I have invaded such a colony myself and it doesn't look too hard if you nuke the lower left, I know, but there is a prb with that.
Your nukes will fly to the nearest target, if you manage to nuke the lower left a little, the nukes will eventually fly the wrong way, and you will have to move too much to fire the missile in that direction, which will kill you at least once or twice. The only solution too this that you nuke at least one ring of lasers 360° and then attack the lower left, it's still a I love you man! considering you have to nuke the lower right too to get the nukes to fly to the defences near the dome.
I've invaded an exact copy of this colony, but it took around 300 nukes in the end, maybe if you invade it with a corp it's possible to take it with less nukes, I dunno
Oh Yeah MadAce, non of those slides are possible, you're sliding between too lasers which is impossible

and if you're idea was to nuke those exact lasers that are in the way to slide it your nuts lol, that's almost impossible to do, ALMOST though
