Abstract
I have obtained narrow-band interference filter photographs in the light of Hα, [S II] and [0 III] of the SNRs G126.2+1.6 and G206.9+2.3 whose optical emission has been recently discovered, as well as that of the SNR CTB 13 which has been identified with some filaments on the PSS prints. The first two SNRs show high [S II]/Hα and [0 III]/Hα line-ratios. The photograph of CTB 13 obtained in [0 III] shows a spur coincident with the filaments visible on the PSS. A discussion of these individual SRNs is also given.
