2. Field of View Timer
This small utility provides a timer that can run on any
computer near the telescope and time the passage of a star
through the eyepiece field of view (FOV) when the telescope
drive motor has been turned off. When the timing is stopped,
the effective FOV of the eyepiece assembly is computed.
Basic-code listing and .exe file included. Simple but useful.
