No ja niejednokrotnie widzialem te same szczególy przy gorszym seeingu lub planetach nisko nad horyzontem nawet w skrajnie róznych aperturach.
Jeszcze moze cytat...
"The real test of a good optic versus a mediocre one is that the image will stay relatively unaffected by small distortions in the upper atmosphere. If the optic is essentially perfect, and you add 1/4 wave of atmospheric disturbance, you will still be essentially diffraction limited and will see 80% of the image detail at any magnification
If, however, the optic already is degraded by surface errors to ¼ wave, and then you add another 1/4 wave of atmospheric disturbance, the resultant image will not be diffraction limited, and detail will be much more degraded. If the seeing is 1/2 wave and the scope is ½ wave, then you will see almost nothing.” Roland Christen AstroPhysics.
