New observations of the eclipsing nova V1494 Aql were
analysed to estimate the effect of the optical companion
located 1
4 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
