Technical Details....... 27 x 30 second shots taken from 6.10am to 6.25 am, each every 35 seconds (so five second pause for memory etc - noise reduction OFF).
Stacked in GIMP using Lighten Only function.

I guess that you could have gathered enough light for the shot.....with fewer, thirty second exposures ?
But you went for the 27 shots...to achieve the coming circular 'dart board' effect trail of the stars ? ...
or am I on the wrong track here...ps...I spotted the north star.....Dj.
Ah.... good question, from a canny Yorkshireman David
The idea of the multiple exposures is to catch the star trails as they perambulate through the night sky. So 27 x 30 seconds is 13.5 minutes, why not a shot of 13.5 mins? Because the noise from a sensor CMOS or whatever is horrendous at that long duration. Hence take lots of little shots and stitch them together (or stack them).
I have worked out (tonight) that I can increase the frequency to 33 seconds for a 30 second exposure. The 3 seconds for the memory write. The 5 second pause in this shot can be seen as the black spaces in the star trails. If you were patient, you probably could count 27 shots.......
No, don't try it.
Many thanks for your interest David.
Best wishes from cold but clear North Carolina - Jethro
Gotcha' on the info thanks Jethro'..and the star trail blanks....Dj.
Great! LIKE! Gr., Roberto
neat one jethro ,you should try it with just one tree or a building in the center next time for the spiral effect,hope it was not to cold out when you were standing around waiting,as for the north star think it's the bright one!!!!!!!!
My brothers wife's cat is called Spot!
Thank you Roberto
You are 100% correct Tammo - I plan to but this was from my back deck while I went back to bed! If I did it somewhere impressive then I have to stand around getting cold! Now where is the fun in that?
And is a North Star Mike?
Best wishes y'all from a sunny but chilly North Carolina - Jethro
Aye, well t't cat lives only 300 yards from Scots/English border, is yon t't North enuff fer yer?
That explains everything now Mike
The center of all the action is where you'll find Polaris, when you're not cozy in bed that is, dear Jethro, so spot is a well chosen term! I was just out looking at it a while ago, then the clouds covered everything up. I am always hoping to see Orion in the SE sky. Have you ever seen the little dipper? I have not, too much moisture in the atmosphere here, even on a really bright star night. Fun photo - love the arching tree (O:
Jethro, Way back in the 70's aa were still a young laad, aa had a Canon AE! that used to tek grand photos of night skies and car lights, as far as I recall, aal the stars would be single points of light, yours are streaks of light - does this mean t't world is whizzin' aroond faster??
I was just sitting outside (9 pm, 42 deg F.) and saw three bright, wide meteors in no time at all, Jethro, which got me thinking about and wanting to see this photo again. Our sky has cleared after a rain and rainbow day. Orion is bright and beautiful. Just wanted to say Hi! (O:
Its supposed to be the best meteor shower in the next few days and I am located in the darkest place imaginable Suzi
Trouble is its pouring with rain from the heavens!!!!
You can't win them all.
I saw more meteors an hour ago, three in very close succession once - very special. Frosty here and clear, waiting for the next storm to pass through. Wishing you clear skies (O:
Last night was AWESOME Suzi !!
We stood in the street awhile after dark here in Ocracoke (NC) and got a great show, then about 10.30 we drove up the island to get some serious DARK!
We stood on the boardwalk to the beach and we were seeing twins fly over together. A magical experience.
It may be just as good tonight, but I think I am meteored out for another year!
I hope you stay warm dear Suzi - it gonna be 10C - 50F here or there abouts.
