AR1731 and a nearby prominence

A DMK21AS camera fitted with a 2.5x Barlow was attached to a Solarmax ll 60 BF15 H-alpha solar scope. A 10,000 frame AVI was captured of the Solar disk region containing AR1731 and a 5,000 frame AVI captured of the prominence. The data were processed in Registax 5 and the two images combined to give a single image. The image was colourised to represent the wavelength used:

Sometimes the structure can be more clearly seen in a negative image:
