- Simultaneous emission line images in the green and red emission lines allowing for temperature diagnostics
- Very High Cadence(3-images per second)
- Simultaneous Polarization images in the continuum and line allowing for density diagnostics, magnetic topology, and 3D structure of CMEs
- Observations close to the limb(better than 1.1 Rsun)
Technological Challenges
- Highly polished primary mirror - Micro roughness of the order of 1Å; an order better than the current technology
- High pointing accuracy - 30 arcsec: requires better than the current technology
- Large format and fast 2D detector arrays
