Details:
I recently took delivery of a Player One Apollo Mini camera for my Televue 85 refractor with a 60mm Lunt etalon and 12mm blocking filter. I've been playing with a lot of editing solutions. This image was captured using Fire Capture, 5000 frames in SER format, the top 20% of images stacked in Autostakkert, tone curve edited in imppg, first inverted and then adjusted, with unsharp mask applied. Then exported to TIFF and imported into Lightroom Classic. I set a radial mask to the solar disk, excluding the prominences and beyond, inverted the tone curve of that and then adjusted the texture, clarity and dehaze and then sharpened the final image before export. When I've tried to colorize the image I tend to lose some of the critical detail to the eye, so I kept it monochromatic.
