Tonight was the night with the best seeing conditions of the year so far.  Transparency and seeing was well above normal altough it could have been better.  I made imags over a period of 45 minutes with the Williams Optics barlow.  these images have been used in the animation (middle thumbnail).  Two of them are shown as individual composites (bottom two thumbnails).  I than made two images using the Celestron 2x barlow, which gives a longer focal ratio.  I had to stop the exposure speed to 1/19 sec. and limit the number of frames to have sufficient light for a good histogram and to limit the rotation blur of the planet (top thumbnail)

Here the images from the evening of September 30th,  (October 1 UT)
