Helix nebula -planetary nebula
-NGC 7293- |
|
| |
The Helix nebula is situated in Aquarius
at a latitude of -57°. To visual observers,
even to those who use a medium-sized telescope,
the Helix nabula is not particularly impressive.
It is large, with an angular diameter about half
as large the disk of the Moon. However, photographic
techniques reveal its complicated fine structure.
This is particularly true when using a film sensitive
to the red H line; the human eye is insensitive
to faint light of this colour. |
