Af(rho) parameter according the CARA-approach

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

Comet C/2014 Q2 (LOVEJOY) -   10 apr. 2015

Image comet C/2014 Q2 (LOVEJOY) taken from  iTelescope.net New-Mexico with a 0.51 f/4.5 telescope and FLI PL11001M camera. 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: 5x60 sec with clear filter in 1x1 binning, and 1 x I + 1 x R with exp. Time of 60 sec each in 1x1 Binning
