- Аннотация: Results of surface photometry are given for the inner part (D = 100'' almost-equal-to 24 kpc) of the barred spiral galaxy NGC 151, obtained by an image-tube device of the 2-m telescope at the Semaha Observatory (Azerbaijan). Surface brightness of the inner dick of the galaxy and its of bar falls down exponentially with linear length-scales alpha-1 = 1,32 kpc and 3,3 kpc respectively. A colour gradient DELTA(U - B) and DELTA(B - V) along the radius of the galaxy is found: from the <<red>> circumnuclear disk down to the <<blue>> inner ring. Positions of UBV-colours of the bar regions on the two-colour diagram differ noticeably from the normal colour sequence which may be explained by a suggection that new-born stars, while moving along their orbits, go away from the bar.
