It can remain in focus for a longer period of time and long exposure images will stay clear and in focus. The new linear power focuser utilises 4 precision ball bearings to support the drawtube and provide great stability and zero image shift while supporting a heavy eyepiece or camera. Adding to your cart. Carbon Fiber Is An Ultra High Strength Material That Is Costly But Gives Improved Performance Overall. Sky-Watcher - The worlds largest telescope manufacturer. This 10” Newtonian telescope … The new linear power focuser utilises 4 precision ball bearings to support the drawtube and provide great stability and zero image shift while supporting a heavy eyepiece or camera. It features paraboloidal primary mirrors made of Low-Expansion Borosilicate Glass resulting in substantially shorter cooling-down times. It comes with an impressive 0.5 mm Ultra-Thin Secondary Mirror Support and it is 77% more Light-Gathering than 150mm. This correction is desirable for visual use as well as when you want to shoot to the edges of the field for some deep-sky imaging work. One of the main advantages is that the focus remains unchanged and completely stable overnight, you will not need to re-focus. This is especially important for astrophotographers dealing with long exposure times. With a carbon fibre tube, it can remain in focus for a longer period of time and long exposure images will stay clear and in focus. 110-pound (50 kg) Payload; Belt-drive on Both Axes Imaging telescopes made of less thermally stable material can deviate from optimum focus after long time exposures. Carbon fibre is a strong and lightweight material and has much better thermal stability compared to a steel tube. With a carbon fibre tube, it can remain in focus for a longer period of time and long exposure images will stay clear and in focus. Astrophotography Reflectors. Skywatcher Quattro 200 Carbon Fiber Reflector. The new Sky-Watcher Quattro Imaging Newtonian with dual-speed focuser incorporates a superb mirror-set with two significant advantages over competing products. dealing with long exposure times.
