SP series eyepieces set the performance standard for modern telescope oculars. The proven 4-element Plssl design delivers edge-to-edge blackened elements deliver the highest contrast images attainable. SP series eyepieces minimize spherical abberation, distoration, astigmatism and off-axis color white oversize optical elements afford the observer luxurious eye relief.

Eyepiece This 10mm Erecting Eyepiece can be used on any telescope, refractor or reflector to correct the orientation of the image. On a refractor: The erecting eyepiece can be used on any refractor, even a short-tube. It works alone without a diagonal. The extension tube is needed only when focus can not be reached by using the erecting eyepiece alone. On a reflector: With the Erecting Eyepiece attached to your Newtonian telescope, images are easily corrected while still maintaining their quality and clarity.

Pyrex Tube The Sky-Watcher 10 Dobsonian features a primary mirror made of Pyrex glass. Because of its very low coefficient of thermal expansion, Pyrex glass is less affected by changing temperatures. This greatly reduces the cooling time of a telescope larger than 8 in diameter without using an extra fan. The great stability of this low expansion glass ensures high quality images. It is also substantially more resistant to scratching then plate glass.

Cs Mount Camera No one want to lost the frame in long exposure.QHY178, QHY290, QHY224 COLDMOS camera has built-in 128MB DDRII image buffer. To compare with the non big buffer camera, This memory will cache the image and avoid the frame lost. And this buffer allows the low performance computer and USB2.0 socket working.QHY174 COLDMOS camera has two version. The standard version and the GPS version. The GPS version has the build-in GPS module to mark the high persion time information (up to 1 micro-second) to the image head. QHY174-GPS is the world first GPS pps based high percison hardware timestamping camera which is idea for occultations, transits, realtime 3D meteor flying capture, UFO 3D tracing, satellite 3D tracing, unmanned aerial vehicle 3D tracing monitor etc.
