Does dimming of Betelgeuse reveal nebula

Recommended Posts

This may be an artifact, but I took this shot of the Orion Constellation from the Canary Islands and it showed a small nebula around Beteleguse. Do you think this is real? The shot was taken with a dual band filter which brings out the Ha.  I initially assumed it was a camera artifact, but I took more shots with different camera positions and it was still there.  There are some on-line articles about such a nebula. My first reaction was to edit it out, but I think it might be real and only visible because Beteleguse has dimmed by over 50%.  What do you think?

Definitely an artifact. It would be large and very noticeable if real , no matter how much Betelgeuse has dimmed.

It COULD of course be real but with all the attention BG is garnering I can't believe the community is missing it.

I have seen some hi-res Hubble (I think) images showing a bow shock wave ahead of BG but far too small to be seen in our wimpy scopes.

That article states the FoV of the image with the nebula is 5x5 arc secs... so the nebula itself probably 2.5x2.5 arc secs.  Safe to say that would not be visible in your image.  It also states that the nebula cant be seen in visible wavelengths.

Sorry but have to agree that it's an artifact in your image!

      Hi! I've recently acquired a new Astromodified Canon rebel XT and I've tried to take pictures of nebulas using it but I've noticed that there are these weird black artifacts that keep appearing in my images. Would like to know if anyone has experienced this before? Or are these dirt/dust specs on the camera, filter, and telescope glass? I've attached some of my edited and raw pictures for your reference. The black artifacts can already be seen in the raw image of the horsehead nebula and after stacking I think it got amplified. Anyway, advance thanks and I hope everyone's doing well.

      I've been processing this image for quite a long now.
      I started acquiring data the last season when I only managed to shoot 3 panels with the Canon 6D through the Esprit 80 for a total of ~7h.
      This season I restarted and I added more data and covered a wider area. So a mix of portrait and landscape panels were planned and shot with the same scope and camera. Now every pixel represents at least 3-4h of integration, some have more.
      All the above were shot from Bortle 2-3 sites where I traveled sometimes even for an hour of exposure.
      To the RGB data I added 17.5h of Ha, same story with the panels. Some were oriented N-S, others E-W. These were shot with the SW 72ED and the ASI1600 from home and Bortle ~7.
      Then I figured out I still had time and I planned and shot 9 more panels of luminance with the 72ED and ASI1600, each consisting of 1h of exposure.
      I combined all of these into an image, processed it and for the Orion nebula and Running Man nebula I also blended some data I shot last season with the 130PDS and ASI1600 from home.
      Below it's my first final version of all data combined. You can watch it in full resolution on astrobin: https://www.astrobin.com/full/jni0w8/ or Flickr: https://flic.kr/p/2iBGUXq
