The comic shows Megan and Cueball being alerted by a 'Sky Alarm' that a 'cool space thing' is happening. The alarm is triggered when a relatively interesting astronomical event occurs, for example, the Perseid meteor shower and blue supermoon that happened recently. Randall remarks in the caption how he wants this device and wishes it existed. Cueball and Megan (and by extension Randall) feel that they regularly miss events they'd like to see, and such a device would help prevent this.
The title text further specifies that he would want it to activate even for more common sky-related spectacles, such as interesting clouds and nice sunsets (which still can be very beautiful). In short, it would help its owner to not miss interesting outdoor sights.
Most recently before this comic, Randall referred to cool sky phenomena in 2971: Celestial Event. Quite a few such references preceded this (such as the aforementioned Perseid meteor shower), so they may have been on Randall's mind.
