The axis of our Earth currently points more or less at the star Polaris; at the time I write this Megastar tells me that
Polaris is at RA 02h, 31m 47.080s; DEC +89 degrees 15' 50.90", so slightly off the real celestial North Pole.

To capture the kind of star trails you see on this page you need a long exposure camera and a static tripod; then aim at Polaris or at a Northern region and capture images as long as you want and clouds do permit you.
Next just sum the captured frames in K3CCDTools with the 'if lighter' function and you got your star trails.
Of course you can do a similar thing in the Southern hemisphere.
All my deep sky images can also be viewed as an

Polaris nicely in the centre.

While camping along the Loire, France I noticed that I had a rather nice view at Polaris.
So I mounted my SC3 Colour webcam with 10mm SLR Photolens on a static tripod and hoped for the best.

In the centre is Polaris; the animation consists of single unprocessed frames with a 10 minute time interval.
The animation was made in K3CCDTools by using the Text Output Filter to add the time and the Export function to create the GIF file.




And here is another animation: [15Mb so be patient while loading: it is worth it !]
Processing: K3CCDTools to export to bmp; in Starmax I imported the bmps and did - Process Left Column - Processing - AddMaxLum and Savesteps,
which generated output bmps, which I imported in K3CCDTools to create the gif file.

Star trails instead of Perseids ...

Imaging Details: TV zoom lens at 10mm, SC3a b/w RAW camera mounted on static tripod; exposure 247 x 30 seconds
In the morning I found out that I had not captured any Perseids, but summing in K3CCDTools in if-lighter mode still yields a nice image.


Ursa Minor

Ursa Minor: the Small Bear. Also known as the Little Dipper.
Imaged from static tripod.





The upper image was processed with MaxIm DL 2.09 [demo version] to compensate the rotation, whereas the lower image was processed with K3CCDTools ['full frames';'calculate results' with the option 'If Lighter'] to show the rotation around the celestial North Pole.
