The Lambda Orionis Star Forming region contains highly interesting field of dust and nebulas such as B 36, B35 and LDN 1602. This FOV is a small part of the whole star forming region centered near Betelgeuse. The dieying star. Recent years Herschel Space Observatory took images of the interaction between stellar winds and the interstellar medium (ISM) how creates complex bow shocks. On the left of the bows a straight bar can be observed, there is no clear explaining about appearance of structures as the straight border.
I think maybe straight wall can be recorded by amateurs. I think I get same structure at same location relative to Betelgeuse’s motion.
All data are following above link.
Thanks for looking
