 Hello, 

 

I've realised that my flats, when debayered and white balanced, have uneven color.. 

bottom seems redish 

 

using qhy8L OSC with Optolong L-pro  filter and Hotech SCA field flattener (filter in front of flattener) 

 

 

Anyone knows what can it be?  I thought maybe tilt, but tried to adjust and even though still there's that

weird coloring..

 

Thank you 

 

Carles.
