Some cameras perform well, but some apply too much video processing, making the data virtually useless.

			You can usually do an initial focus with the camera assembled on a desk. Point it out a window during the hours of darkness and focus on a building at least 50m away.

	You can do this using the RMS utility ShowLivestream instead of VLC, if you have already fully configured the camera and Pi as explained in the next step.

	Very precise timing is essential to processing the meteor data, so unless you are confident in your internet connection an RTC module ensures the Raspberry Pi always has the precise time, even when power or internet is unreliable. AliExpress sells a pack of 10 but they are inexpensive - maybe share the extras among other camera constructors in your area.		Very precise timing is essential to processing the meteor data, so unless you are confident in your internet connection an RTC module ensures the Raspberry Pi always has the precise time, even when power or internet is unreliable. AliExpress sells a pack of 10 but they are inexpensive - maybe share the extras among other camera constructors in your area. The AliExpress store lists two RTC modules, one labelled "DS3231 module" and the other "mini DS3231 module." Select the "mini DS3231 module" option; it is designed for the Raspberry Pi. It has 5 pins and includes a battery.
