the thames boat- winterwonderland saga seems like a massive extended slide. its been ongoing for weeks and has led nowhere yet.
please summarize the point of it in one or two short sentences or just call me a troll too. I have been tempted to filter you and I will if you dont explain its purpose and aim.
Stellarium is a free open source Astronomy program for Linix windows and Mac .
It gives a realistic Planetarium type view of the sky at a configurable place and time .

After reading your posts more carefully I had to conclude that this is not a slide , nor is it Boatshit , obviously not mere Prattery.
Also there is an obvious rude shill on this thread trying to manufacture a consensus. Its not working for me though. I hope someone can find a good use for the nifty astronomy app Stellarium.
Stellarium view
facing south in London on 5th January 2014 at 11pm
facing south in London on 5th January 2014 at 11pm ish without constellation lines and labels - and one with azimuth grid to show elevation above horizon
facing south in London on 5th January 2014 at 11pm ish
stars limited to magnitude 4 - eliminates fainter stars - star name labels off

sword points due south on horizon.
Other times , dates and orientations available from Stellarium.
Configure your own view with the extensive range of options.
i think that pic shows canis major stars pointing due south not orions sword.
view from hungerford bridge
looking south on 5 jan 2014 at 10 .pm
sword of orion pointing due south on horizon
5 November 2013 from the same position
at 10pm with azimuth grid and without.magnitude limited to 4
the program free open source and is very easy to use. It is simple to tweak the location and time so that you find a match with stars that show up in an image.
You can also set the atmospheric attenuation or filter the display of stars to a magnitude (brightness) level.

Online version of Stellarium app
https://stellarium-web.org/
There are also mobile app versions available.
you can use this to track the movements of Venus or Orions belt over any target dates you choose. and the azimuth grid can show the elevation of items above the horizon line.
The application version of Stellarium has more features than the web version - for example can filter sky objects by brightness (magnitude)
However both versions display the night sky as if projected on on a planetarium dome. The display is virtual 3d projection of the sky as seen from the observers point of view . This view has an interctive UI and one can look in any direction of the compass , as well as up and down (elevation).
One can define the observers location with longitude/latitude coordinates.
The exact time of the view can also be set or changed quickly .
Planet ,star and constellation labels can be displayed or not and grids and overlays can be applied. For example the path of the ecliptic- the apparent path taken throughe sky by orbits of the planets.
stars enhanced in pshop with threshold .
Is this the right image that I am looking at - I cannot see stars in any other pics like LisaMi6
tried messing with curves and threshold on the original png but no success in bringing the stars out
Orions belt becomes more parallel with horizon only as it is setting in the west some 3 or 4 hours later at about 3am- in the hungerford brige view from 5th Jan 2014
I cannot find stars when I manipulate the curves and levels in NSA_Traf_CAM_LONDON2847.png
My harsh threshold star image was made from the color enhanced jpeg version from this bread
how orion appears
2013 jan 5th at 10pm
2013 feb 5th at 10pm
2013 march 5th at 10pm
Orion - 2014 Jan 5th at 10pm,11pm ,midnight
typo i meant 2014 jan 5th
thats right . I am not a photoshop expert but I could not find stars when i manipulate the original png of the Trafficam pic
cannot find stars when i manipulate curves and levels in NSA_Traf_CAM_ROT2.png
2nd try -i cannot see stars when i manipulate curves and levels in trafficam png
Aha I did find stars in the other png NSA_Traf_CAM_LONDON2847.png
second attempt NSA_Traf_CAM_LONDON2847.png tweaked to reveal "stars"
NSA_Traf_CAM_LONDON2847.png tweak 3
Undiscovered stars learned.
there are two high tides each day and the same constellations come around daily and the time a particular constellation is for example due south varies by only minutes each day.
In central London if the weather allows one to view stars in a clear sky only the brightest .
stars will be visible due to light pollution.
The constellation Hydra is certainly visible due south in the winter months but I have not been able to find a good match as yet with Stellarium and the Trafficam Pic
I am here every day but only post if I have something to say.Pattern matching a picture to sky map is hard. BTW Stellarium allows one to view the sky in real time or in accelerated time.
Maybe other anons would like to try out
