Observations of comet Kohoutek (1973f)The coma region Comet Kohoutek (1973f) was observed with a 40-mm proximity focused image intensifier tube and filters to isolate principal emissions. The low brightness of the comet limited the results, but it was possible to compare the intensity profiles of C2 and continuum in the coma. It appears that Comet Kohoutek was a typical comet in that it did not exhibit unusual coma structure similar to that of Comet Bennet. Photographs taken with the 42 cm Schmidt showed typical type 1, type, 2 and antitail morphology, with increased type 2 activity after perihelion passage. A technique for eliminating the type 2 (dust) component of the tail is given by means of photographic subtraction of blue and red sensitive layers of a color photograph.
