On the 8th August there was this huge sunspot group called AR2396 that was over 150,000kms in diameter with a dark core that was the size of three Earths. Not only that, the pattern of this large sunspot group looked like a little footprint :-)
The white light image was taken with a Meade 80mm refractor telescope fitted with an Orion glass solar filter. I used a Canon 700D camera with a 2x and 3x Barlow lens attached, the exposure time was 1/640th second and ISO 200. There were 25 images stacked in RegiStak6 and then processed in PS CS4.
The other two images were taken with a Lunt 80mm H-Alpha solar telescope that shows the solar surface and faint wispy prominences in all their glory. Both images were taken with a Canon 700D camera with a 2x and 3x Barlow lens. I use this camera because it so easy to capture the images with out a computer and it’s very light on the back of the telescope.
