SATURN 2018

This season started with an outbreak close to Saturn's north pole!

These images were taken using a Celestron  C14  mounted on an Astrophysics AP900GTO mount and a QHY290M camera. RGB is done using a set of Chroma Technology RGB filters on a Starlight Xpress Motorized filter wheel.  Methane band images are done using a Chroma Methane Band filter (889nm  18nm bandpass).   Amplification is done using an Astrophysics Convertible Barlow working at 2.5X.

Image acquisition was done using  Torsten Edelmann's Firecapture 2.5 software.  All images are NORTH UP!    Processing was done using AutoStakkert! and Registax.

I had close to perfect conditions this morning.  Seeing was perfect but I had to deal with some clouds during the middle my RGB run.

This is an image of a stormy Saturn.  The Polar Storm is very bright and seems to have spread out!  There is a bright reddish EZ storm.  This storm is very prominent in the R channel.  There is another small storm in the temperate area south of the Polar Storm.

The Polar Hexagon and the Polar Vortex is distinct in the IR image.

I wasn't expecting much today.  Seeing was excellent but transparency was very poor due to clouds.   It was a good thing that I did not give up because I was really tempted to go back to sleep.

I was surprised to see that the Polar Storm has brightened!   I was expecting it to be very low contrast now but it seems to be alive again.  The polar hexagon is very low contrast in this image.

I had a very frustrating imaging run today.  The sky was partially cloudy with a lot of fast moving clouds.   I was only able to get a few data before the sky became overcast.   I would have gone back to bed but Saturn's Polar storm was visible this morning.  Seeing was excellent!

The Polar Storm is just past the CM on this image.  It is very faint and low contrast probably because of the quality of my data.  Note also another white spot on the STeZ before the CM.  This feature seem to have a similar size to the Polar Storm.

The sky was mostly clear when started imaging.  I was so engrossed with my computer screen when all a sudden, it started to drizzle!  In panic, I had to cut short my imaging run!  Seeing was good though.

The remnant of the polar outbreak is distinct in this image.  It is still a white spot.  The Polar Hexagon and the polar vortex is well resolved.

I had a late start with Saturn as weather here had been horrible.  Seeing was surprisingly excellent this morning.

The Polar Hexagon and Polar Vortex are well resolved.  Note the bright EZ spots which are prominent in the Red and IR images.  There are also small bright spots on the NTrZ.
