G'day all,

 

I shoot with a Canon 600D/T3i. Some time ago, I did an experiment on the sun to see what worked better to capture surface detail: a JPEGs, a RAWs, or a stack of LiveView frames. For such a bright, low-contrast target, I found that a single RAW frame did better than 3500 LiveView frames.

I always assumed this was true for the moon as well, but last year I got some decent quality LiveView stacks on it up well past the diffraction limit of my 7-in Mak (~f/50). I was wondering about this again a few nights ago as I was trying to get decent full-disk images with my 200mm lens. So I captured a set of both for comparison. I also compared L-RGB with L and RGB from either stack (so 4 combinations):

Here's an animated toggle among the four:

At least for this setup, the RAW stack is far superior to the LiveView.

 

Cheers,

 

BQ
