What telescope do I need to split HIP 72573?

Splitting HIP 72573 requires an aperture of roughly 560 mm or larger — the components are separated by about 1.9″ at magnitudes near 5.6. The companion is about 5.9 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
