I have been doing solar imaging for a number of years. The Newton ring issue is real and a pain, and is unpredictable with many theories re: its genesis, etc. I have purchased 5-6 video imaging cameras, and whether they are expensive or cheap it doesn't seem to matter.

I have a TeleVue Pronto for full disc imaging and I have never had Newton's rings with ANY of the cameras.

However, my TV 102 has it with EVERY camera I have tried.

These rings are a nuisance in and of themselves just by the virtue of being there. I hate seeing them visually, and yes you can process them gone, but it is less than aesthetically appealing.

My answer has been solved with the T2 tilter for my ASI 120mm. It works like a charm, and at ~ $38 USA is well worth it for me.

Thus changing the imaging angle against the plane of the telescope lens has fixed the issue. And yes, I am smiling much for that.

Thank you ZWO [this is not a paid ad] for offering this product.

There is a very good video on YouTube by Wise Imaging that lasts for just over 51minutes.

Hello there the video shows a picture of part of the Sun and is by Wise Imaging, I do not know how to add a link as I am using an Apple iPad. So the best I can do is suggest you go onto YouTube site and search for Wise Imaging, I think there is only one video by them/ him !!! The video goes from start to finish explaining data acquisition to processing.
