Although it's fascinating when seen through the eyes of a camera and I can understand people's passion for it.Notice that the focus is better at the bottom left of the frame? It's a shame that I couldn't get focus at the top also. But boy, that lens is heavy, even on the tripod. And wobbly. Just touching it to focus makes it difficult to see. This is a cheaper 500ml lens; I wonder if the better ones have auto focus?  Or do you use a telescope? Can you explain how in a few words?  Cheers, Brad  <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /></blockquote>
