If you have photoshop elements or similar you can straighten out the light house easily with the perspective correctional tool.
Hoizon will stay straight.

One thing to look out for with "straighten image" is that, by "tilting" the whole image to pull the lighthouse more upright, your ocean on the other side will also tilt. In my experience, more folks are bothered by bodies of water that look like they are about to slide off to one side than they are by a distant vertical object that is slightly off-kilter.

I am not familiar with Luminar, but look in your menu for "transform"
Then select the entire photo, (Ctrl + A), and drag out the top right corner of the photo.
If "Transform" has a sub-menu, you may have to try which one works best.
Also, the overall shape of the photo will now be distorted (to 3 "straight" sides and one on a slant), so you will have to crop a bit of the right side to get it straight again.

Gimp (free) has a perspective tool that is easy to use. It will do exactly what you want.

I think Perspective Warp in PS would work. Just pull the top right corner out (and up or down if its grabbing the horizon line. Recrop. To avoid or minimize the effect when taking make sure the camera is level in the front to back direction. (All of this is 'I think' - but worth a try)
Yep, that will definitely do the trick.

Are you sure the original was straight?
That was my question. There is a slope landward of the lighthouse.

I don't think the lighthouse is tilted. I think it is a funnel shape and you are seeing the right edge of the funnel is not vertical to the ocean. If you look at the front of the houses below the lighthouse and the lookout at the top of the lighthouse they doen't seem tilted at all.

I used the rotate option under cropping in Affinity.

If you really want to exercise your "straightening" technique.....there is this quaint little town in Italy called Pisa. They're got this tower....

That is exactly why I asked about the original setting.

In Lightroom I use the Vertical Perspective slider to fix such problems. The visual error of the lighthouse not being vertical when the ocean horizon is level (horizontal) is probably caused by a slight tilt of the camera lens upward. This effect should be corrected using the Perspective controls. (Since it's a wideangle lens, it might also sometimes require a little Distortion correction--barrel or pincushion.)

Affinity has a similar control and you can use it on single or dual. In this case, dual works well with the ocean on the left and the lighthouse on the right. You can adjust the lighthouse to vertical and the ocean to level, being careful not to split the rock which is in the middle.

What I see more disturbing than a slight tilt of the Lighthouse is the divided center of interest!! you have the lighthouse on one side and the Sun on the other divided by the rock mound.
While the image is beautiful my eyes keep jumping around.
