New optical filamentary structures in Pegasus
Panayotis Boumis, Fotis Mavromatakis, Euthimios V. Paleologou +1
Deep Halpha+[N II] CCD images have been obtained in the area of the Pegasus Constellation. The resulting mosaic covers an extent of ~7.5 degr x ~8.5 degr and filamentary and diffus…
Deep optical observations of G 65.3+5.7
Fotis Mavromatakis, Panayotis Boumis, John Papamastorakis +1
We present the first CCD mosaic of the supernova remnant G 65.3+5.7 in the optical emission lines of [O II] and [O III]. The new images reveal several diffuse and filamentary struc…
Optical observations of the supernova remnant G 69.4+1.2
Fotis Mavromatakis, Panayotis Boumis, Euthimios V. Paleologou
We performed deep optical observations of the area of the new supernova remnant G 69.4+1.2 in the emission lines of [O III], Halpha+[N II] and [S II]. The low ionization images rev…
