A very nice feature for my style is the 2 points of rotation in the focuser assembly.
One adjuster allows for the orientation of the focus knobs and one allows orientaion of a camera or your diagonal. I find this very convenient as to the diagonal. When observing with a go-to mount the orientation of the
The dew shield slides very nicely and has no slop as it moves and when fully extended is one with the main tube.
The interior finish of this tube is outstanding. Light is absorbed very well and looking into the objective one sees a nice dark hole to the rear opening of the focuser. The baffles are well attached with none of the gaps or rough weld points I have seen in some tubes. My unscientific impressions of the Optics are that it is as good or better than my ES120 FCD100.

Views of Saturn and Jupiter with poor transparency but fine seeing conditions were also high in contrast revealing detail in spite of the negative mitigation of the less than fine quality of my sky while doing this viewing.

It functions somewhat like the Baader Twist lock feature, but this is built as part of the focuser. It is a convenient feature and like the other hardware on this
