We are proposing to use the 0.9 meter telescope to obtain H(alpha) images for a complete sample of bright, nearby, early-type (Sa-Sab) spiral galaxies in the northern hemisphere. The images, when combined with those we have already obtained from the southern hemisphere, will provide a significant new all sky perspective on the star forming capabilities of early-type spiral galaxies. Our preliminary results have revealed early-type spirals to be a heterogenous class of objects. Some have nuclear starbursts that are hidden from direct view by the large stellar bulges. Others have giant H-II regions in their disks that are so large and luminous that they rival even the largest H-II regions seen in late-type spirals. These surprising and unexpected results have prompted us to continue our imaging program from the northern hemisphere. Our ultimate goal is to image an all sky sample of 57 objects that constitute the largest and most complete sample of nearby early-type spirals. Imaging the largest complete sample will circumvent incompleteness corrections and minimize statistical errors when quantifying the diversity of star forming activity seen in nearby early-type spiral galaxies. We have already imaged early-type spirals in the southern hemipshere. The current proposal is to finish off the northern hemisphere sample.
