    In very nice  condition Take a "spacewalk" across the widest, sharpest apparent field... Concept: You may know there's a long history of naming eyepieces after their designers: Kellner, Erfle and Plossl, to name a few. In the late 70's I designed an eyepiece sufficiently radical that I dared attach my name to it. Even today, I must admit a little discomfort when talking about "Nagler" eyepieces. With "Naglers", my aim is to approach the wide angle perspective of naked eye vision, while maintaining the highest degree of sharpness, contrast, and viewing comfort. The goal is to allow the telescope to virtually "disappear," leaving the impact of "spacewalk" viewing. -Al Nagler Available in the following focal lengths: 2.5mm to 31mm Compare a penny to a half dollar to see the relative size between a 50 degree and 82 degree apparent field - almost 3 times the area difference! And while others boast of impressive apparent field sizes, Tele Vue's philosophy of "showing no field unless it's fine" stresses full field image quality as the ingredient for impressive views. Blackened lens edges, anti-reflection threads and rubber eyeguards deliver maximum contrast. Adapter skirts for 2" focusers on larger 1.25" models (12mm Nagler Type 4 and 22mm Panoptic) and rubber grip rings are additional Tele Vue "firsts". Even 2"/1¼" barrel models have an additional feature allowing the 2" extension tube (EBX-2120) to be screwed on, which permits use of 2" filters as well as 1¼". 100% full field visual inspection on our own flat-field test instruments guarantees the performance of every Tele Vue eyepiece...

    In average used condition with nice clean optics, fitted with a nice Crayford focuser so should handle some weight. also supplied with Meade diagonal, finder and matching case Details from the web: The Meade 127mm ED Triplet APO Refractor is tailor-made for fast wide field astrophotography.   Manufactured with the finest Japanese FCD1 ED (Extremely Low Dispersion) glass. This glass is created to achieve a very small change in refractive index with different wavelengths of light.   The Meade 127mm ED Triplet APO Refractor offers broadband multicoated lenses ensure maximum light transmission.   True triplet optical design guarantees the textbook color correction you expect from a premium APO.   The Meade 127mm ED Triplet APO Refractoroffers a fully extendable dew/sunshade - an essential accessory built-in to the design for your convenience.   Package includes William Optics 2" diagonal   For crisp wide field observing and imaging, nothing can beat a true triple-element apochromatic refractor (APO). This is especially true in astrophotography, where APOs have produced some of the most beautiful images of the heavens ever taken from earth. But not all APOs are created equal. Today’s market is filled with semi-APOs (with two lenses instead of three) that don’t bring all the colors to focus in the refractor. Thanks to a two-year design process and a triple objective lens made from the highest quality ED (extra-low dispersion) glass, Meade Series 5000 ED APO Triplets are virtually free of chromatic aberration (color fringing). This means they outperform the most expensive semi-APOs at a fraction of the cost. Expert observers will be delighted by the total absence of color fringing and the scope’s textbook-perfect pinpoint star images. Even beginners will notice the breathtaking high contrast and resolution of a Series 5000 APO. One astronomer commented that the Series 5000 APO “kicked butt on my semi-APO that cost twice as much.” The scope is available as a standalone OTA, or as a package (as shown here) with the new Series 5000 2" enhanced diagonal and an aluminum carrying case. 3-element Apochromatic Refractor design with an Optical Diameter of 102mm. Built-in extendable dewshield and fully multicoated optics. Machined Aluminum Crayford Focuser.

    Size: Small 750mm x 1000mm (HxW) x15Size large 1500x1500mm (HXW) x 10 A brand new cover from AstroJackets combining the best fabric with state of the art manufacturing processes only normally seen in high quality outdoor garments. Most good quality covers are waterproof but they also tend to keep moisture inside the cover which is the one place you don't want it as it can cause corrosion as well as coating damage to mirrors and optics. Being waterproof is great but it only solves part of the problem, it's all well and good if you live in Nevada where an occasional shower or thunderstorm may happen and the rest of the time it's 20 degrees plus and sunny but for those of us not lucky enough to live in an area with the perfect astronomy climate our main problem is combination of high humidity with prolonged periods of rain and dew. Our Tempest series of covers is the answer for the rest of us as it ticks all the boxes that it helps to prevent damage to your delicate equipment. Unobtrusive green fabric so they blend in with your garden or a star party so will less conspicuous to thieves Waterproof Breathable and Anti-static fabric with high chemical and UV resistance Ripstop Fully waterproof taped and bonded seems Rounded rather than square corners so taped seems are uninterrupted preventing water ingress at weaker areas Suitable for extended use of many months (Although we always advise taking the cover off every now and then on sunny days to let it breath naturally and check for critters/crawlies etc) If being used for extended periods we recommend you employ some type of bungee cord arrangement to hold the cover in place in strong winds and gale situations (not supplied) All covers have logo's with no orientation as to up or down, to prevent rebranding by third parties. Cover sizes are nominal and will be slightly smaller when seams are taken into account...

Lower resolutions result in significantly higher frame rates, appropriate for "lucky imaging". VGA (640x480 pixels) offers 113 fps, the maximum rate of 215 fps can be achieved at 320x240 pixels. With its high sensitivity and frame rate, the ASI120MM is very well suitable as autoguider which is connected via a stardard ST guider port.  ..
