Does dimming of Betelgeuse reveal nebula

Recommended Posts

get.jpg?insecure

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'm relatively new to the whole telescope thing but have done my research and was fixed on getting the Orion skyquest XT8i or XT10i. By spending that much money, I didn't like the idea of purchasing it online from their website without seeing it in person (and not having the reassurance of being able to take it back) and looked for stores in the UK that would supply them. After plenty of research, it seems like they don't exist anymore and they are only in the US? Is this right or could anyone help me?
      (I've looked at the Sky-watcher 250PX/200PX flextube skyscan goto but it is significantly heavier and the noise of the goto mechanism sounds like a table saw so that's put me off of it...)
      Any help would be much appreciated,
      Thanks

      Friends, I am back with a tutorial video on how to modify your Sky Watcher HEQ5-PRO mount or its American twin, the Orion Sirius EQ-G into a belt driven mount.
      The benefits of converting to a belt drive is that you don't have to worry about Backlash. The procedure took me about an hour to complete.

      Messier 57 is is just coming into a position for a decent look around 11 30 pm. IT is a colourful object and I thought it would give me a good target with which to practice my colour developing in PS/Lightroom. I have read so much about how to produce a LRGB image from the four stacked/calibrated luminance, red, blue and green images,  a lot seems contradicatory and some, when followed, gave me colour yes, but not as we know it. I am sure a fair chunk must be put down to me. Anyway, I now have a work flow which gives me colour, sometimes resembling what other people have obtained. Progess of sorts.
      This images is based on 114s subs at gain 139, offset 21.
      L 39, R 20, G 20, B 19
      Calibrated  and stacked in DSS (flats, dark flats and darks)
      Messier 57 Ring Nebula in Lyra
       

      NASA: M57, or the Ring Nebula, is a planetary nebula, the glowing remains of a sun-like star. The tiny white dot in the centre of the nebula is the star’s hot core, called a white dwarf. M57 is about 2,000 light-years away in the constellation Lyra, and is best observed during August. Discovered by the French astronomer Antoine Darquier de Pellepoix in 1779, the Ring Nebula has an apparent magnitude of 8.8 and can be spotted with moderately sized telescopes.
      Equipment: Celestron 9.25 XLT at F10,  Skywatcher EQ6 Pro GEM, ZWO 1600MM Pro, ZWO EFW with ZWO LRGB filters, QHY5IIC guide camera on Skywatcher 9 x 50 finderscope, Celestron Focus Motor
      Software: Ascom 6, Eqmod, Cartes du Ciel, AstroPhotography Tool, PHD2

      Since I am very new to this, I struggle a lot. Especially when observing planets and also recently deep sky objects. My telescope is an amateur telescope and its almost 11 years old (The telescope was re used a year ago). During summer of last year I took photos of Saturn,Jupiter and a month ago took photos of Venus and Mars. About 2 days ago I stumbled upon a new thing in the sky, (Unfortunately, I didn't take a picture). It definitely was in the Orion constellation  as I had observed Betelgeuse and the 3 stars that were close to each other. After a couple of minutes later I saw 2 stars next to each other and another two which were on top of the other star, surrounding these set of stars were a blue-ish and grey-ish colour at the same time. I had done some research and many people told me it was the trapezium cluster found in Orion. I honestly don't know. Any ideas? Thanks.
