Mods, Please let me know if this is outside the scope (whoop's about the pun) of the forum.
I felt that the stars and night sky as well as our quest to understand it all is all nature hence the post, and its nice to put something different to Barn Owls (huge amount of new images from this last week on my blog & Flickr etc)
This shows 3 of the antennae that make up the 1 mile array at the Mullard Radio Astronomy Observatory at Barton near Cambridge. This is a 210 second exposure with 20 seconds of light painting on the radio telescope, some guesswork and the use of the camera monitor and histogram as a "meter" enabled some very accurate exposures in the end!

I had just noticed the banding on here myself, I think it's Flickr that adds further compression, a bit annoying really!
Yes, longer star trails are coming up later, I was avoiding posting a heavily computer manipulated image to start with, I shot a sequence over 3 hours and will run them all through startrails software later today.

Just watched Sky at Night, about Life in the universe, which I recorded. I wonder who will be the first to post an image of a genuine extra-terrestrial life form on NPN? Excellent image, can't wait to see more.

It's working for me Nigel, the range of colours in the sky is fantastic and beautiful too.
There does seem to be some slight banding running through the image which is probably down to the compression at this size, but no big deal.
It's a top class piece of work in my opinion and deserves to stay and your torch control is second to none

An interesting and strong focal point and the colours in the sky are superb.
