WHITE
LIGHT:
Lets
start with the full disk, we can see only one major sunspot:

Now
we insert the 2.5x barlow and pull the 4 inch stop off to make
it a full six inches. The granulation is visible as a nice patterning
in the background.

Here
is another prime focus view, with the six inch using the Methane
band filter deep into the IR. Contrast is much lower and the
granlation nearly dissapears:

Now
for some Calcium K shots. Calcium K is in the near UV. This is
with the six inch stopped to four inches, and a 1.5x barlow in
front of the filter elements. This makes it near f/15 and ideal
for detailed close ups in calcium light. Here is the larger sunspot
seen this way:

The
other smaller sunspot was un interesting in white light. But
in Cak, there is much to see!

And
finally a shot of the planet Mercury, a small 8 arc secnds in
size, but a tiny crescent. This is at prime focus with bad seeing
and in the IR.
