There is some spectacular prominence activity on the sun today. The image above was captured with the PST without the DS filter.
Below is an overexposed, inverted image of another prominence. Connecting loops of plasma twisting in the sun's magnetic field are clearly visible.
The mosiac below was also captured today. It's a little disappointing because I forgot I had tuned the filters for prominences, not surface detail. The disk looks rather featureless and the sunspots are dark, rather than the bright patches they show when the filter is correctly tuned (images below were all taken in DS mode).
The detuned filter did allow me to image sunspots looking similar to the way they look in white light, but with some H-Alpha features, too.
