My most recent picture of Saturn was captured on Sun-3-Apr using a humble Philips SPC880 webcam (and an 8" SCT!).
Now as the planet is low in the sky, we see it through a thick layer of our atmosphere, which adds more turbulence and dispersion (colour-splitting), as can be seen from a still from my video stream:
But we can mitigate these effects by taking a large number (300 in this case) of short exposures (1/25-sec) and processing them in RegiStax (or IRIS), to yield a surprisingly clear image:
Now Keith and I will be demonstrating how this is done during our presentation at the 3-May meeting...
For those interested in imaging and image processing with DSLR, CCD, webcam or film.
