Has anybody tried something like this https://www.amazon.co.uk/Oregon-Talking-Countdown-Timer-Digital/dp/B01N419H1F/ref=sr_1_1?ie=UTF8&qid=1494758018&sr=8-1&keywords=Oregon+Scientific+KD500+Two-in-One+talking+countdown+timer+and+digital+clock to give them a talking countdown before making an observation or starting an averaging mechanism for pre-computed celestial. Does it go ten, nine, eight, etc, two, one, zero? The customer reviews aren’t much help. DaveP
