Context :

Aims : This paper is a continuation of an ongoing study of the evolutionary processes affecting cluster galaxies .

Methods : Both CCD R band and H \alpha narrow-band imaging was used to determine photometric parameters ( m _ { r } , r _ { 24 } , H \alpha flux , and equivalent width ) and derive star formation rates for 227 CGCG galaxies in 8 low-redshift clusters .
The galaxy sample is a subset of CGCG galaxies in an objective prism survey ( OPS ) of cluster galaxies for H \alpha emission .

Results : It is found that detection of emission-line galaxies in the OPS is 85 % , 70 % , and 50 % complete at the mean surface brightness values of 1.25 \times 10 ^ { -19 } , 5.19 \times 10 ^ { -20 } , and 1.76 \times 10 ^ { -20 } W m ^ { -2 } arcsec ^ { -2 } , respectively , measured within the R band isophote of 24 mag { arcsec } ^ { -2 } for the galaxy .

Conclusions : The CCD data , together with matched data from a recent H \alpha galaxy survey of UGC galaxies within v \leq 3000 km { s } ^ { -1 } , will be used for a comparative study of R band and H \alpha surface photometry between cluster and field spirals .
