Better model-independent theoretical predictions and input to parton distribution functions are vital to improving our understanding of how the nucleon is formed by quarks and gluons. By using a second order extension of the Feynman-Hellmann theorem we examine the nucleon Compton form factor $F_1(\omega,Q^2)$ without the need for calculations of four-point correlators. The calculation is performed for multiple lattice spacings, volumes and a large range of $Q^2$ up to $9 GeV^2$, allowing examination of lattice artefacts and higher twist contributions.
