2 or 3 luna secondarys

Is it possible to connect several devices as secondary? I have a mbk 15 pro 2017 and I have a mbk 12 2015 connected as secondary and perfect. Now I want to connect another mbk 13 2017 and thus have 3 screens at the same time. Is this possible?

@Mdmarc85 nope, as they state on product FAQ page:

Using Luna

Can I use multiple iPads or Macs with Luna?

No — Luna Display only supports one iPad or secondary Mac at a time, and one Luna at a time. You may, however, set up Luna to switch between iPads and secondary Macs using Office Mode → Learn More
