Mages, Astral Vision and Long-Range, How does it work? Options

[Perssek]

Hey, guys (and girls), I have a problem here.

I´m GMing our first SR2 after a long time (last one was five years ago, I guess), and we had an incident were I had to rule something I couldn´t find in any book.

Let´s see: the team was about to kick some go-gang ass in their own turf. To do such, they did some undercover recon on the place for weeks before, gained the local neighborhood trust and then layed an attack plan.

Problem was, one of the key players (a sniper adept) couldn´t go to the session where the shooting started. So the mage had to trade places with him, since he was the only one that wasn´t affected by range. He sat at the sniper´s nest, a 10-stories building that gave full view to the go-gangers lair entrance. He was armed with his mumbo-jumbo and a nice low-light optical binoculars (so he could aim at LOS without problems).

But when the crap started to hit the fan, the streets lights went off, and he had trouble finding his targets. Then he switched to Astral Vision. And here comes the problem: Could he see astrally trough the binocular´s amplification?

I ruled that he could - the BBB don´t say anything against, but I´m still uncertain if it´s legal or not.

What do you say?
