Description Ordering Info USA Shipping International Orders Returns Our eBay Store 1. PRODUCT DESCRIPTION Economical 1.25" 45-deg prism diagonal for astronomical telescopes and spotting scopes Produces upright and left-right corrected image for terrestrial viewing and convenient night-time viewing with star maps Hybrid 0.965” - 1.25” configuration allows use of 1.25” eyepieces and accessories in vintage and low-cost telescopes with 0.965” focusers Dual-step aluminum barrel also allows diagonal to fit directly into standard 1.25” focusers Important Note: Please note that the length of the 0.965" nosepiece, as listed below, is 15mm (0.59"). Before purchase, please make sure that the thumbscrew on your telescope is within this distance from the rear end of your focuser drawtube. Otherwise, the thumbscrew will not be able to engage and lock the diagonal. This is a known issue with some vintage telescopes in which the locking thumbscrew on the telescope is recessed by more than 0.6", and this diagonal will not work for you. Disappointed by the lack of quality 0.965" eyepieces for your vintage telescope? Missing a diagonal for that small telescope you picked up in a garage sale? Wish you could use wider angle 1.25" eyepieces with your small spotting scope? Here's the solution you need! Many vintage telescopes sold up to the 1960s, cheap introductory telescopes sold today, and many spotting scopes use a smaller, older, almost obsolete 0.965" diameter format for diagonals and eyepieces. Having a 0.965" barrel severely limits the number of eyepieces and accessories you can buy and use in the after-market. This popular hybrid diagonal from GSO allows 1.25" eyepieces, diagonals, and other accessories to be used in 0.965" focusers, and at once allows hundreds of more common 1.25" format astronomy items to be used with your telescope. GSO's hybrid 0.965"-1.25" 45-degree diagonal features an image erecting Amici glass prism that allows you to look into a telescope at a 45 degree angle. It produces an image that is oriented properly, which means that the image is upright and correct from left to right (i.e., a correct, non-inverted, non-reversed image). This is a great diagonal for daytime terrestrial use with small telescopes or spotting scopes. It can also be used for nighttime astronomy applications, especially when you would like to match the orientation of the star field with "correct" star maps and charts.A unique feature of this hybrid diagonal is the use of a dual step 0.965"/1.25" chrome barrel on the telescope end. While designed primarily for use with 0.965" focusers, the step barrel also allows you to use this diagonal in 1.25" focusers (although your field of view might vignette in some situations if used in this manner). Total length of the nosepiece is 25mm (0.98"); length of 1.25" portion of nosepiece = 10mm (0.39"); length of 0.965" portion of nosepiece = 15mm (0.59"). The prism housing is made of high grade ABS plastic and the end barrels are made from precision machined aluminum. Weight: 2.8oz; 2 end caps included. Made in Taiwan. Please Note: This diagonal can only be used with refractor telescopes and some catadioptric telescopes like Schmidt-Cassegrain, Maksutov-Cassegrain, etc. It not meant for use with Newtonian / Dobsonian reflector telescopes or other variants of Newtonian telescopes. Note: Occasionally, the product you receive might have a slightly different cosmetic appearance or labeling than what is shown. This can often change from batch to batch according to the whims of the manufacturer. However, you will always receive a brand new, original product as described above.

First Class shipments will take 3-5 days to arrive after we ship it. Priority Mail shipments will take 2-3 days. However, these delivery times are NOT guaranteed by the USPS.

You can see the order status or tracking information from your eBay account at any time. Back to Top 4. INTERNATIONAL ORDERING / SHIPPING Shipping Cost: Click on the "Shipping and Payments" tab above and select your country to see your shipping choices and cost. If you need a shipping cost estimate for multiple items, please contact us. Delivery Time: 1) USPS First Class International: Delivery takes about 3-4 weeks after we ship your package. This can frequently take 4-6 weeks or more for several countries (8 weeks for Italy, Argentina, and South Africa; 8-12 weeks for Brazil). THERE IS NO TRACKING FOR FIRST CLASS SHIPMENTS. The information shown in your eBay account is just a customs form number - it is NOT a tracking number as incorrectly indicated by eBay. Once your package ships, we can do nothing but wait until your package arrives. Please do not become impatient and contact us in 2-3 weeks if your package has not arrived. If you don't receive the package in 6 weeks, contact us and we will work with you to resolve the issue. If you don't want to take the risk of this delay, then DO NOT USE First Class mail - use Priority or Express shipping instead. (2) USPS Priority Mail International: Delivery takes 1 - 2 weeks after we ship your package. This can sometimes take 3-4 weeks to several countries. The USPS provides some basic tracking information for Priority shipping. (3) USPS Express Mail International: Delivery usually takes 5-10 business days after we ship your package. You will receive a tracking number with which you can track your shipment from USPS.com. Note: If you use this option, you must send us your phone number when you check-out or else your shipment will be delayed. This is required for international postal forms. Again, these delivery times are NOT guaranteed by the US Postal Service. The most common reason for delays is slow customs inspection and clearance in your country, and can be very long, even for Express mail packages. Upon shipping your order, delivery delays are beyond our control, so do not leave us negative feedback or file a Paypal claim if your package is delayed. Delays are quite common but losses are very rare, so your patience/cooperation will be greatly appreciated. Customs and Duties: You are responsible for any duties and taxes that may be levied in your country. These are not included in the item price or shipping cost. We have no control over these charges and cannot predict what they may be or if they will be levied upon delivery. Customs policies vary widely from country to country (Some countries such as UK are strict about imposing hefty customs duties). It is your responsibility to check with your country's customs office to determine what these additional costs will be prior to bidding or buying. Customs fees are normally charged by the delivery company or your country's postal service, or collected when you pick the item up. These fees are NOT additional shipping charges. Back to Top 5.
