I hope this question won't get me laughed at, but i see posts where people have made excellent images using hours of data.
Is there an upper limit to this?
Can you make unlimited subs of the same object? oh i don't know, say a thousand hours as opposed to tens of hours?
Would this make a more detailed image, more light equals more detail?
Or am i missing something blindingly obvious 😁😁
Thanks for any responses
Tony
