40 minutes exposure on Fuji Super HG V 400 film.
5" f/5 refractor at prime focus.
Abell 35 is typical of the Abell planetaries. Very large and VERY faint! Although the listed magnitude of Abell 35 is 12.8 (photographic), it is about 0.25 degrees across and very difficult to observe without a large telescope and dark skies. An OIII filter also helps. The only telescope I have managed to observe this planetary with was a 17.5" under very dark skies. Even then, it was extremely faint and only vague patches of nebulosoty could be seen.
In the image above, the location of the nebula is indicated by the circle. Abell 35 surrounds the two stars near the centre of the circle. Only the most vague hint of the nebula is visible.
