Raw live view of Sun (Chromosphere, Hydrogen light), Lunt 60THa, Skyris 236M camera 18 May 2021 pt4

I did some Solar imaging on the afternoon of 18th May 2021 from NW England which shows the Chromosphere of the Sun, our "local" Star. I used a Celestron / The Imaging Source brand Skyris 236M Monochrome (black and white) camera along with the free image capture software Sharpcap 3.2.6480.0 on a Lunt 60THa Tilt tuned Solar telescope, this time with 2x GSO / Revelation brand Barlow lens used just before the camera, the camera was used at it’s native resolution of 1,920 x 1,200 pixels, captured over USB 3.0 with an exposure of about 60 milliseconds, capturing at about 16 Frames per second (but the video plays back at only 30 FPS here), resulting in around 1.9GB of raw data, and capturing around 900 Frames of video images. This is the raw video from the camera with no processing, just so you can see what it looks like.
This is my “First Light” for this camera with any telescope, and is my first high resolution Solar imaging with any camera, a dear friend of mine in Japan helped me to obtain the camera which was being sold off pretty cheaply by a Japanese firm, it seems that this camera was not terribly commercially successful but it works very well in Sharpcap and also in Firecapture 2.6.08 x64 . I was initially attracted to this camera when I saw the images that it could produce with small Lunt Solar scopes on the Charlie Bates Solar Astronomy Project forum run by Stephen Ramsden. Normally I am not an “imaging” kind of guy and mostly use eyepieces with my Solar and other scopes but this was kind of fun and new for me. The mount used to hold the scope was a Celestron CG5 ASGT. It is a shame that I currently cannot bring the same camera to focus on my smaller Lunt 50 with Double Stack, I'm working on ways to do so.
I have Newton rings affecting the image, that I don't get without the Barlow. How to I get rid of them? Camera tilt?
This is part 4.
