The objective is flipped over to show its back portion where it will be attached to the 5" OD aluminum tube. The color of the exposed areas of the objective's cell is grayish-green in appearance. This is NOT the color it will remain. I will change it to gloss black where it matters most; around the exposed transition rim, between the main tube and dew shield. Looking down through the back end of the cell, you can see a hole in the side wall. This is one the tube mounting holes. There are three holes for this purpose.
