Jup August 5th in good to very good seeing

Hi All,
Well what a night, early on the sky was covered with light cloud although I could still see Jupiter and the occasional bright star through it.
I had contact Anthony the previous night regarding a processing problem that has been dogging me with my Jupiter images, a ring inside the limb. We had come up with the probable solution, the default gamma setting in IC Capture and I wanted to capture some data to test the solution. Lester had also suggested this may be the problem in a reply to the images that I posted yesterday.
It was quite strange really, the changing density of the cloud played havoc with my histogram but the detail such as the GRS seemed very well defined. A quick and extremely heavy handed process of an avi could not produce the ring artefact so I just filled in time monitoring my Peltier cooler for later in the night when the Bird Strike would appear.
At 11pm CST it was as if a switch had been thrown, the cloud disappeared and the seeing was very good. The image was very steady and the live feed to my laptop looked almost like a processed image, in fact I think I have processed images on some nights that were not as good as what I was seeing from the live feed.
The material from the impact that had previously wrapped around a light coloured oval is still discernable but much dimmer than on August 3rd.
I have posted 3 R channel images and 2 RGB’s. The first of the RGB’s is the best image I have taken for this apparition. I have also posted a 200% crop of the impact region taken from my best RGB. I have also attached a very high res R channel animation of the Bird Strike.
Thanks again for your time Anthony and also Lester for your suggestion.
