How did NSG 20 find their targets at night?

[tcolvin]

This is a matter raised off-topic on Chris Goss' thread, because he has written a book about NSG 20.

There seems to be an assumption that NSG 20's remarkable night bombing was done visually and not with assistance from the FuS An 722 ZYKLOP that was used to direct the single-seat Ar 234s to the dive point with the right direction and height for bombing Remagen Bridge.

But I am now beginning strongly to question that assumption.
Surely no pilot of the single-seat FW 190 G could find 2 Lincoln's HQ in Winnekendonk at night from Twente over a distance of 100 kms.

2 Lincolns HQ & RAP occupied the big farmhouse on the outskirts of Winnekendonk at about 6pm.
German paratroopers were milling around in Winnekendonk for hours afterwards, without orders and uncertain as to what had happened and the location of 2 Lincolns and 3 Scots Guards whose Churchill tanks were in the town.

It took NSG 20 in Twente six hours until midnight to get a bomb delivered over a distance of 100 kms and dropped almost on top of Battalion HQ in Winnekendonk.

I would dearly like to know how they managed that feat.
FuS An 722 ZYKLOP looks like the only answer.

Does anyone have a view about that?

On March 2, 2 Lincolns and 3 Scots Guards broke through the last organised defences before Wesel.
The Germans were bound to react to this breakthrough with everything they had.
The only thing in their locker was NSG 20.
