Betelgeuse, is the dusty straight wall visible for amateurs?

Hi all,

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

I looked a bit for visible light images like this and I don't see any for comparison.  I only find very deep IR images that show it clearly, and UV images that show the shock fairly clearly but not the wall.

 

I can't directly match your image to the Herschel one so I can't tell if the wall exactly lines up with the Herschel image.

 

If it were seen in visible light I'm surprised there aren't easy to find examples on the web - but if the wall is 9' away then it appears roughly to match with your image - but I didn't do any measurements.

 

Can you match and overlay your image on the Herschel one?

There is no much examples about deep sky images around Betelgeuse. I will try to continue looking for it.

 

Roughly aligned but maybe could help:
