Af(rho) parameter according the CARA-approach

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

Comet C/2014 Q2 (LOVEJOY) -   23 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 7 images of 60 sec with Luminance filter. Each in 2x2 binning The images with the photometric filter R,I are in particular for obtaining the Af(rho) parameter according the CARA approach.

Imaging session: 1x60 sec with clear filter in 1x1 binning, and 1 x I + 1 x R with exp. Time of 60 sec each in 2x2 Binning
