The Pi camera module was fitted with a C/CS mount and a scope adapter, and was placed at the Newtonian focus of an f/5, Skywatcher Explorer 130 P-DS OTA Newtonian on a Star Discovery AZ, GOTO mount.
A Waveshare 5Mp Raspberry Pi camera module with a OV5647 CMOS sensor was used because the lens assembly can be unscrewed and replaced by a C/CS mount, or the lens itself can be unscrewed and a standard webcam scope adapter attached. A 1m ribbon cable enabled the camera to be mounted on the scope.

The Pi camera module will be implemented in AstroDMx Capture for Linux. However, Nicola is currently sorting out an issue with the ZWO SDK with USB2 and long exposures before a new version is released implementing the QHY cameras. QHY is already implemented, but the release is delayed until the issue with the new ZWO SDK is resolved.
Meanwhile, my simple Python program is showing that the Picam module has potential as a prime focus Lunacam.
