An eclipse with sun-spots visible @840mm. A few minutes before the big event on April 8th of 2024, I took this in Fredericksburg, TX. I thought this angle brought the best view of it. I was using a White-Light Mylar style filter, fitted on the end of my Tamron Lens Hood. Then I gave the image an Orang-ish color.

The weather held out for us until Totality, then after Totality our show was over. Clouds rolled in. In my profile I posted a Totality picture as well.

Generally with the Sun they will tell you Manual Focus is required. But few will tell you how difficult it is to get the focus exactly right at 840mm. I actually made a Youtube video with a technique for long lenses like mine where I take the collar off the lens, and fit this Gear Ring over the Tamron's focus ring. Don't expect just moving the focus wheel to 'infinity' will have desired results. Perhaps with newer equipment, it might be possible to Autofocus.
If you didn't know artificial computer assigned colors are often given to Astro images just for aesthetics. Colors you may have seen in pictures from Hubble and James Webb are all artificial. We see an orange sun with our eyes, only because of our atmosphere, and we enjoy that color (i think), so many of us choose to color our pictures that way including me. If I decided to use an inferior ND filter it would have came out different shades of 'orange'. There are other types of filters that would give it other colors, including 'Blue'. The most expensive hydrogen-Alpha filters, would have given it a 'deep red' look with more detail. Really our Sun is 'White' despite what Superman tells you.
