New observations of the eclipsing nova V1494 Aql were analysed to estimate the effect of the optical companion located 14 to the southwest. R and I-band images (stellar ) taken close to the primary minimum were used to determine relative magnitude differences between the nova and the companion, which were found to be and (in the sense nova minus companion). After correcting R-band time-series observations for the secondary light, the eclipse depth has been found to be almost twice as deep. Before modelling any late eclipsing light curve that is available in the literature, the data must be corrected for the light of the companion.
Key words: stars: novae, cataclysmic variables / stars: individual: V1494 Aql
