Hi Aram, Peter!
You wondered what it might do to the shutter in a camera.
If the shutter is metal (think Nikon F's titanium foil shutter or a metal
Copal-square) then, not much.
The newer, lighter, plastic bladed focal plane shutters might be a problem if
not protected by a mirror.
Years agim I burned a hole in my Leica CL's cloth shutter, while focusing on a
sunset in the Caribbean.
The sun can be dangerous to cameras!

What kind of camera? If mirrorless you are just fine. You can also use------
live view on a DSLR. A filter like you would use for a solar eclipse
will give you nothing. There is no real danger in looking through a
viewfinder quickly to line things up. I do it all the time when
shooting sunstars. Just don't stare at it. Might want to cover the lens
between exposures. Not sure what it might do to a shutter curtain or
sensor depending on the type of camera, since you will have it set up
day long. The wider the angle, the smaller the focus spot of the sun
will be, and probably more concentrated. Like burning ants, though as I
have grown up, I find it not so appealing anymore :-( I think of all
the ants I incinerated in my youth and am sorry.
What are you wanting the output to be? Do you want to put them all
together to make a multiple exposure on one frame? I am assuming you
will have it set on a tripod and always pointed at the same landscape
and just have the sun moving across the frame. Might have to shoot in
manual mode to keep exposure the same.

Subject: [LRflex] Seeking Safety Advice For Filters For Landscape Images
Concentrating On The Path Of The Sun
Good afternoon to everyone. Could I please ask for advice on selecting
filter(s) for the following concept for a series of photos? I have found
a hill-top location (kinda rare in south-central Florida) that faces
east southeast with an open view of horizons, and I was considering
trying to take a series of images thru a given day at this fixed
location from before dawn until dusk with a wide angle lens, taking an
exposure every 45 minutes or hour, tracing the arc of the sun from
morning horizon to evening horizon. It wouldn't be exactly "solar
photography" because I'm not aiming directly at the sun with a
telephoto; but something in me head still is concerned about safety of
my eyes and equipment because I've still got the sun in every frame.
Would a designated "solar filter" be too dark to allow the landscape
under the sun's arc to be recorded in the image? Any suggestions or
observations would greatly appreciated. Thanks.
Best regards,
Peter S.------
