M42 And the running man HaRGB

Recommended Posts

I keep "upgrading" my older pics and it actually turns out better then i thought it would... :)

I first captured Orion RGB on the 7.3.2014 with the moon really close by (18x150sec@ISO200).
Later that year i added the running man with RGB data from 26.12.2014 (11x120sec@ISO800), and the pic instantly looked "more complete".

Then here a couple of weeks ago i was able to gather 20 min of Ha data (10x120sec@ISO3200]. Not nearly enough with my unmodded 550D, but helped a bit still.
It's my first attempt in HaRGB, so i'm quite pleased with. :)

Edit: First is HaRGB, 2nd is the old RGB.

Very nice images, I prefer the first to the second. I think they could be improved by making the background a touch less dark. They have a slightly "clipped" look about them.

Thanks. :)

 

The first is the HaRGB, the 2nd is the standard RGB. Forgot to mention, sorry.

      The Orion Nebula imaged in RGB through a Celestron 8" SCT at F10 (2032mm FL) using a full spectrum modded and cooled Canon 40D. Tracked using a Celestron CGEM mount. Total exposure time was 1 hour and 24 minutes.

      Hello All,
      I was wondering whether it's possible to image a DSO and capture any depth. Every 3D astro image online is faked so at the start of the year, I decided to image M42 six months apart.
      Back in March I posted a image of M42 imaged at f10, 2032mm FL through my 8SE on 28th February 2019. Than on 3rd September (setup and captured 15 second subs on 1 September) I captured M42 at the same focal length, same orientation and very similar subs for a total exposure of 1 hr 24 minutes. This was almost to the day exactly 6 months between the two images, so the earth was 300 million km away from the original position on the other side of the sun, furthest I could hope for imaging a 3D stereo pair.
      First attached is the image from September...

       
      I color matched the above image with the image from February, aligned them and below is the end result....

      As you can see there is no detectable 3D effect... There was a 3Dish effect but this was most likely due to the differences in processing of the two stacks and when I SCALE and rotate the two images to align them, and hence no 3D effect.
      Of course the stars and nebula are certainly not on a flat plain so I believe that the reason for the lack of any discernable depth is simply due to the distance of M42 resulting in  a very small angular shift in the stars, so small in fact, that it’s beyond the sensitivity of my 8” SCT, camera pixel resolution and tracking accuracy of the CGEM.
      Calculation of the expected motion of any parallax shift when the Orion Nebula is 1344 lightyears away and the distance of Earth being 149,600,000km from the Sun:
      1344LY = 1.2715e+16km
      Θ° = Tan-1(149.6e+6/1.2715e+16)
      Parallax Shift Θ” = 2 x 3600 x Θ
      Parallax Shift Θ” = 0.0048536712567150
      An angular motion of 0.005” was not picked up by my system that tracks with an average accuracy of about 1” RMS, with a camera sensor that has a resolution of 1.16”/pixel at 2032mm focal length with a 8” SCT. Even if I could get consistent tracking at the best accuracy that I have ever seen with my gear, 0.38” RMS, this is still well above 0.005” and well beyond the 40D sensor pixel resolution, and all this is without considering atmospheric distortion, obviously my setup is not even close to sensitive enough.
      This was a good project but unfortunately the distances of objects in the universe are too great, even objects classed as in our celestial “backyard”. If I didn’t try this experiment than I would be always wondering and curiosity would most likely make me try it eventually.
