My pleasure. :thumbs:

Should have a set from the D300 soon when I get them processed.

Any idea what that jumble of pixels under Polaris might be? Could it be CA? The lens is my Nikkor 20mm f2.8D AF @f3.2.

Last night went to Cartmel. The Priory is a very distinctive landmark which is very prominent in the village centre. Over the years I have worked on the structure of the priory several times, from the drains to the belfry and leadwork on the roof, I even helped install the 'new' Organ back in the sixties. So I know Cartmel Priory pretty well.

This is our second batch, the first batch was dominated by too many trees.

The batch contains 54 exposures. I was a bit troubled by passing cars lighting up one tree which looked wrong so I chose a nice exposure and layered it to obscure the bright tree.

Nikon D3, Nikkor 20mm f2.8, F3.2@20seconds, ISO 1600.

Specially for JK one chosen exposure without the star trails.

Just for interest, this is the output from the StarStaX software which I used to create the star trails. I wasn't happy with the brightly lit tree or the red light by the Cromwell door of the Priory. The tree had been lit by several passing cars while I was making the star trail stack exposures. The red light was me showing Christopher the bullet holes in the door made by Cromwell and his men when they attacked the priory in about 1645 during the dissolution of the monasteries. There are bullet holes which burst through the heavy oak door and can be plainly seen.

I layered a much cleaner image over the star stack image and cut away to reveal the star trails and other bits that were good.
