These tubes are made in Germany with non compromising, mechanical quality.
The tube and dewcap are painted, the metal parts are black powder painted , the tube rings are made from CNC mashined alu, black powder painted . The dewcap slights smoothly over the tube without producing any paint scratches. The focuser have a full size 3.5" to cover our 6x7 fieldflattner without vigneting. It rotates smoothly and with zero shift in an special housing.
The zero shift rotation is very important when your camera has already gotten its best focus and you would like to rotatate your camera into the best position.
The finderbracket have an quick exchange styled screw on system and is mounted on the rotatable focuser, which allows due focuser rotation to bring the finderscope in the most comfortable observing position.
The focuser comes with large anadized focuser knobs and moves as smooth when racking in as when racking out. The focuser comes with a screwed on 3.5"/2" adapter and a adapter 2"/1.25" with inside brass clampring to protect your eyepieces and diagonals from scratches.
The tube rings are on both sides flat and have on both sides 3 threads 1/4-20 inch with spacing of 3,2 inch for outer both threads. The center thread can be used for different mountingplates with only one hole.
The tube internal baffles are matched for our large usesable photographic field and for non-straightlight observing, this system with the matched field flattner for 6x7 format offers a not at all vigneted image circle for any 6x7 camera. No light fall-off.
