• MATERIAL :- Brass
• SIZE :- Open Size Is 15 Cm, Close Size, 7Cm, Dia 3 Cm
• NAUTICAL TELESCOPE :- Early Telescopes Were Primarily Used For Making Earth-Bound Observations, Such As Surveying And Military Tactics. The Initial Telescope He Created (And The Dutch Ones It Was Based On) Magnified Objects Three Diameters. That Is, It Made Things Look Three Times Larger Than They Did With The Naked Eye.
• USE :- Telescopes Have Also Helped Us Understand Gravity And Other Fundamental Laws Of The Physical World. Some New Telescopes Allow Us To Study Objects In The Universe By Detecting The Heat Or Radio Waves Or X-Rays They Emit. Telescopes Are Now Discovering Planets Around Other Stars.
• SPY GLASS :- Fully Functional Spy Glass Focuses And Magnifies. Simply Adjust The Telescope Tube Length To Bring Image Into Clear Focus. This Telescope Uses a Push-And-Pull Mechanism To Focus on Distant Objects. You Need To Pull It Out Completely And Slowly Push The Barrel Inside, While Looking Through The Telescope, Till The Desired Object Becomes Clear.

• International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.

• UNIVERSAL COMPATIBILITY: Suitable for all types of telescopes including reflectors, refractors, for Dobsonians, for Mak Cas, and for , fitting telescopes with an outer diameter of 63 to 89mm. The focusing mask can be easily installed on any telescope with 3 bolts.
• FOCUSING: The Bahtinov mask eliminates guesswork during focusing, overcoming visual conditions to quickly and easily achieve optimal focus for your telescope.
• SECURE GRIP: Three metal columns of the mask clamp the telescope to prevent slipping while keeping the mask perfectly centered. The 3 column design allows for central alignment and compatibility with a wider range of telescopes.
• DIFFRACTION PATTERNS: The focus fishbone acts as a set of artificial . As light passes through the fishbone plate, it diffracts in 3 different directions, creating 3 pairs of rays. With focus adjustments, the ray patterns move until the 3 sets of rays align, indicating proper focus.
• LIGHTWEIGHT AND ALUMINUM ALLOY: The telescope focusing mask features a thin and sturdy design made of 1mm thick aluminum alloy material, lightweight and to maintain balance without damaging the telescope.

• Brand: United Scientific
• Supply Double Convex Lens, Glass, Unmounted
• 100mm Dia / 200mm Fl, Each - USS

• Color: Transparent; Material: Glass; Focal Length: 100mm; Overall Size: 50 x 9mm / 1.97 x 0.35 inch(OD*H); Packing List: 3 x Glass Len
• Advantage: Made of quality glass that is durable, scratch resistant, and provides excellent optical performance. Round edges have been polished, it is not easy to hurt your hand when you assemble it. The double convex shape of the lens provides a wider field of view, resulting in clearer and sharper images. The lens is accurately measured and has consistent curvature, ensuring consistent performance and results.
• Instruction: Once you have determined the focal length, position the lens in front of the light source. The side of the lens that is curved outward should face the object you want to focus the light on. Move the lens back and forth until the image of the object is in focus on the screen or surface.
• Application: The double convex lens is a type of lens that is thicker at the center than at the edges and is used to gather light. It can make telescopes, suitable for a variety of applications, including scientific experiments, photography, and optical instruments.
• Note: Remember to handle the lens with care to avoid scratches or damage to the surface.
