There's usually something to see.

The usual tradeoffs, low stray light, high spectral purity and tunability but lower resolution.
Observing the Sun with complex optical systems since 1966, and still haven't burned, melted or damaged anything.
Not blind yet, either!
Light pollution? I only observe the Sun, magnitude -26.74. Pollute that!

These are excellent Joe. What bandwidth are you running at here?

Once again you demonstrate the excellent capabilities of the SHG system. Well done!

Thanks, guys. I don't get as much time in on this as I used to, another unrelated project is taking up a lot of my time, but for a good cause. The bandwidth is 0.3 Angstroms. Seeing was good yesterday, 2-3 arcsec, and little haze or smoke.
