I measured this high amplitude del Scu star during February and March with my 500mm refractor and Canon 450D. 
I calculated the two periods (first and second overtone of the radial pulsation) using VSTAR in good agreement with published literature data.

P1 = 0.17835 (0.17836, Cox. et al)
P2 = 0.14279 (0.14280)

Analysis of the amplitudes shows a strong variation with a mean of 0.501 and a standard deviation of 0.128

VZ Cnc

Are you observing VZ Cnc this year?  I was wondering whether its dual pulsation modes were remaining constant in period and amplitude.
