Looking at the light curve

Looking at the light curve Stewart, there is not much difference. In any case, the objective of the project is to measure the time and duration of each outburst, rather than its precise mag. Thanks for your observation. If you are getting decent signal to noise ratio then stick with the V filter -after all, you are using a decent aperture scope. But no filter allows better SNR, so is often preferable with small telescopes.
