Quote:Your B1800 diagonal and OCS is set up correctly. Lunt advises all users that the diagonal has to be pulled out about half way as the first step in focusing. You then use the focuser.I have 2" extension tubes that I use on my refractors. They are 80mm, 50mm and 35mm in length. The 35mm length 2" extension tube from OPT works perfectly for my Lunt 60. This eliminates the need to pull the diagonal out of the focuser.
