The usual tradeoffs, low stray light, high spectral purity and tunability but lower resolution.

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.
