      Description

      Hi everybody,

      Abell 33 is a planetary nebula located 2700 light years away in the constellation of Hydra. It lies just behind the star HD 83535 which seems to rise.

      This image is a bit "non conventionnal". It is only RGB with no luminance. The Red layer was very sharp (1" to 1,35" fwhm frames). So I took it for the stars. The Blue layer was 1,8". Took it with the G layer for the nebula. The composition is :

      - Stars : R layer
      - Nebula : G+B layers
      - Background and colors : RGB
      We might add some luminance next year.
      Hope you will like this faint nebula. Not very often seen.

      Acquisition from S.Brunier / C2PU. Processing JF Bax.

      Look at the full resolution please. The central star is a bicolor double star
