AR1057 in Green Continuum light on March 26

Green light is in the middle of the visible spectrum and is a very stable region in which do white light imaging.
An
f/5 6″ refractor was fitted with a photo grade Baader solar filter (not
safe for eyepiece work) and the DMK camera was fitted with a Baader
green continuum filter and a x2 Barlow.
The best 3000 frames out of a total of 5000 were stacked in Registax to produce the final image.
