This is post processed movie. If you like such a contrast visually, buy two 100mm <0,6A objective mounted filters from Solar Scope, adjust them properly and use a very good blocking filter (narrow enough, but brightest possible, just like my Coronado BF10).Ghost-Fire wrote:This is what kind of detail and illumination I would like to attain with my solar telescope!
The DISK contrast on this video is incredible!

I got two PST etalons with estimated bandwidth of <0,3A and I tried them on a PST post-mod scope. Fantastic contrast.
I also tried a Quark with estimated bandwidth of <0,4A on a scope equipped with 60mm SM60 Coronado filter. The contrast is shocking too.
