- newt20.zip 75271 bytes, DOS
Newtonian telescope CAD (Computer Aided
Design) program. It uses a GUI (Graphical User Interface) to design a
Newtonian telescope, and allows you to modify all the parameters. Capabilities
- Display a side view of a newtonian telescope.
- Modify all parameters like mirror diameter, diagonal minor axis,
focuser height, focuser inside diameter, tube inside diameter and thickness, and
- Use inches, centimeters, or millimeters as the
unit of measure.
- Calculate baffle size and placement.
- Calculate diagonal offset.
- Calculate fields of 100%
and 75% illumination.
A variety of formulae, etc, of
interest to the ATM.
- sixtests.zip 46 kb, DOS
uses a series of test measurements to compute the mirror profile errors, several
mirror evaluation parameters, and the resultant diffraction pattern. The author
Jim Burrows, who writes: "Comments,
criticisms, and cries for help (if needed) welcome."
This public domain file contains the generic
BASIC source code and the compiled EXE file for Jim Phillips' program
SPRINGCW.BAS, which calculates spacings for a telescope spring counterweight
system as described in Sky and Telescope, November 1999, pp 130-134.
- tex.zip 64556 bytes, DOS
Phillips' and Dale Eason's program for Foucault test reduction based on Jean
Texereau's method. For the latest versions of this software, including Windows,
Linux and Solaris versions, see
