Thanks guys, I appreciate all the comments and feedback.
My most enjoyable challenge was trying to manage the huge brightness range on the Aristarchus plateau and the only way I could manage this was to taken 2 AVI’s exposed for the darks in one and the light tones in the 2nd one and then blend the final 2 images in CS6 to show the tonal range without blocked up blacks and blown out whites.
I found SharpCap very stable and tried FireCapture but it (FC) froze on me so I bailed out and stuck with SC.
Cheers
Dennis
