The DRAGON recoil separator is located at the ISAC facility at TRIUMF, Vancouver. It is designed to measure radiative alpha and proton capture reactions of astrophysical importance. Over the last years, the DRAGON collaboration has measured several reactions using both radioactive and high-intensity stable beams. For example, the production and destruction of 18F in novae was studied by measuring the 17O(p,g) and 18F(p,g) cross sections at astrophysically relevant energies. Both reactions strongly influence the abundance of 18F in classical novae, which - due to its relatively long lifetime - is a possible target for satellite-based gamma-ray spectroscopy. In addition, the recent measurements of the 16O(a,g) and 26mAl(p,g) reactions will be discussed.
