If you're looking for the detailed surface views and a close up look at prominences like solar flares, you need an h-alpha scope. These scopes are highly specialized and filter out all light except for bandwidths associated with hydrogen, the most abundant element of our sun. These scopes will give you mind-blowing views of incredible solar activity. You can pair them with a simple manual mount, or a dedicated solar tracking mount like the Sky Watcher SolarQuest.
Any of these options will let you take some great ell phone pictures of the sun. Let us know if you are interested in more advanced solar photography, we're always happy to help!
