The tilter is at max and still NR....
I'll try different orientions of the camera to the etalon tilt axis.
They seem to be there with all my barlows (PM, Baader, AE and the ES)

Hi Ken,
Ok I see the rings now in your prom images but I didn't notice until you mentioned. So didn't/doesn't detract from the images for me.
I am coming from little experience here but am sure I will be going there so have been reading about the dreaded NR and found this article. You have probably seen it and you have already tried the tilter but seems some other thoughts in there also.
Also found the attached camera guide for Solar Scopes - seems some are more NR affected than others? Why is this? Says my ZWO120MM should be cursed by NR but I either don't know what I am missing or lucky.
