AR 2158 minimum gain setting

[Pete Presland]

tried a slightly different approach to the capture of the surface detail, to see if i could get more contrast and detail.

normal settings gain 750, exp 1/92, gamma 30

new settings gain 260(min), exp 1/92, gamma 40

the usual set up Coronado PST/DMK21au618 2000 frames stacked around 500. i think it has slightly more contrast, but not a huge amount. looked more when i was capturing to be honest.

Great images but gotta say i prefer the first one.

I know the joy of seeing the sun. Oops, I should write, KNEW the joy, ... Etc. :-)

Nice images. Thanks, as ever.

More realistic?

Think its the more even illumination in the first one. How far apart were they taken?

5 minutes, looking at them again i agree. the closer to the limb the darker it is, particularly the bottom corner  almost nothing left of the limb.

Amazing difference in surface activity in 5 mins.

Absolutely fantastic :) first is definitely better.

I would always stay on minimum gain, the Sun provides plenty of light so why introduce noise. On gamma however, I am not sure what your neutral gamma is but for the DMK41 it is 100, I would never personally go below 85 otherwise you will lose detail, you can add contrast later in Photoshop.

Very nice shots, Pete, always worth experimenting. I slightly prefer 1, but I think 2 makes a nice change.
