7D, No purposeful cropping.
Used PSE to straighten the curves a bit but could not get rid of them completely and some parts got "Cropped" by virtue of the straightening. The corners only as you can see.
Here is the SOC from the Raw.

Thanks, compared to my first image above (7D II) it did look as if you'd straightened the curved lines a bit. Again, great shot.
I also have the Rokinon/Samyang 14 f/2.8 and 24 f/1.4, both full manual. They're my go to lenses for astrophotography. Use them on my R5 and 5D IV..... 7D II as a last resort, due to the inherent noise.

Nikon used to have a rectilinear lens for film cameras. See if you can find a used one.

I have the Nikon 10.5 mm fisheye. I used Photoshop to take out the distortion one time and was surprised at how good the over all quality of the image was. Of course the pixel density in some sections of the picture are very different from other areas so you need to be aware of that. This was done using Photoshop 6. Don't know if that feature is still around in the later versions.

Do you recall just where in Photoshop 6 you found that feature? And I assume you mean PSCS6?

I will have to check. PS 6 is installed on an old Win 7 computer that is little used these days. I keep it running for the many programs that I might use that are not supported by Win 10. This has become a very irritating issue with me. I keep hoping that someday a third computer operating system will be born that will support these older programs. I have no experience with Linux but I'm pretty sure it won't run Windows software. Maybe someone can correct me on this.

Squeezing an extremely wide view onto a sensor is always going to create distortion. In general, a fisheye lens bends straight lines,but preserves angles. A rectilinear wide angle lens preserves straight lines (at least mostly), but distorts angles.
Extreme wide angle lenses (those shorter than 21-24mm FFE, or so) tend to be special purpose lenses. They need a good deal of understanding of their characteristics, capabilities, and limitations for most effective use, and very often find themselves sitting on the shelf or resold, usually at a loss into an oversaturated market.

I'm still in my 'learning curve', but at the suggestion of fellow members here, I purchased the Fisheye-Hemi 2 software. I'm rather impressed. I can confidently tell you that the 8mm lens truly does capture a much wider image than my 17mm Canon lens. Without using the Fisheye-Hemi 2 software, I've found that I can crop only the center (16x9) and result in a nearly perfect image, yet much wider than my 17mm. With the Fisheye-Hemi 2, can can get an even wider image, looking quite good.
I'm still going to look into my PSCS5, which I never use anymore since I've totally switched over to Affinity Photo, but Boney suggested that PSCS6 might have a correction filter. But for all those of us, wishing to explore an 8mm super wide angle, the Fisheye-Hemi software is worth looking into.

PSE 2021 has the feature so I would guess PS today has it.

How is that featured titled? Is it a filter?

I'm curious to ask, do any of you own an 8mm fisheye lens? And if so, how do you use it?
