Hi everyone,

I hope someone can help me with a processing problem I am currently having.

I'm imaging Saturn with a DMK21 camera, 3x barlow and RGB filters. When I do a RGB combine in Astra image, the red and green channels align correctly but the blue is always out. If I align the blue channel on the disk of Saturn, then on the left side on the rings the blue will be slightly out below the ring and on the right side it will be slightly out above the ring. The RGB channels were all then with in 5mins. Does anyone know why this is happening?

I've attached a screen dump, you can see the blue Channel is out on the each side of the rings but in opposite directions

Thanks in advance
