摘要：

We briefly describe technical aspects and specifications of the new UKST H alpha interference filter, which is probably the largest of its kind available in astronomy. Preliminary exposures show that the filter gives excellent imaging with high overall transmission and uniformity at H alpha wavelengths. This is achieved over a circular area of about 305 mm diameter or about 5.7 degrees (the so called 'clear aperture'). The prospects for the new UKST H alpha survey of the southern Milky Way with this new filter are excellent.
