SATURN 2015

Saturn's rings are opening up more!    Things look quiet at the start of this season.

These images were taken using a Celestron  C14  mounted on an Astrophysics AP900GTO mount.  A Celestron Skyris camera is used.  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 2.0X.

Image acquisition was done using  Torsten Edelmann's Firecapture 2.4 software.  All images are NORTH UP!   The Skyris camera is controlled by a Thinkpad T520 through the USB port.  Processing was done using AutoStakkert! and Registax.

Condition was not good this evening.  The sky was hazy so transparency was low.  Seeing was very variable this evening.

No prominent activity in Saturn in this region.  The rings are slowly fading now.  The polar hexagon is obvious.  The EZ is bright in Methane band while the NEB is dark.

Seeing was good this evening. 

I was finally able to take a methane band image of Saturn!  The disk of Saturn is mostly dark in methane band because of the bright rings.  The EB seems to be bright while the band are dark in methane band.

The polar hexagon and spot are well shown in these images.  Note a dark spot at 64N just past the CM.  This spot is dark in green light.

I  got close to perfect seeing conditions! 

I have finally caught the 63N storm that other observers have imaged.  In the R and IR band, this is a dark spot.  In the color image, you can see the reddish wavy pattern surrounding the dark spot.

The polar hexagon is well resolved.  The edge is distinctly dark white the inside is light.  The center is dark in R and IR filters.

The NEB has a white band in it's southern edge.  Note the low contrast but slightly white feature on the NEB.   There seems to be a dark spot at the 44N area on the right.

Condition was good last night.  Seeing was a little unstable but I did not have to deal with clouds until close to the end of my imaging run.

It's a few hours before Saturn's opposition and the Seeliger effect can now be seen.  The Seeliger effect brightens the ring of Saturn because the earth is now perfectly between the sun and Saturn.  The ice particles of the ring give us maximum reflection the new next 3 days.

The surface of Saturn has turned pale because of the Seeliger effect.  Note the white band in the SEB.  The polar hexagon is well resolved.  Note the dark spot on the north pole in the IR image.

I  had a crazy imaging session.  The sky was mostly clear when I started setting up.  But when I started imaging, clouds started to roll in.  In fact, it was mostly cloudy today except in a 20 deg area around Saturn.  And it stayed that way for almost an hour.  Transparency was variable because of the clouds.

On most interesting thing in these images is a bright storm on the EZn!  This storm is clear in the raw images.   The dark polar spot is very prominent in the IR images.  The polar hexagon is also prominent.

Seeing was average this evening.   These are my first images of the season.

Nothing really noticeable on Saturn in this region.  The polar hexagon is still very distinct.  The bands are very distinct especially in IR.  No dark spots in this region.
