Thanks, so all your reporting is a reduced RMS when calculated for multi star Vs single, which does no necessarily mean you will see an improvement in the actual image. It may be the case that multi star averages out the seeing and allows for shorter guide exposures and ensures guide commands are only issued when really needed but all I'm seeing being reported is that the RMS improves and therefore it must be better but no evidence from measuring something on the resulting images.
Will be interesting to see how this all progresses and if images are improved or it just makes people happy because they see a lower calculated RMS and a better looking graph!!
