What telescope do I need to split HIP 109745?

Splitting HIP 109745 requires an aperture of roughly 320 mm or larger — the components are separated by about 1.5″ at magnitudes near 5.5. The companion is about 3.9 magnitudes fainter, so glare from the primary — not separation — sets the minimum aperture. Larger apertures and steady seeing help resolve the pair cleanly.
