Hi all,
Hopefully an easy question to answer. I have a Sky-Watcher Black Diamond ED80 that I intend to use for astro-photography. I have been trying to find out what the back-focus is but am struggling to find anything (yes I did a Google search).
If anyone knows, would be grateful if you could let me know.
