One of my dream projects.
It would really serve no function other than to introduce people to the monthly movement of the Sun. You would be able to change the changes in the Sun's apparent diameter from aphelion to perihelion.
Alas, only a dream.

Nice work!
I was unable to get the exact dates for perihelion and aphelion exactly, because of our weather, but here is 27th June and 29th December, 2024, taken with my old Samsung Galaxy J through my old Selsi/Towa 60mm, my sunspot telescope.

It meant a lot to me to be able to get this. This winter has been horribly overcast so far.

There is a very slight variation in the apparent size of the Sun at aphelion and perihelion, about 3.6%. While I wasn't able to get two images six months apart on both days, I did manage 29th June and 27th December 2024.
Simple afocal images through a modest 60mm telescope.

It is important to remember that telescopes, even mediocre ones, were once quite pricey. Amateurs of modest means still found ways, fortunately.
Also, I wax between Medieval and Minimalism.

I wasn't expecting to get any sunspot work accomplished today, let alone a picture. Yet, here we are.
I suspect this is it for the remainder of the year.

Incidentally, of the six images I took, this was the best. As you can see, some work was required.

Quite cloudy, but I managed. No large spots, but it is quite active nonetheless.
My image (have to give the photographer credit. He gets crabby otherwise).

Today's Sun, 21st December, 2024. Overprocessed? Yup. I was actually shooting through clouds.
But I did it.

Happy Solstice?
Okay, I almost had a clear shot at the Sun with the Universal/Equatorial. Alas.
At least I was able to record the solstice on my balcony analemma. Sort of (fuzzy shadow).

Happy Solstice! The Sun has cleared its southern most point and will now slowly tread north.
It will get warmer in the north. Eventually. Patience, children.
