Abstract
ABSTRACT It is shown that the effects of crowding on images of Kepler's supernova remnant, that were obtained with the 3.6-m CFHT, can be greatly reduced by digitally subtracting a scaled continuum image from a narrow-band H-alpha + forbidden N II image. Attention is drawn to a narrow emission filament that extends for 27 arcsec along the western edge of the optical remnant.
