I am old enough to remember a time when white-light solar filters were pretty much the only filter option for most amateur astronomers. I was working for a telescope retailer at the time when the Coronado P.S.T. first came out. Over the last 20 years, we have seen H-alpha and CaK telescopes become mainstream.
In 2016, I decided to get into serious solar astronomy in time for the Mercury transit. I made solar filters for my camera lenses and bought a Coronado P.S.T. for myself. Sometime later, I bought myself a Thousand Oaks Solarlite filter for my 102 mm Sky-Watcher and I enjoy it very much.
I no longer have the Coronado P.S.T., but I am content with white-light observing and photography. I recently bought a glass solar filter for my Sky-Watcher telescope from Spectrum Telescope as I wanted a spare filter.
Photographically, my "dream setup" is my Sigma 150-500 mm lens with a 1.4x telextender and a Silver Black Polymer Thousand Oaks filter. I stack images in Siril and process images in GIMP. I also use my smaller lenses for quick image stacks when I am short on time.
These are my most recent high resolution images taken with my Sigma lens. I am currently doing my own personal solar monitoring project, photographing the Sun as much as I am able as time permits over one or two solar rotations.

My main motivation for getting into solar astronomy is the reality of light pollution. Solar astronomy gives the amateur astronomer the ability to experience undiminished astronomy unlike deep sky observing near urban areas.
What's your solar story? How did you get into it? What filters do you use? I would be interested in hearing from you.
