*Absolute time accuracy is essential**
to connect all the observations together
after the fact. Check
the time of your computer with many sources (phone talked
hour, different internet sites, ideally with a GPS). Its advised
to check the registered time right after and right before the
integrations, so if there is a drift, we can correct it by having
Beware of the dead time
between the images: if you manage an exposure time of 1
sec (for example), but have your camera takes 2 sec to read the
image, then there is a 67% chance that you miss the
dis(re)-appearance of the star. So it's better to have, for
example, a 4 sec integration, so you have 67% chance to get the
occultation in one of your exposures.
