    Cracking image Paul 👍 

    I quite like the use you're making of the single light. It works here and it did on the gate too. How many attempts did it take to place it until you got it spot on ?

    In fact it makes the background even more obvious that there's no real light pollution in the valley.

    @davew thank you!  Am very pleased with how the light works.  Gives a really different result compared to fully light painted foregrounds.   Quickly learn from mistakes.  Not too close to object, remember camera line of sight, start on dimmest setting.  All single exposures, may need a foreground exposure for dark nights.

    A short image/timelapse/music mash-up.  Cheers, Paul.

    Earth’s Orbital Motion around the Sun

    in Imaging - Widefield, Special Events and Comets

    This is a duplicate post from a competition thread.  I noted that @davew has done this and it enables replies to the post unlike the competition thread format.  We can discuss the merits of various chocolate snacks or even technical questions...  @James I note the intermittent lighthouse illumination didn't appear to impact your time lapse?

    A ‘Sidereal Day’ is the time taken by the earth to rotate on its axis relative to the stars, and is almost four minutes shorter than the solar day because of the earth's orbital motion around the Sun.  A celestial object therefore reaches the same position in the night sky earlier each day.


    This can be seen in the attached composite of 3 images of the rising spring Milky Way in the south eastern sky in March, April and May. Each taken earlier and earlier in the night, yet the Scutum Star Cloud is in approximately the same position.  See images for date and times.

    (Times are a bit approximate as its not set correctly on my camera and there was the matter of GMT -> BST!  Have also attached a rotated version for clearer viewing..?)

     

    Cheers, Paul.

    I recommend  the RASC Finest NGC Objects as a next step deep sky from Messier.  It is based more on an object's attractiveness rather than a catalogue like the Herschel List which has many unfulfilling 'ticks'.  Being a Canadian list is great for northern latitudes.  I have trawled through the Herschel list once, however keep returning to the Finest NGC Objects.

    A set of 9 stone 'cairns' high above Kirkby Stephen, Cumbria.  On the Wainwright C2C walking route.

    Surprised at the background lighting, some all the way from Darlingtion and Teeside.

    Pano is 5 portrait frames, each 4 x 8s subs at f2 and iso3200.  Prep in Lightroom, stack in Sequator, composite in MS ICE, finish in Photoshop.

    Canon 6D MkII, Sigma 24mm ART, Nodal Ninja pano mount.

    Cheers Paul
