Product description TS Optics Off Axis Guider with Zeiss M68x1 connection - short design Off axis guider for large cameras This big off axis guider with Zeiss M68 thread connection is a consequent further development of the short TSOAG9. This model is designed for heavy cameras with large sensors. With an optical length of 16.7 mm, it also needs not much back focus. But nevertheless, it offers all options needed for professional tracking. Advantages and characteristics M68x1 Zeiss thread on both sides Length 16.7 mm only (w/o male threads) Choice of three positions (120° each) for the sidewards T2 guiding cam adapter, thus you have always a good framing option for the sensor Free aperture of 62.5 mm: even large camera sensors can be used without vignetting Massive design: all connections are screwed, no clamping. This is ideal for heavy cameras. The guiding focus can be adjusted individually The prism can be shifted in order to reach an optimal position relative to the main sensor Internal surface with anti-reflective thread Three connections for the prism tower Due to the massive design, this OAG has no rotation functionality that could compromise the solid connection of heavy cameras. Three positions (3 x 120°) can be used for the guiding tower. Inappropriate prism positions relative to the main sensor (e.g. in front of an edge) are prevented. If the guiding cam collides in one position with the main camera, another position can be chosen. The two holes not in use can be closed to prevent stray light from entering the system. Short design The off axis guider is consequently designed for short design without compromising its stability or ease of use. All elements can also be operated when wearing gloves. Distances to prism Distance from female M68 thread to prism center: 11.5 mm Minimum distance from prism center to T2 thread: 27 mm Delivery contents Off axis guider
TS Optics Adaptor M42x1 female / EOS EF Bayonet with 0 mm optical length This adaptor screws directly into the Canon EOS body and enables you to connect objectives with M42x1 thread. Please note: The adapter does NOT work with M42 lenses with a very large diameter, e.g. MTO1000, Rubinar 500 and Rubinar 300
TS Optics Non rotating helical focuser with M48 connection A true helical focuser like this works like a camera objective - when you turn the focusing ring, neither the lens nor the camera (or eyepiece and diagonal) will rotate. The only motion is in and out. The advantage of this helical focuser is the fine adjustment, possible in part due to the fine pitch of the focusing ring's thread, and in part due to the large diameter of the ring. In the case of this helical focuser, virtually backlash-free movement and graduated markings on the focusers allow repeatable return to the focus point simply by noting the focus position reading. Advantages at a glance no rotation of the diagonal or camera - the only motion is in and out precisely adjustable limitedly self-locking wide focus range: 40 mm 51 mm minimum height, 91 mm maximum height easy adaption to the telescope tube and the camera good solution for telescope or objective self construction M48x0.75 (2" filter) threads at both sides, with all adaption possibilities generous clear aperture of 45 mm also suitable as variable M48 extension 51 mm to 91 mm for the perfect working distance two screws for locking the drawtube Wide focussing range and short length The Helical focuser has a wide focussing range of 40 mm, but it is very short, with a minimum height of only 51 mm. So you can use the focuser on telescopes or telephoto lenses with little space to the focus point, like Newtonians. Accessories This focuser is not suitable for heavy accessories, it will tilt. The main use is with small CCD cameras for planetary photography, 1.25" eyepieces and lightweight 2" eyepieces. Delivery contents Helical Focuser with 2 locking screws
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
