  Wide field CCD observations of three, less known, supernova remnants.
Filamentary and diffuse emission is discovered from the supernova remnant
G67.7+1.8. Emission can also be seen in the ROSAT All Sky Survey data which
indicate an extended hard X-ray source. The optical radiation from the
G31.5-0.6 area shows weak sulfur emission and is probably not related to the
remnant. Weak sulfur emission is also observed from W51C or G49.2-0.7. However,
a small patch of emission in the south-east seems to emit strong sulfur
emission. Results from long slit spectra are also presented.
