This image taken in Hydrogen alpha, shows a spectacular prominence associated with the movement of the large prominence across the western limb on Sunday morning. Arthur.
I have tried to image the sun with a 80mm Lunt and an Atik 314l+ mono CCD. I get nowhere near the resolution you appear to do! I guess you're using a mono camera and using curves?
In any case, please can you direct me to a good image processing guide please Arthur (or anyone else). I only use mono CCD (Atik 314, 414 and DMK). Any help would be very much appreciated!
