ORION Nebula with EOS M handheld - (revisited)

There was a photograph of the Orion Nebula that I had taken with the original EOS M (2012) camera back in January 2017. This was before I replaced the original EOS M camera with the EOS M6.  What's interesting is that I took this picture of Orion handheld... using a red-dot electronic sight to aim it while I held my breath, leaning up against my car door, using it for a brace. I was curious to see if it could be done but I was disappointed in the star trails that occurred.

Orion Nebula - handheld with the EOS M + EF 100-400mmL II lens.
Edited with Photoshop and then (this week) Topaz Labs software to remove the star trails.

I had read that even at 400mm, this lens would offer handheld stabilization at speeds as slow as 1/10 of a second.  But 4 seconds was what I thought might work since the focal length was the equivalent of 640mm with the crop factor.  I don't remember if I cropped this image at all but I don't think I did.

The settings used with the Topaz Labs software for this specific image.

I later realized that these star trails weren't likely from my own movement but were more likely from the movement of the Earth. Earlier this week I came across the image again and thought I'd run it through some Topaz Labs software to see if the Sharpen A.I. could reduce the star movement and if the DeNoise A.I. could remove some of the grain.
.
I'm usually not always impressed with the results from Topaz Labs because it's quite random and selective with the results... but occasionally it surprises me.  I probably won't do this again since I now have a tracking mount to use for longer exposures of the night sky.  I've used it to test the M6 out on Orion with the same lens although I've posted those images previously.  The unedited original image (before editing) is below...

Without the Topaz Labs edit, this is what was captured previously.
