Science Education Supplies By Neewer

• For Reflector Telescopes NEEWER LS-T9 1.25\" Red Laser Collimator allows you to fine tune the optics of your reflector telescope and align the telescope's optical elements along the light path for sharp, detailed images. A 2 inch adapter makes it compatible with Newtonian Schmidt Cassegrain and more different telescopes
• High Collimation Precision With an ON/OFF switch, the collimator only has 1 brightness level for simple manual calibration. A side window allows you to view the 45 target and check if the laser is accurately reflected. The laser appears as a clear dot rather than a blurred ellipse for precise collimation
• Three Adjustment Points Should any misalignment occur, use the included L shaped hex key to rotate the collimator through three hex holes for precise and effortless calibration
• Suitable for Various Weather Conditions Even under wide temperature differences, the precision of the collimator will not be affected. Suitable for various weather conditions, the collimator can withstand extremely cold temperatures down to -22?F/-30 degree C and still deliver optimum performance
• Solid Aluminum Alloy Build Featuring a sturdy aluminum alloy body, the collimator is crafted with CNC precision machining for a sleek construction and a small weight perfect for outdoor astronomical observation

• Fit for 1.25\" Eyepieces Compatible with all 1.25\" eyepieces and telescope focusers
• Work with Refractor Telescopes This diagonal telescope mirror is only suitable for refractor and catadioptric telescopes, not recommended for reflector telescopes
• Achieve Optimal Positions When the diagonal mirror is installed on the vertical axis, you will see an upright image with a mirroring effect (left to right reversal). When installed on the horizontal axis, the image will appear in an upside down orientation. No matter how you install the diagonal mirror, you will get an optimal position for observing landscapes, wildlife, and astronomy
• Secure & Safe Installation Directly insert the silver end into a 1.25\" telescope and fasten the telescope eyepiece with the screw knob. The copper ring offers great securing strength and keeps the eyepiece in pristine condition free from scratches
• Impeccable Image Quality The diagonal mirror is made of quality optical glass with coatings for crisp and sharp images as well as high color fidelity. The durable construction is suitable for outdoor use

• Effective 16\"/400mm Heater Length Eliminate dew, fog, and condensation with our specially crafted lens warmer during cold weather photography. For optimal performance and even heating, it is recommended to use on lenses or telescopes with a circumference of up to 15\"/375mm and a diameter of 120mm
• USB Power Source Plug into a USB power adapter, a portable charger, or other power sources that offer a USB 5V 2A output. The 4.9ft/1.5m long USB cable makes the heater ideal for indoor and outdoor use
• 3 Temperature Levels A temperature regulator offers 3 settings (High Mode: 55-65 C; Middle Mode: 45-55 C; Low Mode: 35-45 C) to suit different weather environments
• Touch Fastener Design With handy touch fasteners, the heater can wrap around your lens or scope with security and is easy to adjust
• For Other Applications As a multipurpose heater with a whole length of 20\"/500mm (including the fastener part), it can also keep your baby bottle and coffee cup warm in winter days, or warm up your wrist, elbow, and ankle when they feel cold
