In reply to wilkie14c:
I’ve seen quite a few, the best ones being:
1. Just finishing the ridge and sticking my head through the window on Sgurr nan Gillian and seeing a broken spectre (freaked my mate out, he’d never heard of them).
2. Above the cloud line, with the main peaks of Aanoch Eagach and Ben Nevis range and my broken spectre appearing to float above the ridge
3. in a plane, the sun shining straight through one window, past me, and casting my broken spectre just above the planes wing in the other side.
