Starting to get some good conditions at last with planets.
This morning settled down well after a disappointing blurry Jupiter.
Using the residual CA in the optical train (Amici & Binovu)
I was just able to cancel the atmospheric dispersion by placing Saturn in the south part of the field;
similar to using the old trick with a Ramsden eyepiece.
Also the apodizer was suited by the type of seeing that developed.
Fog came in pretty soon after I got Mars!
