| Astronomical Primary Mirrors: | ||||
| The primary mirror is the most important component of any reflecting telescope. Our primary mirrors are made by experienced opticians and are guaranteed to meet the theoretical limits of the resolution for their aperture. They are ideal for home-built Newtonian or Dobsonian telescope projects. Each mirror is precision ground and polished from Float glass blanks. The figure of each mirror is tested to ensure it meets the specification before proceeding to aluminization. Aluminum coated to a minimum 89% reflectivity and then over coated with transparent silicon monoxide for a durable, lasting finish. Mirrors upto 10-inch diameter comes in standard f/ratio as mentioned. Larger size mirrors are made to order with customized f/ratio and thickness. |  |

| Mirror Star Diagonal : | US$7 | US$25 | <1 lb | |
| This precision 90 degree star diagonal feature fully coated mirror, delivering superior image fidelity. It lets you view objects that are at a 90 degree angle from the direction the Telescope is pointing, thereby allowing comfortable viewing when the telescope is pointed at or near Zenith (i.e. directly overhead). The resulting image is right side up but will be reversed from left to right. Housing are black - ABS plastic so no thermal expansion during those cold nights. A thumb screw to secure the eyepiece in place. |  |

| Plossl Eyepieces 1.25" | ||||
| You don't have to spend fortune for good quality oculars. Our Plossls are attractively priced for even limited budgets. Their 3 and 4 elements glass lens configuration provides a pleasing 52-degree and more apparent field of view, wider than that of many pricier eyepiece designs. The lenses are carefully ground and polished from quality optical glass to provide excellent image sharpness and brightness. They are fully coated with anti reflection material to maximize transmission of incoming light and improve image contrast. The anodized barrels are precisely machined and internally blackened to prevent stray light reflections. They are also threaded to accept standard filters. Whether you are looking to upgrade from lower quality eyepieces or just want some good reliable oculars at a reasonable price, you can't go wrong with our Plossls. We offer six different focal lengths from low power general purpose 40mm and 32mm to the high power 6.3mm. Get all five and you will be set for any observing challenge. |  |

| ASTRO EYEPIECE 1.25
inch OD: Are you in need of a good quality eyepiece / Barlow? Do you want to upgrade the magnifying power of your telescope? We offer fine standard eyepieces and Barlow lens for your telescope. Our reasonable par-focalized eyepieces are manufactured with a 1.25"OD American Standard barrel diameter. Ramsden Eyepieces are available in focal lengths of 38mm, 32mm,25mm, 16mm,12mm, and 9mm BARLOW LENSES: One of the most useful and cost effective tools in an amateur astronomer accessory case is a good quality Barlow lens. It is a simple concave (negative) lens or doublet that increases the instrument's effective focal length boosting the magnifying power of any eyepieces. Using a 2x Barlow your 12mm eyepiece effectively becomes a 6mm eyepiece. Also increases eye relief. Here We offers four variety of Barlow lenses in 1.25inch OD are available with 2x, 3x, 4x and VARIABLE Power (1.5x = 2x = 2.5x = 3x ) |

| Universal and Specified Camera Adapters | US$20 | US$25 | <1 lb | |
| Universal Camera Adapters (A) : These
adapters allow attachment of a 35mm SLR camera body to
reflector and refractor telescopes for which T-adapters
are not available. The adapter slides into the eyepiece
holder as an eyepiece normally would. Each adapter is
precision made of black-anodized aluminum. Specified Camera Adapters (B) : We now provide specified camera adapters for most of the standard makes. These adapters comes along with T ring to fix onto the specified SLR camera body. The adapter slides into the eyepiece holder as an eyepiece normally would. Each adapter is precision made of black-anodized aluminum. Please mention the make and model of your SLR camera |

| Eyepiece-projection tele-extender | US$30 | US$25 | <1 lb | |
| A tele-extender is an eyepiece-projection tube used for high-magnification photography of the Moon and planets. The adapter slides into the eyepiece holder as an eyepiece normally would. All models are composed of two detachable parts: a T-adapter for prime-focus photography, and an extension tube for eyepiece-projection photography. A setscrew in the extension tube holds the eyepiece in place. Each adapter is precision made of black-anodized aluminum. The 1.25" models are threaded for eyepiece filters. A T-ring, sold separately, is required to couple your 35mm camera body to the universal adapter. |  |

| Moon Filter 1.25" | US$20 | US$25 | <1 lb | |
| MOON FILTER The MOON FILTER is a precision neutral density filters that spreads the Lunar intensity uniformly over the visual spectrum. When the Moon is full or nearly full, it's disk appears blindingly bright with reflected sunlight. The glare washes out most of the craters, and other surface details. Moon filter reduces glare and intensity, thereby enabling you to study Lunar features in greater comfort and without spoiling your night vision. Reduces irradiation, which is the distortion at the boundary between light and dark areas such as along the Lunar terminator. For Visual use simply thread these filters into the 1.25" eyepiece barrel of any imported Astro Eyepiece. |

| Astro Solar Safety film Filter | ||||
| Astro Solar Safety film Filter: See the Sun Safely, In Natural Color Who said you have to be in the dark to do astronomy! Turning your telescope to the Sun is fun and educational. Watch the march of giant sunspots, the clouds of glowing vapor in the photosphere, and solar “granulation” detail. But be sure to protect your precious vision with a safe Astro Solar Safety film Filter! Looking at the Sun without one, even for an instant, can permanently damage your eyes. Specially CE-tested safety film with high quality optical characteristics reduces intensity of sun light by 99.999%. Astro Solar safety film is a specially manufactured streak and blister free foil only 0.012mm thick and attains the optical quality of plane parallel glass filters. The base material is not Mylar. The highly uniform molecular structure of this material is the result in nuclear elementary particle physics. The coating is subject to constant quality control. It’s reflective property of over 99.999% has been the German Republic Bureau of Standards and conformity with EU norm 89/686 is certified with CE symbol. It reduces the intensity of sun light by factor of over 100,000. Coating on both sides of the foil ensures a highly uniform filtering. While neutralizing the occasional microscopic holes in the coating (which are also much more present n glass filters). One layer of this foil is sufficient for the construction of a safe, high resolution solar filter. The quality of the solar image is immeasurable, better than what can be achieved by using a so-called Mylar “rescue blankets” or similar materials, which must be used in several layers. Base Astro - Solar is extremely clear and homogenous. It is specially treated 1) To absorb internal reflections (reducing haziness present in other films). 2) To reduce internal stresses which dramatically improve the optical performance over Mylar and similar filters. 3) Gives neutral white image of the Sun without any colour, against a black background sky. Astro-Solar filter is a very flexible substance by nature. When mounted in the filter cell, it will be quite wrinkled. Don’t be upset by the appearance because the best resolution is obtained when the material is slightly relaxed or wrinkled. |
