title: Astromania 1.25" 7.5mm 58-Degree Planetary Eyepiece for Telescope
text: From the brand Previous page Astromania Optics Visit the Store What's Hot Visit the Store Sales & Clearance Visit the Store Next page Product Description High end planetary eyepieces are probably amongs the most versatile eyepieces available today. Despite its many possible applications no compromises have been made in the performance. The eyepieces are perfectly suited for observing planets, the moon, deep sky objects as well as for projection photography with DSLR or compact digital cameras. Observing the Moon and the Planets ... a very high contrast and image definition, especially on the optical axis, make the HR Planetary eyepieces the ideal companion for demanding planetary and lunar observing. Due to the very good viewing comfort you can see even finer details without having to strain your eyes. Observing Deep Sky Objects: Nebulae and Galaxies ... compact Deep Sky Objects are often difficult to see because they are often very faint. The HR Planetary eyepieces are fully multicoated and offer a high image definition for a bright and clear image. This makes them ideal for observing such compact objects. HR Planetary Eyepieces - Perfect Viewing Comfort HR Planetary eyepieces were made for best possible sharpness and contrast on the optical axis, as can be expected from good planetary eyepieces. Quite different from most other planetary eyepieces however the HR eyepieces also have a very good viewing comfort, a long eye relief and a larger field of view! Read more Each HR Planetary eyepiece has an eye relief of 16 millimetres and a lens diameter (of the exit lens) of almost 20 millimetres The long eye relief can be perfectly utilized by each user by simply adjusting the extendable eyeguard. By this each observer can find the perfect observing position. That is a feature normally only found in much more expensive eyepieces! The HR Planetary eyepieces are suitable for eyeglass wearers, even the short focal length eyepieces! Read more Features of the Planetary HR Eyepieces: Excellent Image Sharpness: On-axis image sharpness is practically perfect, like a really good Orthoscopic eyepiece. Sharpness throughout the field of view remains without visible deterioration. As a result the eyepieces are considered by many to be even superior to Orthoscopics! No Kidneybeaning: Cheap eyepieces and too extreme wide angle eyepieces often suffer from "Kidney-Beaning". When you move the head only slightly a black, kidney-shaped shadow will cover a part of the field of view. This effect is nearly eliminated in the Planetary HR eyepieces. Suitable for Binocular Viewers: Planetary HR eyepieces are very well suited for binocular viewing. You will have no trouble looking through both eyepieces at the same time without getting into a conflict with your nose. The adjustable eyeguard offers a perfect observing position for critical binocular viewing. Read more Image Quality : Many tests have demonstrated that the HR Planetary eyepieces have an excellent optical performance. Compared with similar eyepieces the HR eyepieces are on the same high level of quality. The eyepieces are sourced directly from the factory as A-grade products. The HR eyepieces are the latest evolutionary step of this eyepiece design. Some other eyepieces may look similar, but they do not necessarily reach the same high performance. Lens Layout: The lens layout of the Planetary HR eyepieces was designed by Thomas Back, a renowned optician who also designed high quality apochromatic refractors! The eyepieces have a long eye relief and a large, perfectly corrected field of view. A particularly important detail: The image sharpness is excellent throughout the entire field of view. Full Broadband Multicoating: Planetary HR eyepieces have a broadband multi-coating on all glass-to-air surfaces. They have an excellent transmission and contrast . Ghost images and internal reflections are effectively suppressed Eye Relief : The HR Planetary eyepieces have a long eye relief of 16mm. The eyeguard is adjustable freely for optimum viewing comfort. Barrel Size : The Planetary HR eyepieces have a 1.25" barrel with safety undercut. Each eyepiece has the standard 1.25" filter thread. Our expert comment: Typical planetary eyepieces usually obtain higher magnification with short focal length, since the moon and planets observers are always in the pursuit of details. You can get the same level quality products in our store at half the pric e of the market now, NEVER EVER MISS IT! Read more

text: From the brand Previous page Astromania Optics Visit the Store What's Hot Visit the Store Sales & Clearance Visit the Store Next page Product Description This Astromania star diagonal has a 1.25" metal barrel. The chrome finish not only looks good, but is also practical, as the star diagonal always remains firmly attached to the focuser. The clamping screws lock the barrel firmly in place without scoring the nosepiece, as is the case with many cheaper products. In short - this barrel will keep your star diagonal in condition for virtually forever.The mirror has had everything that is possible optimised, it is the link between your eye and the telescope - and is hence just as important.Sometimes you do not want to have to re-install a filter every time you use a new eyepiece. Perhaps you might want to observe the Moon today with a range of eyepieces - but with the same filter? That is also possible due to the filter thread provided in the star diagonal. Read more Durable And Sturdy The two mirror tubes are made of metal to make the structure stronger and more durable. Protective coating on the mirror to ensure a long life. Two Eyepiece Holder Thumbscrew There are two screws on each side of the eyepiece barrel to make the structure more stable and durable.

title: Explore Scientific 82 Degree Series Gas Purged 11mm Waterproof Telescope Eyepiece
text: Product Description Explore Ultra-Wide Eyepieces - Comfort, Quality, Value. Explore Scientific 82° Series eyepieces, with their 82° apparent field of view, immerses you in a very comfortable ultra-wide field that naturally promotes relaxation at the eyepiece. When you relax your eyes and take in the scene presented before you, it is much easier to observe for longer periods of time, and details begin to materialize that may not have become apparent to you at first glance. Another great benefit of ultra-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images. Explore Scientific 4.7mm 82° Series Waterproof Eyepiece The Explore Scientific 4.7mm 82° Series Argon-Purged Waterproof Eyepiece is used when very high magnifications are desired. There are conditions that are required to use your telescope at high magnifying power for planetary and double star observations, and for examining the details of many deep sky objects. The 4.7mm will not be used every night, but when those times occur when conditions in the sky are near-perfect, you can get views of planetary detail that you will remember for a lifetime with this eyepiece. Explore Scientific 82° Series 6.7mm Waterproof Eyepiece The 6.7mm 82 degree eyepiece is great for planetary detail, and does not require the perfect seeing conditions needed for higher magnifications. When using this eyepiece with big refractors, it will often be the ultimate eyepiece under normal viewing conditions. Messier 1, the Crab Nebula with a 152mm telescope will astound you. If this eyepiece is used with a 127mm refractor the Dumbbell Nebula will be a perfect fit. With a 80mm telescope, this eyepiece will give you stunningly detailed views at just over 100x magnification, more than enough power to clearly make out the clouds on Jupiter, and will bring the core of Orion’s Nebula clearly into view. Explore Scientific 82° Series 8.8mm Waterproof Eyepiece The 8.8 mm focal length is perfect for observing objects that would benefit from higher magnifications, but that also require a bigger field of view. With bigger refractors (127mm and 152mm) this is an incredible eyepiece to use on Globular Clusters like Messier 13 in Hercules. When using this eyepiece with a 102mm 714 focal length refractor the Eagle Nebula and other similar sized objects will fill your entire view and explode with details. On smaller scopes, like a 80mm 480mm refractor, this eyepiece will delight you with a full view of the Double Cluster in Perseus. Explore Scientific 82° Series 11mm Waterproof Eyepiece The 11mm 82° Series Waterproof Argon-Purged Eyepiece is a popular focal length in the upper-medium power magnification class providing both super-wide apparent field and generous eye relief.
