I have owned many diagonals over the years and this is my favourite and the only one that I still own! If you have never enjoyed a "Baader Clicklock" then you are missing out on the ease that you can change your eyepieces at night in the dark and in winter with your gloves on! The construction is rock solid too.
Very well constructed diagonal

This is a very well-constructed diagonal, and yes the mirror is significantly larger than in some other 2 in star diagonals, and will not restrict the field of view of any 2in eyepiece. The stated light path of 112mm is also quite accurate, this can be quite important with refractors where there is a limited amount of travel on the focusing mount, and some manufacturers quote an inaccurate figure or no figure at all.
