|Description ||Avebury by moonlight
|Just.Simply. Gorgeous. Almost surreal... fairy-like... wow! Congrats!!!|
Bright Blessings and happy Imbolc to you all
|Superb.The way Avebury should be seen.Magical.|
|Angie, there also appears to be one to the right of the rightmost stone. I don't know what they are but suspect they are the result of manipulation. The stars are blurred indicating a time exposure but the moon is sharp, this suggests it was photographed and added later. He may have tweaked other aspects of the picture too, the bits in question look like slices that have moved, move the top one along its axis to the right and the shadows match up with those of the stone. This applies to the others too - still no idea why they are there.|
|This pic is awesome, and though I have viewed it many times before, I've only just noticed those two angled lines protruding from the top of the stone. One seems to stick out on the left, and the other on the right.
What caused them, and how did Tom (technically) get this wonderful picture?|

|Angie & Pat,
I have a 15x18" enlargement of this image downstairs in a frame, taken from a medium format slide. On this the moon is greyer and less distinct so I think Tom has cleaned it up but it's fundamentally a genine photo. I think the funny lines are a security feature as it is quite a popular image with buyers. The print is for sale along with other prints of Tom's best photos that I'll be listing in the shop.|
|Yes it is a great photo. There are flashes on some of the other stones so I reckon it was done like this. He set up the camera on a tripod then opened the shutter on B setting- ie it remained open. He, or an assistant, then walked to the distant stones and fired flashes at them. Then several bursts at the main stone. It must have been trial and error and I would guess that there were other attempts made which were less successful. The time lapse is shown by the movement of the stars, but why is the moon not showing similar distortion? Must have been added later. I don't know what the strange lines are on the main stones, but can't see how they can be security related. As Kelpie suggests - its manipulation and they are out of register slices. Pity - as it does weaken the final image.|
|Interesting comments above. The moon is definately added, it is rotated about 90degrees clockwise with respect to lines of declination (the short arcs made by star trailing are alwys parallel to lines of declination). Am also a bit puzzled by the stars themselves, I cant seem to recognise the constellations. Is the piccy flipped R-L ?|
|Have done some analysis of the piccy and it looks as though it was taken on or about 26 September 1999, at around 8.30pm, looking towards azimuth 75 degrees ENE. The constellations are those including Auriga left of the stone and Aris and Cetus to its right. The bright 'star' R of the stone, just above center, is the planet Saturn. The moon that evening was off-frame to the right but was indeed near full. The fly in this particular ointment is that the planet Jupiter, rather brighter than Saturn, should be visible rather below where Tom has his moon. Maybe he blocked it out.|

|Thanks for your favorable comments, as well as your constructive criticism. You have indeed gotten most of the details correct: I'm impressed that you (mostly Thorgrim and astronomer) spent so much time researching how I might have done it. The artifacts you mentioned are the result of my scanner...but I left them there for security purposes (a kind of watermark). I don't actually recall when I took the photograph, although 'astronomer' must be pretty close. I do recall it was late at night (10pm - 1am), and it had to be in July/August, since I was teaching astronomy/photography at the time, and would have been in college in Sep. I was looking ENE, but I don't recall the configuration of the planets. The moon was doubled-exposed, as you acknowledged...the exposure for the full moon is equivalent to that of a daytime exposure for the side of your home...after all, the sun lights up the moon at about the same distance as your home! Thanks for your comments, and Merry Christmas!|
|Hi Tom. Its just one of the things we amateur astronomers do when we forget to write notes re our piccies of the sky. Gets to be a habit.
The previous month, 29 August just about 11.15pm would also fit. Moon was 90% full off to the right. Saturn was at a sort of standstill until end of September (on 31 July Saturn was near to but not quite in the right spot) but Jupiter still should be on frame just below your moon.|
| Tom, thanks for a beautiful photograph.|
| SUPERB !|
