Interesting how many variations we're finding.

What you describe is similar to cadenced exposure modes:

An alarm is set for a particular clock tick (here in a heliocentric timescale) and this acts as a governor on an otherwise undisciplined sequence of exposures, perhaps extending over multiple sessions.
