Description
CCD images of the Seyfert type 1 galaxy NGC 4151 were obtained under excellent seeing conditions (FWHM ≅ 0.7 arcsec). The images were taken through broad-band V, R and I, and narrow-band Hα filters. Analysis of the data shows a complex structure in a region of about 4 arcsec around the nucleus. We found two main systems: (i) an elongated structure present in V, R and narrow Hα at PA ≅ 60o, extended over ≅ 4 arcsec, and (ii) a nuclear 'bar' of ≅ 1-arcsec length, seen only on the R frame, at PA 150o.
