I have seen mention that it is good practice to initially focus on a bright star (preferably with a Bahtinov mask) as a basis for the rest of the session.
How much (if at all) is it likely that the focus wouid need to be adjusted after that, especially for planets and the moon? Is everything out there at “infinity” focus? It may be a silly question, but I would be interested to hear any opinions, or definitive advice.
Having achieved focus on one object, should the urge to make further adjustments be resisted?
