I was up at Tara this morning, there was a perfect sunrise and I got a good few photos, not sure how sharp they'll be because I couldn't use a tripod (would get in the way).
The alignment is still very spectacular nearly two weeks later as I had guessed, I arrived about 7 or 8 minutes after the sun cleared the horizon and almost the whole backstone of the chamber was lit up for around 3/4 hours before the light slid off down the right side of the passage.
Will post some pics!
