Mars - 2022-11-24 02:48 UTC - 80% Histogram
This image was captured with an 80% histogram, which has been my usual practice lately. At this exposure level, a portion of the left-most edge of the North Polar Hood (NPH) has been getting clipped in my latest images. I took this image for comparison to image that follows this one, which was captured with a 60% histogram.
The image with the 60% histogram was able to endure more sharpening with less clipping. It is also interesting to compare how the details south of the NPH differ. I am not certain which image I like best.
