Asteroid Observation Planner

This tool is designed to generate a list of asteroids to observe based on your location and horizon mask, for observation over two nights. Target magnitude is set to be between 16 and 19, but is user configurable.

Asteroid Visibility Checker

This tool takes your location, horizon and a numbered asteroid designation and returns if the asteroid is visible from your location as well as the best time to obsderve it.

GIF Animation Star Annotation

This tool imports a gif file, finds a star based on a 2MASS ID and applies a small circle to the gif animation. The purpose of this is simply to highlight a region of interest within a gif file.
