Saturn
Images from 2011 to 2019 showing the changing tilt over this time From 2011 to 2017 the ring faces had been opening up - and in 2018 & 2019 they began to close up again as Saturn commences to tilt back in the opposite direction. Click on the images..! 😊 |

A nice
image of Saturn & 2 moons where the tilt still provides a nice
perspective of the North Polar Hexagon. The image below
shows the rgb & constituent r, g & b images. |

The mono
image above points out a storm spot (white) on Saturn at the time. The image
immediately below shows how WinJUPOS is used to measure where this spot is in
terms of latitude & longitude (L3) on the colour (rgb) image on this
date. Below this
the next 2 images are also from that night. |

On 2 of the nights we imaged Jupiter at
Natimuk in Victoria’s West Wimmera we also imaged Saturn. Although the skies were excellent for imaging
there, the temperatures were freezing – literally J
- so we only imaged longer (to stay up long enough to capture Saturn) on 2 of
those 4 nights! This image (at 180% enlargement of the
capture scale) shows several small white spots. (small relatively, in
actuality they are of course very large when you consider just how large
Saturn really is compared to our Earth) These white spots (each one called a
“BWC” – Bright White Complex) are actually storms in the (visible) upper
atmosphere of Saturn. CLICK ON THE IMAGE! |

Above is a simple 2-frame animated gif of
Saturn from this night: in this you can pick up the movement of those white
spots. (BWC’s) This assists not only in seeing them but
also confirming that they are more than anomalies or artefacts created in the
capture &/or processing routines we apply by the ability to detect them
in more than one image capture. |

Another image above taken on the first
night at Natimuk with very little to see on this visible face of the planet. The image below this one displays the
colour image at capture scale as well as the individual colour channels (red,
green & blue) that make up the rgb (colour) image. CLICK ON THE IMAGE! |

Another good image outcome despite very
strong winds making it difficult to keep Saturn in the camera’s view – the images below this one being the
individual colour channels of the colour (rgb) immediately below. |

Saturn for 2019 where weather conditions for imaging have been very
unfavourable much of the time. |
