Got a chance to look at the Sun at lunch time today.
The image was taken with a Canon 400D through a 150mm SCT at f/6.3 with Baader solar film filter. I stacked 20 jpegs with Registax 6 and adjusted the curves and hue and scaled down to reasonable internet size with Gimp.
By the way, has anyone else found Registax 6 is a massive improvement over R5 for these large images? So much faster, and handles so many alignment points with ease.
