Hubble Space Telescope imaging and ground-based spectroscopy of old nova shells – I . FH Ser , V 533 Her , BT Mon , DK Lac , V 476


In this paper we report on the first five out of eleven observations in our programme of Hubble Space Telescope (HST) imaging of old nova shells. We present new WFPC2 images of the shells around FH Ser and V533 Her taken in the F656N (Hα+[N II]) filter.
