Optical Filters 1.25 Baader LRGBC Filter Set (L is UV+IR blocked, C is unblocked, all AR coated, optically polished, mounted in cells) 5 filter set.

These economical single axis (R.A.) DC motor drives are designed to compensate for the earth's rotation. Their rotation speed matches the earth's rotation rate for stars to appear stationary in telescope eyepieces. With the 9-volt alkaline battery (included) installed, it lasts up to 40 hours.

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.

Stray light is eliminated by the fold back rubber eyecups standard with every SP eyepiece and all but the lightest three models feature the security of ruber grips. The focal length available at 40mm, 32mm, 26mm, 20mm, 17mm, 12.5mm, 10mm, 7.5mm, 6.3mm. The apparent field of view is 52 degrees.

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.

Telescope Tripod AZ4 Alt-azimuth mount features separate clutches on both the Altitude and Azimuth axes and a panning arm, which can be fixed in two separate positions. The movements are buttery-smooth and telescopes can be manipulated with effortless precision. Telescope OTA is attached to the mount via a standard Sky-Watcher dovetail bar. Also supplied with this mount is an L-bracket which allows the easy attachment of a spotting scope or camera. Available in two versions: 1) With lightweight aluminum legs for optimum portability, and 2) With 1.75 stainless steel legs for maximum strength and stability.

These dual axis motor drives, designed for NEQ3 and EQ5 mounts, are essential in long-explosure astrophotography. They precisely control the telescopes tracking speed to compensate for the earth's rotation during long exposure of celestial objects. Available in 2x, 4x, and 8x speeds through the Hand Controller. These DC motor drives run on 4 "D" cell batteries (not included). Motors for both axes, clutches, cables, hand controller, and battery case are included.

Available for NEQ3/EQ3-2 and EQ5 mounts.

Polarizing Filters These high quality anodized aluminium, optical glass variable polarizing filters are designed to reduce the amount of light entering your eyepiece. When observing bright objects such as the Moon or certain planets, you can progressively dim the view to a level according to your needs, whilst increasing contrast.

Narrow Band Filters Baader 1.25 Narrowband set, Set of 3 Baader Narrowband CCD-Filters (HaOIIISII).

Optical Mounts The new iOptron SkyTrackerTM camera mount is the perfect accessory for astrophotography. This portable mount makes it easy to take long exposures of the night sky without streaking or star trailing. Simply attach your camera to the front and turn on. The mount's slow-motion motors keep your camera tracking as the Earth rotates for beautiful images of the night sky. The SkyTrackerTM mount runs on 4AA batteries for portability at any location. Now you can take photos of the night sky like never before!

Dome CoversTM give your personality, perhaps a space ship or an Earth, and attract attention. They provide a theme to match the experience inside the dome and encour- age visitors to come over and investigate. The Dome CoverTM comes to the bottom of the dome and around the entry airlock door.

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.
