Visibility IV / V
Sunspot AR2767 photographed in narrowband Ha light. The picture actually became more interesting when I left it popularly in black and white. The AR2767, visible in visible light, appears in black as it should, with the tiny little guy sunspots visible in white to the right. I separated those two little spots only very carefully by detecting the TMB 152/1200 with a lens tube and a Baader Herschel prism (150x magnification). At times, they disappeared into the ripple of seeing, but both appeared with enough diligence to be sure of their existence.
The white disc visible in Ha light visible below these obtained no equivalent in normal light detection. Likewise, the vortices in the center of the top only saw my final image during its processing. In practice, Ha detection / imaging via Quark brought a more interesting result this time than the AR2767, which dominates the view alone in normal light :-)
EDIT: I got more detailed information about this picture from Petri Kehusmaa on the discussion forum, so I will add it here now:
"There are superpenumbra filaments that curve well according to the magnetic field around that dot. The curvature of the magnetic field is caused by the rotation of the sunspot. (Those bright areas are not 'guy sunspots', but
Those visually visible little sunspots are, in fact, also visible in this parallel image, which I discussed today, July 28th. new from the video shot at 10:05. (See the second image of the observation, which now shows the wider area around this comma and also those little spots better highlighted in the direction of 5 o'clock from the main comma.)
