    3 years of time lapsing!

    Next month, the Herefordshire Astronomical Society is holding a public open day to commemorate the 50th anniversary of the first moon landing. I have been invited to do a couple of talks on astrophotography and time lapse imaging. As part of the time lapse talk I have put together a video of my time lapse clips, animated star trails and holy grail time lapses that I have taken over the last 3 years. I have done a few calculations and the movie which lasts about 21 minutes was shot using over 31,000 images taken over a total period of 11 full 24 hour days which is then condensed into a total of 21 minutes. The time lapses were shot at several locations including
    Hereford
    Eardisley
    Hergest Ridge, Kington
    British Camp, Malvern Hills
    Grwyn Fawr Reservoir, Brecon Beacons National Park
    Nidd Gorge, Harrogate
    Brimham Rocks, North Yorkshire
    Fewston Reservoir, North Yorkshire
    Ribblehead, Yorkshire Dales
    Thornwick Bay, Yorkshire Coast

    The video can be seen at the link below in HD and 4K

    Damn that's gorgeous! Forgive my language but ... damn!

    The contrails dissolving at 5:20
    The "rushing water" clouds at 5:57
    But I think my fave was the pan encompassing both hemispheres at 17:00. You can see the starfield rotation switch slowly from counterclockwise to clockwise.

    Question: At 17:15 a string of lights comes in from the right. Are those all satellites, moseying single-file?

    You can use damn if you like as it is quite appropriate as a couple of clips were filmed by a dam! In answer to your question, they are satellites (geo stationary I believe), they actually start to appear at 16:58 (check the lower right of the screen in the time lapse). The apparent number of them is due to the way the time lapse was being controlled by the Timelapse+ view "Holy Grail" intervalometer, at that time of night it was taking one 20 second exposure every 30 seconds so there was a 10 second interval in between each shot
    Best wishes

    Hrm. They can't be geostationary, or they would remain fixed relative to the ground.

    Camera was panning, iirc.

    Yes. Which is why I said they would be stationary wrt the ground.

    Well, I think they are satellites of some type

    Those shots of the Nidd viaduct sparked my recent obsession - with disused viaducts. I've managed to cross that one, the ones at Naburn, Newton Kyme, Conisbrough and Stamford Bridge, all on foot; plenty more to go yet. Thanks!
