to apply the abrasives evenly on the glass surfaces.</li>


<li>Test your lens: You can use various testing instruments to check and correct the optical quality of your lens. You can use a Foucault tester or a Ronchi tester to detect and correct spherical aberration. You can use an interferometer to measure and correct wavefront errors. You can use an autocollimator to measure and correct coma and astigmatism. You can also use color filters to measure and correct chromatic aberration.</li>


<li>Mount your lens: You can use a lens cell to hold and align your lens elements. You can use spacers and shims to adjust the spacing and rotation of the elements. You can also use baffles and black paint to reduce stray light and improve contrast.</li>


<li>Install your lens: You can use a tube assembly to house your lens cell and provide structural support. You can use a focuser to adjust the focus of your telescope. You can use a finder scope to help you locate objects in the sky. You can use a dew shield to prevent dew formation on your lens. You can use a diagonal mirror or prism to redirect the light path for comfortable viewing. You can use an eyepiece holder to attach your eyepiece of choice.</li>
