Af(rho) parameter according the CARA-approach

Af(rho) versus aperture radius (in km) - I-Bessel filter

Comet C/2014 Q2 (LOVEJOY) -   27 march 2015

Image comet C/2014 Q2 (LOVEJOY) taken from backyard observatory, BRIXIIS Observatory with a 0.4-m f/3.8 telescope and SBIG STL6303 camera with Clear, R-Bessel, I-Bessel and V-Bessel filter. Unfortunately there  was full moon. Image below is an average of stack of 6 images of 45 sec. Ecah in 2x2 binning The images with the photometric filter R,I and V-Bessel are in particular for obtaining the Af(rho) parameter according the CARA approach.

Imaging session: 6x45 sec with clear filter in 2x2 binning, and 2 x I + 2 x R + 2 x V with exp. Time of 60 sec each in 1x1 Binning

Results of the Af(rho) parameter can you find below in this page
