The programs are as follows:
2. BoxGrid
This is a transparent, rectangular grid of variable size and resolution (controllable using sliders on the window edges) for determining the location and distribution of objects in a digital photograph. Author: Bill Smith |
3. GunSight
This is a transparent "gunsight" style widget with a variable geometry sight(controlled by sliders on the window edges) for use with webcams and ccd cameras to assist manual guiding on a target object. Author: Bill Smith |
4. RadGrid
This is a transparent, radial grid of variable size and resolution (controlled using sliders on the window edges) for determining the radial location and distribution of objects in a digital photograph. Author: Bill Smith |
5. Polaris
A program that shows where the star Polaris is in relation to the true celestial pole at the current time and date (when viewed through an inverting telescope). It can be used in conjunction with a polar scope that is mounted on a non-driven axis. Suitable for any longitude. Author: Bill Smith |
6. StarMicrometer
This program creates a stellar micrometer that can be used in conjunction with an astrocamera to measure angular separations and directions between pairs of stars visible on-screen. For this purpose it also contains built-in calibration procedure. Alternatively, it may be used with photographic images to determine relative positions. Full documentation provided.
