These two images were taken from the same imaging run, 60 of 120 images stacked, 1/1000th @ ISO100. The RAW files were processed with PIPP, but I couldn’t get Registax to process the TIFF files produced by PIPP from the JPEGs so I used the camera JPEG files directly. Both stacked in Registax v6 and finished off in Photoshop. I don’t think I need to hide which is which. It’s blindingly obvious…
First, the image from the RAW files:
and from the JPEGs:
And crops of the sunspots from the full size images:
I might try again, converting the JPEG to monochrome first, but I don’t think there’s any real comparison. The reduction in size of the JPEG in the full solar image clearly does it a lot of favours.
