Hi, Welcome to the Astrophotography Section of UHH!
There are many others here better versed than I in shooting old Sol.
I did not see Solar filters in your equipment. You MUST use solar filtering.
I got lucky with my earlier set up, an 80mm CF Refractor Triplet telescope.
I bought a ring mounted Solar film filter, then mounted it into a piece of 4" PVC.
That fit over my Telescope, and inside of my Tamron 150-600mm lens. A two-for-one.
The size of your filter depends on the lens you decide on. If really undecided, consider renting equipment compatible with your camera gear.
Practice, Practice, Practice. You can practice at home easily while you prepare. To work out any changes or bugs that crop up.
I have a new larger telescope this year I am really enjoying. I bought a mounted solar (glass) filter to fit it in hopes of catching what I might of the event. I'll be in my Backyard, again.
Best of luck! Enjoy your planning, and especially the event of the Solar Eclipse!
(PS: if you have the means, you might want to consider a dedicated Solar Telescope, and make a real hobby of it.)
Edit In: You might find a Hilio pod as invaluable as I do. Saves a lot of trial and error when getting on the sun.
Does your mount do solar tracking?
