My friend in the USA, Earl Foster, was kind enough to send me the raw data for an image of the sun he took using an Meade 80mm APO refractor, Baader K-Line Filter and DMK41 camera. I am particulary interested in this filter which images with a 8nm passband in the near ultra violet. It is a cheaper alternative to the Lunt range of CaK filters, however has a much wider bandpass and hence less contrast in the image. The raw image was post processed for wavelets in Registax 5 and then final processing done in Photoshop CS4. I'm pretty pleased with the outcome, especially as the sky conditions were rather hazy when this image was taken. I hope when Earl gets some better sky conditions he will forward me somemore data for me to play around with. Thanks Earl!
