First of all, a special thanks to Ace and Goran!
I found The Merovingians fleet, and launched, but without luck.
The next day I decided to scan the inactive planet right next to his moon, in the hopes of there being an attack fleetsave going on. Lucky me.
Ace got a colony out there. Getting a moon there was a rather unlucky process (Must be Gorans littlefighters), getting rid of The Merovingians moon was on the other hand lucky (1st try).
Rest was just lock and load!

for too long. (the 8th round finally did the job). 
For what it's worth, defender still had a good 10+ hours out to the target & I don't think anyone was planning to sit on lanx for 10 hours waiting for a recall... 
(it's much easier to just pop the moon and have exact time... )
