Product description Classy CNC Tube Rings with elegant design and uncompromising quality A beautiful telescope should be attached to the mount with perfect tube rings, too. Here, a beautiful look is as much in demand as gut technical properties. The CNC tube rings fulfill these requirements. The tube has only 8 mm distance to the bottom side of the rings, thus the mount is not additionally loaded by unnecessarily long levers. The tubes have plane support surfaces on both sides with five female M6 threads on each side. 1 M6 thread in the middle, 2 M6 threads at a distance of 19 mm from the middle, 2 M6 threads at a distance of 30mm from the middle. With this, you can easily attach dovetail bars and accessories. With only 5 mm thickness, the rings are lightweight yet very stable A thin layer of felt was put on the inside of the tube rings for avoiding scratches. However, the tube is clamped very well in the rings and does not change position. That is important if a guiding scope is attached to the rings. Delivery contents Set of 2x Aluminium CNC Tube Rings

Classy CNC tube rings with elegant design and uncompromising quality from TS Optics A beautiful telescope should be attached to the mount with the finest tube ring. Here, a beautiful appearance is as important as good technical properties. The CNC tube rings from TS meet these requirements. ♦ The tube is attached to the mount or the dovetail via a largely dimensioned support surface. ♦ The rings have identical support surfaces on top which allows attaching dovetail clamps or another dovetail bar. ♦ The rings can be folded open, thus the telescope can be removed from them within seconds. ♦ A thin layer of felt was applied to the inner side of the rings. This prevents from scratches. Nevertheless, the telescope tube is clamped very well in the rings and does not misalign. This is important if a guiding scope is attached to the rings. ** 1 Piece **

Baader T2 Extension Tube #25A, Length 15 mm

Item condition: new, but not original packed

ASI T2-Tilter - Tilt flange Adjustment of image plane and sensor position Many astrophotographers know the problem: You focus as good as possible and in 1-2 corners the sharpness is still not satisfying. The result is a bad compromise, by changing the sharpness setting until the stars appear relatively evenly "sharp" or by simply cutting away the corner. Some possible causes of this problem: ♦ a slight tilt of the camera sensor (only a few fractions of a millimeter are enough) ♦ a tilt of the focuser ♦ a slight tilt of the field plane of the telescope (very common with Newtonian telescopes) ♦ a tilting of the eyepiece-side accessories during clamping This is the solution: With the ASI T2 tilter you simply adjust the chip of the camera to the field of the telescope, no matter where the cause of the tilt comes from. You only have to keep the orientation of the whole adapters, correctors and camera. Connecting the camera to the tilter: In principle, any suitable camera can be connected to the tilter via the T2 thread. However, additional bores also allow the connection directly to the camera body on the following ZWO cameras: ♦ ASI294/ASI1600/ASI183/ASI533 Pro cooled ♦ ASI294/ASI1600/ASI183/ASI174 uncooled With the ASI071 and ASI 2600 Pro the housing is differently dimensioned, the direct connection does not work. There it only works via the T2 thread.
