Hi,

Thanks for the reply. I had another go. Starting with a formatted SD card and reinstalling everything all over again including all the index files. It finished at around 5AM this morning. Having sat through the entire night mainly watching it downloading index files you can imagine just how pleased I was when it didn't work again. It completely fails to solve and it cannot do polar alignment using the simulated devices. it makes little or no difference what focal length I use and it makes even less difference what exposure settings I use.

Note this is a straight install from the recommended download site (astroberry). I get the same results whether I use the astroberryos or a vanilla Raspbian with the ekos stuff added. It just can't solve any image no matter where I point the camera/telescope. In the attached screenshot I have copied the settings as far as possible from the image you attached and the result is the same: "Solver failed" as you can see in the attached screenshot.
