M75 Helical Focuser [7875]

New 3″ focuser is scheduled to come up next month. M75-threaded ring is removable. So switching male/female allows to set focuser’s direction either way depending on user’s favorite. That should be good benefit.

3″ focuser should be 1st practical step for future’s 3″ reducer & flattener when(or if) the large format camera will be getting popular.
