Greetings! I have found that when shooting with some clouds and the AR152 I get some type of bubble artifact in the upper right corner. It is consistent in it’s location and is always clearer than the rest of the image. I have been able to get rid of it but at the expense of other important nebulosity. It is still evident in some of my posted images. Anybody experienced this and did you find a way to deal with it? Thanks in advance.
Clear skies!
