Raspberry PI HQ Camera

General

The Raspberry PI HQ Camera is supported via the indi_rpicam server, however there are some issues with exposures.

In order to take long exposures, an initial throw away exposure must be taken. The throw away exposure must be the first exposure taken after starting the indiserver process.

• 1 second initial exposure allows up to 1 second exposures
• 2 second initial exposure allows up to 6-7 second exposures
• 7 second initial exposure allows up to the max exposure of 200 seconds

indi-allsky will automatically take a 7s initial exposure to allow maximum exposure times.
