Jupiter Oct 25th RGB and IR

Hi All,

Imaged Jup Oct 25th. It was crystal clear but the wind was very strong. This was the first night I have ever felt the need to lock down my dome following each time it had to be rotated.

The seeing was not good, about 5 to maybe 5 1/2 /10.

I am a bit surprised the images came out as good as they did, considering the conditions.

I have posted 3 RGB images and 2 IR images. Io and its shadow were in transit when I commenced this hour long capture session.

The red spot in the NNTeZ that merged with the white spot back in Sept is interesting in so much as it seems very bright in IR. I have marked the red spot in one of the RGB images. It is clearly visible as a bright spot in both IR images.

As I have only just acquired my IR filter I am unsure if the red spot was bright in IR previous to the merger or is bright due to the merger.

The SEB has virtually disappeared in the IR image as the activity within it has more or less ceased.

Thanks for looking.
Regards
Trevor
