Hi Dave,
Nice avi.
Just wondering if you have active cooling.
There seems to be be a fair amount of rippling across the image, this may well be due to air currents in the boundary layer of air across the face of your primary mirror.
I suppose when comparing raw avi data the image scale is crucial in the comparison. If the image scale was greater then this ripple would also be magnified.
I would rate the seeing, based on this avi, at about 6, however this topic tends to be very subjective.
I was going to upload a red channel avi from Aug 12th taken in seeing that I rated as good 7 to better than 7. However it is 357 MB so even the IIS FTP site is not really an option. It has a considerably larger image scale and there is no ripple at all, however the image quality does vary slightly.
I have posted the images produced from it on this forum and also an animation of RGB images taken with good seeing.
It really is quite surprising how little processing is required when the data is good. With Jupiter I think the determining factor regarding the seeing, is how well resolved the very small ovals in both polar regions are. In less than good seeing these tiny features are lost.
Regards
Trevor
