Hi all,
Here are a couple of addiitonal CaK/H-alpha comparisons.
Two full disks with proms:

Side by side comparsion of AR10956:

Wonderful info! The contrasts are so striking that I
hardly know what to make of them.

Good to see you pair back at taking images without any background
context,that thumbsucking exercise for people who think magnification
is 'astronomy' A childish pursuit in the hands of astrologers it will
be a complimentary addition to the astronomical discipline once the
original astronomical insights shine through the dross of the current
dark ages of astronomy.
"When I was a child, I used to talk as a child, think as a child,
reason as a child; when I became a man, I put aside childish things. "
Christian vesion of a Hellenistic poem.
Go chase your damn planetary shadows projected to Earth and have
others congratulate you for doing so but considering that no
astronomer ever dared promote such a thing should certainly give
genuine people an inkling that something has gone badly wrong.

How did you get such great pics with only 40mm of aperture?

The images are of an overview nature only. If you were to compare the
output of the PST with a larger solar instrument for larger image
scales you'd start to see it's shortcomings. One of the biggest issues
in getting crisp overview shots of the Sun IMO is spending a lot of
time getting the focus right.
However, apart from this, there's no magic here.

Beautiful work Pete ... as usual!
Today I received my Daystar 130mm ERF and I hope to be up and running
shortly in relation to the h-alpha sun.

Excellent. I've been following that ERF around the globe for quite a
while now ;-)

It has found a PERMANENT home. I am quite certain about this. ;-)
It is now time to pursue the PST mod which I will combine with the
Daystar ERF ... and with the AP160 in-between. On the basis of other
work I have seen (from Belgium), there should be some really "sizzling"
results.
Anthony.
