Today I took a few shots of a large Solar Prominence through my wife's Hydrogen Alpha Solar Telescope (a 'double stacked' Coronado Solarmax 60mm).

I'm more experienced in processing deep space images, so these looks a little rough. The camera I use for bright targets is monochrome so the colour is 'false' (but we all know the sun is yellow/orange right ?)

Well. now I know why I kept dropping calls all day on my cell phone.

That's pretty awesome. Looks like the sun threw a tizzy.

awesome work there

That was awesome Paul! ...so the Sun does shine in Ohio - weird, never did that when I was there.

btw, there is alot of Solar activity going on now, correct?

Wow, that is truly stunning to look at Paul. Great work!

Again, amazing work, Paul. Really impressive stuff!

wow... correct me if I'm wrong, but very roughly, that protuberans at the top of the photo is around 150.000 kilometers long??? Or, around 40% of the distance of the Earth to the moon.

How did you arrive at that number? Did you see it published online somewhere?

Approximately that long, yeah; you can get a very rough estimate with a ruler, Paul's picture and wikipedia. If you measure off the sun's (rough) diameter at about 5.75 inches (on my 13.1" screen), and get the real diameter from wikipedia as being 1,392,000 km, then measure the ejecta at (very roughly and conservatively) half an inch on my screen, then scaling it up gets around 120,000km, so that's the kind of order of magnitude we're looking at. Pretty damned big, if you consider that the Earth is only 5400km in diameter.

Mind you though, some cars have driven that distance, and then some...
