Here are some more images taken from 2930 m high at St Véran site with the 300 mm solar telescope. The seeing conditions oscillated continuously from very bad to excellent.
The first image was taken in G band (430 nm FWHM 1.9 nm). The resolution is limited by the 300 mm aperture of the scope. There are many filigrees in the intergranular region embeded in the group of pores.

The second image was taken in K-line (which is not Ca K ..) at 396 nm FWHM 10 nm. This is my very first diffraction limited image taken with the 300 mm in this wavelength :-)

The resolution is a tad higher compared to 430 nm. The filigrees are also visible, with some more contrast.
Meanwhile, the area of AR2720, also taken at 396 nm, was crowded with filigrees :

Clear skies !
