Please find image of Jupiter taken on the 14th @ 1:09UT. Seeing was very good after
The rain had cleared up around 23:00UT. Amazing amount of details especially the
Row of white spots,couldn't see via the telescope however.

Fair seeing for the altitude. A JPG and GIF again covering 20 minutes.

I have attached a set of images taken before dawn on the morning of 14 April 2006. These images were taken with my 25cm newtonian at f35 and a Lumenera Lu075M camera (2x2 binning). Schuler filters were used for all except for the methane band image which uses a Custom Scientific 889nm 18nm FWHM filter. Seeing was good, for the first 2 sequences but the fog became so thick that I had to quit imaging before finishing the 3rd image sequence.
There are 3 sequences seperated by approximately 30 mins between the start of the red images.
In addition to the RGB set there is a false colour Methane/IR/UV for the first and second sequences (labeled MIU). I have also processed the RGB frames with a contrast enhanced red frame and grouped the 3 RRGB frames inb the lower right of the image.
The GRS is visible just as it is rotating out of view. Oval BA is prominant in the red/IR/methane frames and there is a prominant white spot at the edge of the NPR which appears to be rotating with the planet. It is most pronounced it the red and IR but perhaps only slightly in the methane frames. Also, there is a long band of brighter material that seems to run above (S) this spot, preceeding it and running back to the following limb. It is most eveident in the first sequence and appears to be red or tan to me in the RGB frame.
Do either of these features warrant any particular attention?
I have 2 other sets of images that cover this region over the past month and I will try to put a comparison image together in the next few days.
Image processing will be a slow process for the next 2 months or so (as if it isn't slow aready), but I will only have limited time to process while work ties up too much time. I will distribute images as soon as I possibly can.
Any questions and comments are welcome.
