Some people just have an eye for producing great images, but I'm not one of them
. Every so often I try to improve my images by precessing a bit differently trying to get more detail, etc but I'm not always sure whether its a step forward.
The tricky bit with these solar images is trying to bring out the prominences and the surface detail without losing too much detail near the limb. At the moment I'm favouring capturing the prominences and the surface detail in the one shot rather than doing a HDR or stacking/masking process, so its all in the curves adjustment
The other thing I did in this repro was to pick different alignment points and stack fewer frames (50 instead of 130 in the 1st on) just trying to get it sharper.
