Something different. Playing around with using Affinity Photo 2 to remove Chromatic Aberration from a test photo (a S5iiX Hi-Res 96MP RAW). I don't have a lot of experience using the app. Its CA removal tool is a one-click operation. I don't know if a high contrast image like this one is easier for apps to remove CA, or if a real-world random photo is more difficult. In any event, in this test it worked really well.

The 1st image is a crop of the original photo's full width (12,000 pixels), scaled-down to 50% (6,000 pixels) so the JPEG wouldn't be too gigantic.

The 2nd image is the same Hi-Res photo, but with CA removed by Affinity Photo 2. It's also scaled-down to 50% (6,000 pixels).

That's amazing for ISO 51200 !!
 
Finally finished going through the Cosmosphere pics... been feeling sluggish and not wanting to dig through the pics to cull/post-process. :(

Good old Odyssey... still the same basic presentation, though they added a fancy frame:

TTArtisan 11mm fisheye

One of the few areas that didn't change at all with the renovation, but I welcomed the chance to capture it with the fisheye.

And the fisheye definitely gave a better view with these pics of the LM engineering model from the last post. (I had a lot of trouble trying to capture a worthwhile interior shot using rectilinear lenses, no matter how wide.)

Another place it helped was the Apollo-Soyuz display, which doesn't have enough room to back off and get a full-width shot with a rectilinear lens.

This is about the best you can do rectilinear:
