A magnificent active region this one.

Those are fantastic images! But there is no way to tell wtih the huge list of equipment at the bottom what took it?

Made with the CaK diagonal, of course. Great detail. Can't wait to have a go at this AR with my scope, but I have to wait till Friday.

BTW, the image looks like a typical rendering of deeply zoomed-in Mandelbrot set.

Excellent pictures, some fine work!

Thanks folks! Chris, all my Cak shots are taken with the Lunt Cak diagonal and the ST102 f/5 refractor. These were taken with a Cemax x2 barlow. It seems a good time to mention the fact that I CANNOT use the Cak diagonal with the Skywatcher ED80. This is because the ED80 has some light baffles in the drawtube which prevent the nose piece of the diagonal, which is 3.5", sliding all the way in. The same is true of the Equinox and several other Apos. Worth bearing in mind in case there is anyone thinking of using that combo,

Excellent surface detail! The Lunt diagonal is impressive!
