Images of Saturn 2003 Home

The first image here is one of my first ever, taken with my ETX125 and remains one of my best.  I've been trying to better it for nearly two years.  Most of the other pictures were taken with my LX200.  I think this shows that seeing is more important than almost anything else in getting good images.

The ring system of Saturn was almost fully open in 2003, giving the best opportunity to image the divisions, but is now beginning to close.  The Cassini division is an easy target, but the Enke division is beyond the resolution of both my telescopes.  The Enke minimum is a dark part of the B ring and is a difficult, but possible, object to record.

The different colours of Saturn in the pictures below are not real.  It is difficult to know what the colour should be.  The differences are due to different colour balancing in the camera and/or modification in processing.

The first image below is the best image I've obtained with the ETX125 and is the oldest.   The rest are in reverse chronological order, so the most recent is at the top.

Saturn on 030319 20:22 UT This is the best image of Saturn I have obtained with my ETX125.   I was very new to imaging at the time and didn't make full notes as to what I was doing.  However I believe the following is what I did. I am very pleased to have captured the Enke minimum.
This image is upside down (i.e. south at the top) but I'm leaving it that way; it's prettier!

Saturn in the IR 031012 03:50 UT These four images of Saturn were shot in the infra-red on the same night as the image above. They are from different AVI files and I do not know why the A ring appeared so bright in the infra-red that night.
