Unattended system for sky watching

I hope this is the right forum to post this thread. Sometime ago I had come across a classified here for sale of an unattended system for sky watching which was based on Raspberry Pi (IIRC). It was built DYI and used open source code from github. Covered in a polycarbonate transparent dome with dew shield, it would take photos of the sky intermittently and make them available through a web-server. I am interested in building it or purchase it if it's still available (I can't find it in the classifieds). Can some kind soul point me to the ad or any other details that could help build it - or if the original seller is reading this - will you please contact me? Thank you very much!

Nm, I found the classified.
