The light house emmisions have changed significantly sice the 1980 sighting in both power and bulb type so comparison is difficult.
If you use a night vision on the lighthouse it changes the carecteristics of the beam hugely, i'm not saying he was but if you take the time to go there at night and use one it looks very different and he had some form of nightvision with him that night (starscope).
Quote from the halt tape:
"And when you put the Starscope on it, it?s like(?) a hollow centre, a dark centre, it?s like a pupil of an eye looking at you, winking. And the flash is so bright to the Starscope that it almost burns your eye".
The star scope is now usless as the brightness has burnt it out (and yes i ruined my nightvision looking at the lighthouse). anything veiwed through the scope after this point is totaly useless as evidence of what was actually being veiwed
Was Halt using the damaged starscop to veiw the objects in the sky?
because if he was i can say with all certainty that veiwing a star through a damaged nightvision creates all sorts of distortions and "beam like" sprays from the light source, and costs you a new night vision
On the subject of the starscope it's claimed it picked up heat signitures from the marks on the trees?
Is it not more likey have just picked up the infa red reflected by the tree sap in the damaged areas of the tree, (does a starscop use an infa red emitter like night vision) yes i've tried it, in rendlesham last year, you can also pick up the infa red light being reflected off of flys (especialy if your standing in a big ole pile of dog poop)
Only thing i noticed was in the cold wether it take a good few hours for the sap to flow into the cuts, quicker in the summer (when the saps rising).
so that 1 night vision and a pair of trainers that little trip cost me
