I've definitely seen the wormy noise you referred to. Thanks for the input  |
My A7r2 works quite well but I hope to see future improvements in this area.
I suspect one way to beat the star eater algorithim is to make sure your exposures are long enough so the signal isn't mistaken for a hot pixel.
One thing to consider is the thickness of the stack.
I've read about a Kolari mod which is a thin stack (glass on top of sensor). That may be more for the A7. But worth finding out about.
Greg.
