The tripod is cheap and old (read: WOBBLY), and the mount's slow-motion worm-gears are stiff, but it works fine temporarily for low-power Sun-watching. I'll get myself a proper clock-drive mount on a sturdy tripod soon, but in the mean time, the Sun is available for viewing. WOWEE, did I mention it looks great through this little dedicated solar 'scope? This next photo gives you an idea of how the Sun looks through this scope (the photographer used the same instrument); if anything, it looks even more dramatic today, with filaments stretching off into space at least twice as far:

Note the string-like filaments and prominences along the limb of the Sun's globe, the granulation of the surface, and what appear to be "cracks" (magnetic disturbances).
When looking at the Sun, it's useful to get an idea of scale. How big are those "tiny" prominences? How miniscule are those grains of solar-stuff? Here's the Earth 'shopped near a small flare, to lend some perspective:

A feature of this telescope that I thought was just a marketing ploy turns out to be amazing: It's "tunable," in that you can turn a little dial between the front H-a filter and the second H-a filter, and this shifts the spectrum of light passing through to the eyepiece a little toward the red end or a little toward the blue end of the H-a band of light. What this does is alter what's most visible, much the way other Doppler effects work: Toward the blue (I know, it's ALL red, but the less-red end of the light-frequency) end, features moving toward the Earth are more visible; toward the far-red, features moving away from the Earth are more visible. I found that most prominences suddenly LEAPED INTO VIEW about 1/2 to 3/4 of the way tuned, suggesting that most of today's liveliness is taking place on the very edge or slightly toward us. Makes sense, considering we can't see the other side of the Sun's globe... and if we could, it would be the same deal over there, of course!
Here's someone having fun naming prominences (you'll have to follow the link to the original to see the full-size image in order to read the sometimes whimsical names):

As I was watching the Sun, my neighbor Bret stopped by his house while running errands, saw me, and strolled over for a view. Even he was able to see these details - surprising, because getting a good look through a telescope pointed at the Sun requires practice. You need to leave open both eyes while covering the one you're not using and shading the other... and focusing at the same time with your third hand. And keeping the Sun centered in the eyepiece by turning the mount's slow-motion equatorial control with your fourth hand. Wonderful to be able to share my first time!
Okay, now I'm back to work. Finals are pouring in, y'know.
