During the spring of 1957 a series of photos of the known Hubble comet-like variable nebula NGC2261 was taken with 70-cm meniscus telescope of the Abastnmani observatory. The photos were obtained in violet and yellow light and through a polaroid. The most reliable negatives were treated photometrically. 4 crosssections of the NGC2261 were made with a self-recording microphotometer in the East-West direction at different distances from the top of the nebula. Following conclusions were made: 1.The nebula is characterized by a complicated structure of luminous matter; the luminosity in yellow light being more amorphous than in violet. 2.A violet light is being observed in the middle part of the axial region of this Comet-like nebula. 3.The polarization in NGC2261 is mainly radial with respect to the head of the nebula. Its average value is equal to 19%. The maximum rate of polarization (sometimes it is equal to 60%) is observed in the east stream of the nebula. This fact is illustrated by the fig. 4. 4.There is no correlation between colour and polarization of the nebula. September, 1958.
