Nice work Jorge, what kind of solar filter do you use? I assume off axis with the 12" GSO?

Cheers

Thank you, Rusty. I am using baader solar filter. And normally I use OAG. This photo, with Canon, is single: only one frame. And up to now I am not using any guiding to shot the Sun. When I make video, I am doing only 200 - 400 frames, at 10 fps, so not long time to use guinding.
With color camera, no narrow-band filters, only the shape of solar spot. Don't need much time of exposure.
