Hi, I had a 150 f/8 lens that I use for solar imaging. I recently watched at the moon, saturn and mars and noticed a yellow dominance, and the usual blue halo on the very bright object. I must say that is quite small even if my lens is the normal acromatic lens, not the R35. Also the resolution is very good, in a very good seeing I could watch at the moon and saturn at 400x. I was looking for a filter or lens that could remove that yellow dominance and blue halo, but usually those fringe killer add more yellow dominance, and i want to avoid it. Anyone had tested and found the right filter to use? Super apo baader filter? a special istar one? Let me know

Most filters designed to remove CA from achros have some sort of yellow component in them. I do not have anything to suggest that removes both yellow and blue. I hope someone else has a solution. I would be interested in knowing the answer.
