Yesterday i tried my Bahtinov mask to focus on capella. It just did not work. through live view , i could see Capella as a point lacking the spikes i needed to focus it..
Racking the focusser in and out only changed Capella to out of focus or in focus, but no spikes.
Eventually i gave up and just focussed without Bahtinov with live view until i have a pinpoint Capella.
I took my pictures.
Sharpness then was not bad
But how do i get the spikes?Otherwise i see no point in using a Bahtinov mask....
