I think of the Witch Head as being located in Orion, but it is in fact in Eridanus. Since it is thought to be illuminated in large part by Rigel, it is easy to get that wrong. According to Wikipedia it is about 900 light years away. Rigel is similar in distance (according to Wikipedia about 860 +- 80 light years).
It is rather dim and not prominent at all in the individual subs.
