14-03-13 Today's Sun with Astrosolar Filter only
Taken with a Skywatcher ED80 Refractor and Canon 500D at prime focus ( 600mm ) Baader Astrosolar Film Filter..
Comparing this image with the one earlier with a continuum filter, I have to say that a small scope like the ED80 performs better without it. Waste of money ? possibly. May be of more benefit when using a larger scope which is more affected by seeing conditions. Going to try with my 6" Refractor at a later date. I am willing to concede that the Baader Continuum may make a difference when the seeing is not so good.
Processing the image from the continuum filter is also more laborious as the image is bright green to start with, possibly better to produce image from it in mono, but I don't like drab looking suns :-)
