In-distinct stars at high mag?
Hi everyone
Just wondering if it's normal for bright stars to be in-distinct (i.e. non-pin point) at higher magnifications e.g. 200x?
For example, viewing Rigil Kent over the past few weeks at high magnification has revealed it to be almost disc-like but in distinct. However when viewed at lower magnification (e.g. 80x), it appears pin point and crisp.
I presume that this is due to poor seeing conditions as in each case I was unable to conduct a star test (the airy disc was jagged and in constant motion), however, thought I'd check as I read something recently about it potentially being due to imperfections in the human eye??
Any thoughts?
