Based on this image, how much deltaV would it cost me to arrive in low orbit of Sarnus?

On this Δv map, the total to reach low orbit of Sarnus from Kerbin’s surface is ~28,980 m/s (≈ 29 km/s) — that’s the number printed under “Sarnus”.

Useful baselines (same map logic):

*   From low Kerbin orbit (LKO): ~28,980 − 3,400 ≈ 25,580 m/s
*   From Kerbin escape: ~28,980 − (3,400 + 950) ≈ 24,630 m/s

Notes the map is implicitly screaming:

*   That’s vacuum Δv and doesn’t include plane-change Δv.
*   If you aerobrake in Sarnus’s atmosphere (or do clever gravity assists), your required capture Δv can drop a lot compared to the map’s brute-force number.
