Afρ parameter according CARA-approach

Afρ [cm] vs core distance [km] - data obtained from Bessel R Filtered ccd-images

Image taken with 0.4-m f/3.8 corrected newton telescope (Orion Optics AG16) on ASA DDM85 equatorial mount and SBIG STL 6303E CCD camera. 9 x 120 sec exposures (unfiltered) are taken and separated stacked on comet and stars
