Remarks: |
Abell 35 is a very dim PN with a visual size nearly identical to the Helix Nebula. Obviously it is much older than the Helix-Nebula, which is revealed by its not well defined shape. Four minor plantes are visible in the image (the position specification is relative to the brightest star in the image: At 13:00 :
2000 WL11. Image processed with CCDSharp and DDP. In addition to L and B two narrow band filters (Ha for red and OIII for green and together with B for blue) were used. With this filter combination the colors of the PN are displayed nearly in "true color", but this is not possible for the stars and galaxies in the image. Their continuum radiation can only be displayed insufficiently when narrow band filters are used. |

Bemerkungen: |
Bei Abell 35 handelt es sich um einen sehr schwachen PN, der etwa die selbe scheinbare Größe am Himmel hat, wie der Helix-Nebel. Er ist aber offensichtlich deutlich älter als dieser, was sich durch seine nicht sehr wohl definierte Form verrät. Interessant sind die vier durchs Bild ziehenden Kleinplaneten (Positionsangabe relativ zum hellsten Stern des Bildes):
Bei 13:00 : 2000 WL11. |
