Mauna Loa (a sister mountain to Mauna Kea) shows some of the same information as Mauna Kea in a different format plus more information about the Moon.
The outer 24-hour dial moves like that on Mauna Kea except in this case it has the time of the Moon's meridian transit at the top ("Moon-noon"). Unlike solar noon, this changes by about an hour each day and moves all around the clock. The small gray Moon disk on the outer ring indicates the current 24-hour time. The gray semi-circles mark the times of moonrise and moonset; the most recent event (rise or set) and the next event are shown.
The large moon image at 6 o'clock shows the Moon's current phase, in a display like Chandra's. Unlike that display, it does not rotate to show the orientation from the observer's position (this is a more standard view as you might find on a moon phase chart).
The dial at 10 o'clock shows the local apparent solar time (sundial time for the current longitude). The local apparent sidereal time is shown in the dial at 2 o'clock. As on Mauna Kea, the green triangle indicates UTC.
In ambient mode, the same information is displayed, but with different colors to save energy.
