The winter sky viewed from Castle Hill. Annotated.

I've wanted to do this for ages, but never managed to get a set of photos without gaps in to make the panorama. I now have a ridiculously wide-angle lens (12mm), with which you only need to take thirteen pictures; I can manage to take thirteen pictures without making a mistake, and here's the result. 20 second exposures, f/4, ISO 1000 on a D90.

Castle Hill has probably the clearest horizon in Cambridge, apart from the tree to the north, but Cambridge is quite brightly lit. You can see Shire Hall (obviously), New Hall, the University Library, King's Chapel and the tower of St John's.

That's lovely. What time was this, and how north was that tree? I get wonderfully clear skies on my journey home and would like to do a little star-spotting, so it'd be handy to have a reference if it's clear tonight.

That was taken at about 10:30pm on Friday, and the tree is roughly north-east.

I'm not sure how well the picture will print out, you might want to invert the colours. I have a couple of other versions in which I've done strange image-processing to delete the streetlight and highlight the stars, which I'll upload this evening.

Very glad you like it!
